According to Mr. Hoang Trung, Director of the Plant Protection Department, the use of drones in pesticide spraying has many advantages compared to traditional methods. Currently, many countries such as China, Japan, Korea … have also applied this technology, especially the Food and Agriculture Organization of the United Nations (FAO) is also interested in and testing this technology in some countries. Africa to control the desert locust epidemic. In recent years, the use of flying equipment in pesticide spraying in our country has become more and more popular. However, there are still many issues that need to be studied when using this device. Photo: TL. With the initiative in the past time, businesses have gone through many channels, imported drones with diverse configurations and capacities … showing the ability to apply this new technology solution quite effectively in pest control. on plants. Later, the drone can also be applied to sowing seeds in the Mekong Delta provinces or to apply foliar fertilizers … In addition to the benefits such as user safety, large capacity, time-saving …, this device also has some issues to be clarified. Accordingly, it is necessary to have a scientific basis, to guide effectively and strictly according to the provisions of law. Currently, there are no official results to confirm that using drones in pesticide spraying helps reduce the amount of pesticides. In the FAO guidelines for use, the drone is still just a tool that must use pesticides in accordance with the dosage stated on the label. In addition, there is the current situation, many places have overstated information and advertising that any crop, any form of medicine can use drones. This is information that has absolutely no scientific basis. The Plant Protection Department recognizes the results from the initiative of enterprises and organizations in researching and applying scientific and technological achievements to production. However, to use it effectively, there is a scientific basis and in accordance with the law. Therefore, in the coming time, it is necessary to have more in-depth and comprehensive studies and evaluations on both the efficiency of use as well as the technical and economic efficiency of the drone. In particular, it is necessary to evaluate the safety level of using drones in pesticide spraying for other objects in the area of ​​use such as aquatic products, bees, etc. In addition, it is necessary to delve into techniques and find out the forms drugs, biological effects can be used appropriately and effectively with drones. Secondly, it is necessary to study plant objects suitable for the use of drones in pesticide spraying. For example, in areas where scattered trees and industrial crops are grown, the use of drones can be said to be ineffective, or as objects on the underside of leaves such as mosquito bugs, anthracnose, etc. Therefore, harmful organisms also need to be evaluated and classified to apply drones appropriately in spraying pesticides. For example, objects lying in the trunk, on the ground, weeds clinging to the base have almost no effect when using a drone. The Department of Plant Protection will also study to provide guidance on the form of drugs to be used with drones. From the perspective of a state management agency, the Department is responsible for clarifying this issue. The use of drones in the past time has been effective and has many advantages on rice, but there have been no scientific studies on other crops. Illustrative photos. Hoang Trung also said that the mechanism of action of the drugs also needs to be evaluated before being used with drones. In addition, it is necessary to evaluate the plant objects and harmful objects that can use drones in spraying effectively. On the other hand, it will be necessary to evaluate and classify according to the capacity and specifications of the drone corresponding to the appropriate crop objects. For example, a large-capacity drone can be suitable for spraying pesticides for rice or some crops, but cannot be used for vegetables because it will destroy the plants… From the above assessments, the goal of the Plant Protection Department is to work with businesses to come up with procedures and documentation for using drones across the country. In addition, the Department will also develop standards for testing pesticides used by drones. Many concerns about the limitations of drones At the meeting, some opinions suggested that there should be more specific and scientific studies in the application of drones in pesticide spraying. According to a representative of the Southern Pesticide Testing Center (Pesticide Department), in order to spray effectively, pesticides must be able to contact the objects that need to be protected or destroyed. However, the use of drones may have many limitations in pesticide spraying such as difficulty in contact with pests and diseases such as brown planthoppers, dry streaks below for rice or thick canopy trees… In addition, the use of drones will use less water than traditional also reduces the effectiveness of the drug. Another problem is that using a drone causes the particles to fall freely but slowly, so it is possible that some of the medicine will evaporate before reaching the leaves. Using a drone with a more concentrated drug concentration than traditional spraying can also cause acute poisoning of plants. In addition, the use of drones will cause waste of pesticides, affecting the ecological environment if used for scattered crops. The Center for Plant Protection in the South (Department of Plant Protection) said that the application of drones in the Mekong Delta is increasingly popular on rice and some fruit trees. Many farmers rate drones as highly effective against pests located at the top of the foliage. The use of drones in pesticide spraying still has many limitations that need to be studied. Photo: TL. However, with trees with uneven heights in the same area such as coconuts, the ability to contact leaves is not optimal because the drone can only fly at a certain stable height that cannot be continuously changed. The height is suitable for each height of the crop, leading to the not equally optimal distance of pesticides to the top of the tree. The Northern Center for Plant Protection also said that it is necessary to study and evaluate the effectiveness of drones and devise ways to use each drug. In addition, there is a need to have scientific assessments of the effects on the environment and plants when using drones to spray pesticides with high concentrations (due to less water). Because normally, the amount of water when spraying pesticides is 400-500 l/ha, while using a drone it is only about 15 l/ha. Mr. Nguyen Quy Duong, Deputy Director of the Plant Protection Department suggested that in the coming time, there should be more assessments on the process and effectiveness of using drones for intercropping areas. According to Mr. Duong, in the Mekong Delta, people now use pre-germination herbicides and except yellow apple snails at the same time, so there is a need for studies on the possibility of using mixed drugs when spraying with drones. In addition, it is necessary to have a baseline standard for testing devices and forms of medicine to come here, it is necessary to clearly state on the drug label the dose used (amount of water) when used with a drone. The Plant Protection Department said that based on the results of businesses and units that have applied drones over the past time, as well as international experience, the Plant Protection Department will develop a master plan to continue researching. Research and perfect both equipment and processes to use in a scientific, safe and most effective way for the application of drones in plant protection. In the immediate future, the Department of Plant Protection suggests that it is necessary to focus on researching and perfecting the drone application process for 5 groups of liquid drugs including EC, SC, SE, SL, ME; 4 groups of solid drugs including WP, SP, WG, GR. Regarding plants, focus on researching and perfecting the process of applying drones to rice (focusing on leaf rollers, brown planthoppers, rice blasts, powdery mildew, herbicides); fall and powdery mildew on corn; aphids, downy mildew on fruit trees (especially citrus, mango, litchi; industrial plants such as coffee, tea, and cashew; caterpillars on pine trees and silkworms on cruciferous vegetables).

In the winter-spring crop 2020-2021, Quang Tri Agricultural Extension Center has implemented an organic rice production model using Guilin organic fertilizer at An Long Cooperative, Trieu Hoa commune, Trieu Phong district to change awareness and transfer of technical processes and organic farming methods to people. From being dependent on chemical fertilizers, people have realized great benefits from applying organic fertilizers. Photo: PVT. The model is implemented on a scale of 10 hectares, 50 participating households. After selecting the demonstration site, the Quang Tri Agricultural Extension Center organized a training session to guide the process of organic rice intensification, especially organic composting. The implementation of organic composting was carried out early (since November 2020). At the same time, the technical staff has coordinated with the Commune People’s Committee and the Management Board of the cooperative to closely manage and supervise the implementation of the model as required by the program. Rice production process using sowing tools, HC95 rice variety has high quality, high yield and good quality. Master Tran Thi Thuy, the technical officer directing the model, said that in the process of planting, households have been instructed to carefully prepare the soil, create a flat surface, and drain water before sowing. Make sure to soak the seeds in the correct technique, regularly check the sprouts, when the sprout is 1/3 of a rice grain (cracked pineapple spikes), the roots are ½ of a rice grain, sow. Healthy, disease-free, productive, high-quality rice fields thanks to organic production. Photo: PVT. Rice is sown by row sowing tool, the amount of seed sown for 1 sao (500 m2) is 3.5 kg. Use composted organic fertilizer for lining and Guilin organic fertilizer during the growth and development of rice plants. Rice does not use chemical fertilizers, chemical pesticides, only biological pesticides are used when pests and diseases occur. Scientific irrigation water regime, suitable for the growing needs of rice plants. Fertilizers are applied in 4 main growth and development periods of rice… Calculating for 1 hectare, the amount of fertilizer for each application is as follows: Apply the last fertilizer before harrowing with 6-7 tons of broken organic fertilizer, 500 kg Guilin microbial organic fertilizer, 300 kg Guilin mineral fertilizer ; first application at rice 20 days after sowing with the amount of Guilin mineral fertilizer: 500 kg; second fertilizer at rice 32-35 days after sowing with 400 kg Guilin mineral fertilizer; 3rd application at rice 62 days after sowing, combined with spraying foliar fertilizer with 300 kg of Guilin mineral fertilizer, 40 packs of Guilin foliar fertilizer. Mr. Doan Tho Hoa, An Long village (Trieu Hoa commune, Trieu Phong commune) participates in the model of organic rice production with an area of ​​4 sao. Meeting with us, Mr. Hoa could not hide his joy and said: The difference of the organic rice production model is the use of Guilin organic fertilizer and the use of manure composted with Trichoderma products. The environment in the fields of Trieu Hoa commune (Trieu Phong, Quang Tri) is greener, cleaner and more beautiful thanks to organic rice farming. Photo: PVT. Compared to HC95 rice, which farmers cultivate in the usual way, the model rice plants are organically healthy, have durable green leaves, moderate green color from the beginning to the end of the crop, and the rice plants are free from pests and diseases from the root At the top, the color of the yellow rice grain is brighter. “During the last storm of the season with strong gusts of wind, conventional farming fields all fell, especially the model fields have strong roots, so they do not fall, which is very convenient for farming. harvest”, Mr. Hoa assessed. Mr. Doan Duc Tam, another household participating in the model, said that when cultivating rice in the organic direction, it will greatly limit the situation where pesticide bottles are thrown away in the field, but instead, the awareness The people’s compliance with the process of caring for rice with organic fertilizers has been increased. “During the implementation of the model, from planting, tending to harvesting, my relatives and I always feel secure, without fear of toxicity when taking care of rice,” said Mr. Tam. Multi-faceted benefits In the process of rice production, if using inorganic fertilizers for many years, without adding organic fertilizers as well as overusing inorganic fertilizers, it will cause harm such as increasing the susceptibility of plants to diseases. , kill beneficial microorganisms, make many arable land areas lose fertility, imbalance of nutrients in the soil, hard soil, decrease crop yield and increase production costs. impact on the environment and human health… Not using chemical pesticides, focusing on integrated pest management in the field has shown farmers countless benefits. Photo: PVT. The application of organic production processes increases the fertility of the soil, increases the minerals and effective microorganisms for the soil, has a very good effect on soil improvement, especially for the soils that have been and are being developed. degraded. In the long run, it will help the rice plant’s better resistance to pests and diseases. During the flowering period, the field will be less infected with planthoppers, dry, give long cotton, rice is free of pests, rice is clear, rice is soft and has a characteristic aroma. Economically, the yield is estimated at 57 quintals/ha for the HC95 variety, with the selling price of 9,000 VND/kg, giving a profit of 25 – 27 million VND/ha, 10-15% higher than the mass market. In addition, reducing the amount of sowing seeds by using a sowing tool, making rice plants grow healthy and balanced, this is an important factor contributing to improving productivity and economic efficiency. In terms of environment, ecology, using Guilin microbial and mineral organic fertilizers, combined with manure, stubble decomposition products, creating a favorable environment for beneficial microorganisms, improved soil. Better yet, the rice plants grow in balance, the environment is safe, the field ecosystem is secure, there are fish, snails, and crabs… living in the rice fields. Organically produced rice not only ensures quality and productivity, but also significantly reduces production costs. Photo: PVT. Developing agriculture according to organic farming methods not only contributes to the creation of organic products that are beneficial to human health, but also raises awareness and changes farming methods in rice production towards organic sustainable, ensuring safe products, the country’s environment is not polluted, contributing to the protection of the environment and field ecosystems. According to Mr. Phan Ba ​​Dinh, Chairman of the People’s Committee of Trieu Hoa Commune, Trieu Phong District: Local households have also felt the risk of abusing inorganic fertilizers, abusing chemical pesticides, affecting quality. agricultural products, environment and public health, so the model implementation is highly accepted by households. Mr. Dinh has learned from experience: If the technical process in the model is followed, such as using microbial organic fertilizers and Guilin mineral fertilizers, combined with manure, Trichoderma; If the amount of water is guaranteed, the weather is favorable, it is necessary to go through many production crops, the fields are improved, the fertility of the soil is improved… “From the initial support of the Provincial Agricultural Extension Center, it has helped households to firmly grasp and understand the technical stages of organic production that are different from mass production. In the next seasons, we will direct, and have supportive policies, and at the same time continue to propagate and replicate the model, encouraging farmers to implement this superior farming model,” Dinh said. know.

Black-headed caterpillars cause 70-80% damage in the coconut orchard they appear. According to the Department of Agriculture and Rural Development (Agriculture and Rural Development) of Ben Tre province, since the discovery of the black-headed pest in July 2020 to the beginning of April 2021, the whole province of Ben Tre has more than 160 hectares of coconut orchards. black attack, in which the area heavily infected with burnt leaves was 51ha. This is the area where more than 40% of the leaf boats are damaged out of the total number of leaf boats surveyed based on the guidance of the Southern Plant Protection Center (Plant Protection Department). Currently, the blackhead worm continues to cause harm in districts of Binh Dai, Chau Thanh, Mo Cay Nam, Mo Cay Bac, Ben Tre City and Cho Lach. The largest outbreak was in Huu Dinh commune of Chau Thanh district with over 66ha of infected coconut orchards. Mr. Dang Thanh Hai, in Huu Nhon hamlet, Huu Dinh commune, has 2,000 square meters of coconut over 40 years old that are being attacked by blackhead worms, causing heavy damage. Mr. Hai said that because the coconut tree is 30-40m high, it is impossible to spray this insecticide, so he had to destroy it. “Coconuts grown for a long time, used to suffer many diseases but did not die, now the black-headed worm eats them, causing mass death of coconuts, irreversible. Blackhead worm is very dangerous because it eats coconuts very quickly, within 2 months it has spread, cannot be cured “- Mr. Hai said. Up to now, the areas of coconuts heavily damaged by blackhead worms in Phu Long and Dinh Trung communes, Binh Dai district, are basically controlled by functional agencies. However, the application of mini aircraft to control the epidemic is ineffective. In other harmful blackhead worm detection locations, the Department of Agriculture and Rural Development has coordinated with local authorities to organize workshops and trainings to guide farmers in implementing control measures. Up to now, farmers are basically aware of the harm level as well as basic control measures, self-treatment and spraying. Mr. Phan Tan Loc, Head of Agriculture and Rural Development Division of Chau Thanh district, said: “The black-headed worm attacked about 80 hectares of the district’s coconut garden. The locality has organized the spraying of drugs according to the instructions of the authorities, but it is not effective. Therefore, the district proposes the Provincial People’s Committee to extract funding for researching special treatment drugs, soon going to the army to spray simultaneously to stamp out the epidemic, to avoid widespread spread; deploying extensive propaganda to people about temporary management measures for people to know and implement ”. Implement temporary management measures The black-headed worm attacked the coconut garden in Ben Tre. After the outbreak of black-headed worm, Ben Tre Plantation and Plant Protection Department coordinated with Southern Plant Protection Center to take samples of harmful pests and send identification samples. Center for Plant Inspection and Inspection, the Plant Protection Department has identified this pest with the scientific name Opisina arenosella Walker – a serious pest originating from southern India and Sri Lanka. In Vietnam, the blackhead worm that harms coconuts is a new pest that has not been researched and has a registered pesticide for control. Therefore, the Plantation and Plant Protection Department of Ben Tre province has issued a temporary control measure based on the reference information of the Southern Center for Plant Protection and some actual records of the unit. At the same time, to carry out propaganda and training on knowledge of blackhead pest prevention for farmers in Ben Tre. In addition, the District Plantation and Plant Protection Station also actively coordinates with relevant sectors to actively propagate, organize training courses, guide coconut farmers to recognize and manage blackhead worm. . Regarding the temporary management measures, the Department recommends that farmers regularly visit the garden to timely detect and implement preventive measures. In case of detecting a black-headed worm, people quickly prune, destroy leaves and leaves that are damaged by worms, burn or bury them in water to reduce the pest population effectively and safely for people and the environment. . This is an important and necessary measure to take immediately after a pest is detected. People should also balance fertilizer, divided into many fertilization times a year. Mr. Huynh Quang Duc, Deputy Director of the Department of Agriculture and Rural Development of Ben Tre province, said: The view of the Ben Tre Agriculture sector is to coordinate with companies and businesses inside and outside the province to immediately apply quarantine measures to reduce honey. number of worms, limit the spread while waiting for research results to have a complete process. Pest control with the motto of environmental protection, organic coconut production has been successfully built by businesses and farmers. To stamp out epidemic diseases, but ensure a stable production environment and especially protect people and animals living under coconut canopy … In the long term, deep management of blackhead by biological means to ensure the environment, ensure the quality of coconut products with the quality of food safety accepted by the domestic and foreign markets. According to Mr. Duc, Ho Chi Minh City University of Agriculture and Forestry is speeding up the implementation of the project “Research and assessment to determine the harmfulness of coconut leaf-eating worms and build models and propose solutions. biosafety management and prevention in the province of Ben Tre ”to apply results in production. The school has set up a room for propagating parasitic bees at the Department of Planting and Plant Protection, expanding one room at the Center of High-tech Agriculture to both research and release quickly parasitic bees. Good on black-headed worm pupae and larvae. Mr. Vo Van Nam, Head of Plantation and Plant Protection Department of Ben Tre province, said: The Department has recorded many natural enemies of the black-headed worm that harms coconut in gardens in Binh Dai district. Typically, parasitic bees, stink bugs catching prey, weaver ants, pincer beetles … Therefore, the Ben Tre Department of Cultivation and Plant Protection recommends that people choose pesticides that are less toxic, less harmful to the kind of natural enemy. In the coming time, will aim to control blackhead worm with biological measures because Thailand has successfully applied this measure with parasitic bees. In addition, the Department is also cooperating with the Ho Chi Minh City University of Agriculture and Forestry to conduct research as well as to breed this natural enemy. “Can Tho University has also studied and tested a probiotic to prevent blackhead worms with plant extracts. Initial testing on some infected areas has been effective, farmers are very excited. Ben Tre is building organic coconut gardens, so the protection of these coconut areas with bio-products is extremely necessary. Next time, this unit will continue to test to complete the process and products. If the product continues to achieve high efficiency, we will put into the process to recommend farmers to use “- Mr. Nam said.

Preliminary processing of lychee for export at Ameii Joint Stock Company. On May 9, the Plant Protection Department (Plant Protection), the Ministry of Agriculture and Rural Development returned to the Red Dragon Production and Trade Company in Thanh Ha district (Hai Duong) to operate and take over the system. fumigation steam for litchi fruit export to Japan and other “fastidious” markets. To meet the demand of exporting fresh litchi fruit to “fastidious” markets, Hai Duong province has been approved by the Department of Plant Protection, Ministry of Agriculture and Rural Development for the installation of four fumigation systems. In which, Red Dragon Production and Trading Company installed two systems, Ameii Vietnam JSC installed one system and Hung Viet Agricultural Exporting Company installed one system. The installation of the fumigation system is undertaken by the Institute of Agricultural Electrical Engineering and Post Harvest Technology. The systems of fumigation and disinfection treat litchi fruit with Methyl Bromide have capacity of 15-16 tons of fruit / day. The fumigation system to treat litchi fruit with Methyl Bromide has the ability to clean 100% of diseases on litchi fruits. A fumigation system has a complete installation cost of more than 420 million VND. After checking the installation and testing process, the Plant Protection Department evaluated the sterilization systems of Hai Duong to ensure the operational standards and quality of sterilization, qualified for operation. According to the Department of Plant Protection, Hai Duong province is currently the unit with 4/5 fumigation systems nationwide. Expected litchi crop, Hai Duong province will export about 1,000 tons of fresh lychee fruit to Japan.

The application of scientific advances in agricultural production is an inevitable trend to reduce labor force and increase crop productivity in order to bring about high economic efficiency. In particular, the use of drones (drones) to spray plant protection drugs (BVTV) in Long Dien district initially showed effectiveness not only in production, but also contributing to protecting the health of farmers. . Farmers watched the demonstration of flying equipment spraying pesticides by the District Farmers Association in coordination with SNEWRICE JSC to perform the winter-spring crop 2020-2021 on the fields of An Nhut commune. 30% DISCOUNT OF Pesticides The device for spraying pesticides for plants is unfamiliar to many farmers in the province, but to farmers in Long Dien district, this device is quite familiar. In the Winter-Spring crop of 2020-2021, the District Farmers Association in collaboration with SNEWRICE Joint Stock Company (Ho Chi Minh City) held a demonstration of spraying pesticides by drone on more than 30 hectares of rice in An Nhut commune (the company supports 100 % injection). This form initially shows practical effectiveness and promises to be able to deploy on a large scale in the near future. This is also an activity in the project of implementing high technology application in agricultural cultivation, improving production efficiency for farmers. With drones, the droplets coming out of the nozzle are very small and smooth, helping the farmer reduce the actual amount of water needed while ensuring even surface spread and high efficiency. The spraying of pesticides on rice by drones also increases labor productivity by 15-30 times, shortens the spraying time per unit area; 30% reduction in pesticides compared to conventional spraying. Witnessing the spraying equipment in the field with his own eyes, Mr. Huynh Van Manh (An Lac hamlet, An Nhut commune) said that in the past, he sprayed pesticides with a bottle on his back. Although he is equipped with protective equipment such as raincoats, gloves, and boots, he cannot avoid inhaling the smell of medicine. In this Winter – Spring season, he registered with the Farmers’ Association to spray pesticides with drones on his family’s 4ha of rice. “With the manual spraying method, for each hectare of rice, I have to pay 400 thousand dong to hire labor. In the Winter – Spring crop 2020-2021, I spray with a drone, the cost is lower, only 350 thousand VND / ha, and the amount of medicine is reduced by nearly 30%. So I will use drones to spray drugs in the coming rice crops, ”said Manh. According to Huynh Trung Thanh, Director of An Nhut Agriculture – Service Cooperative, spraying with drones saves water and pesticides while reducing rice yield loss by 150-200 kg / ha compared to conventional spraying. rice is not stepped on like when sprayed with a can. “On the fields of An Nhut cooperative, farmers linked production and cultivated simultaneously on an area of ​​more than 200 hectares, so the use of drones to spray pesticides is very effective,” said Thanh. for more info. Using drones to spray pesticides helps to save production costs, reduce the impact of pesticides on the environment and affect water and soil sources. ESTABLISHMENT OF HIGH-TECH AGRICULTURAL CO-operative Over the past years, farmers in Long Dien district have applied agricultural mechanization and brought higher efficiency in production; Contribute to agricultural restructuring, improve the quality of agricultural products and increase profits. However, the application of flying equipment in spraying, fertilizing … is still limited due to large investment costs. According to Mr. Huynh Van So, Vice Chairman of Farmers Association of Long Dien district, the spraying of pesticides with drones has shown many benefits to the fields in An Nhut commune. Therefore, on April 15, the District Farmers Association cooperated with the TT.Long Dien Farmers’ Association to set up Green Leaf High-tech Agricultural Cooperative. The cooperative has 7 members, specializing in providing services and applying science and technology in agricultural production. “Since the use of drones in agriculture in Long Dien district is relatively new, the District Farmers Union will coordinate with SNEWRICE JSC to disseminate this technique step by step. Step one, the company will make drone spraying service for farmers. Step two, proceed to training and implementation in cooperatives. Then, when the effectiveness has been verified over time, the Farmers’ Union levels will be massively deployed in the fields of An Nhut, An Ngai and Tam Phuoc communes, ”said Mr. So. The adoption of drones for agricultural production is an important transition in accelerating the mechanization of the agricultural sector. This step contributes to promoting competitive advantages, improving the efficiency and quality of agricultural products and increasing farmers’ income.

Proactive technology In Vietnam, since 2018, many localities have demonstrated the use of MBKNL in fertilizing and spraying pesticides for agricultural production. However, the results of using MBKNL in the field lack the stability, the accuracy of the equipment is not as expected, especially in the context that the current pesticides are mainly used for traditional spraying equipment, with the amount of mixed water many times higher … Facing this situation, the Ministry of Agriculture and Rural Development and the Ministry of Defense assigned the National Center for Agricultural Promotion (NNNN) to co-ordinate with the Plant Protection Institute, Hoa Lac High Tech Research and Application Institute and its management unit. The Ministry of Defense carried out the task of “Completing the technical process of using unmanned aircraft (UAV) – HLD18 spraying pesticides on rice plants”. Close-up of the HLD18 drone and the field of Truc Hung commune (Truc Ninh, Nam Dinh) – where the demonstration of aircraft spraying pesticides. Photo: MN Close-up of unmanned HLD18. “If we use the manual method to spray pesticides a day, 3 people can only spray 20 samples. But now with this aircraft, we no longer have the trouble of spraying pesticides, the productivity is significantly increased.” . Farmer Nguyen Van Phong (Truc Hung commune, Truc Ninh district, Nam Dinh) Mr. Le Quoc Thanh – Director of VNA, said that this device is made in Vietnam, so we have complete mastery of technology, software, hardware and warranty, training “pilot” to transfer to units, cooperation groups, agricultural services … Especially HLD18 equipment ensures security and defense as well as the issue of licensing flight zones for equipment. To evaluate the results of the trial using MBKNL HLD18 to spray pesticides on rice plants, VNA recently held a demonstration conference on using MBKNL HLD18 in Truc Ninh district, Nam Dinh province. In the experimental field, the participants and farmers witnessed the “pilots” in the flight control technology demonstration service group HLD18 spraying pesticides with different flight speeds at different formulas. Experimental results show that using HLD18 aircraft helps to reduce 5% of the input pesticide, and 5-10% of water. The use of airplanes helps to control rice diseases effectively by quickly suppressing epidemics and saves time for pest management, and at the same time reduces rice yield loss by 1-2% / ha compared to spraying pine usually because rice is not trampled during the spraying process. The amount of pesticides sprayed by MBKNL on the soil and water at the initial stage of rice plant development has not changed compared with the traditional method. However, to a later period, the amount of pesticides on rice plants is higher due to the decrease of spraying in the environment. The working capacity of an aircraft HLD 18 ranges from 10-20ha / day. Replication At the seminar, Mr. Le Quoc Thanh – Director of NTPPR shared: “From practice, the biggest effect of the model is to isolate farmers from pesticides, thereby helping to protect people’s health and The machine helps to increase working efficiency, not to be afraid of the terrain, save water and drugs, and increase production efficiency “. Farmers and delegates visited the rice growing model using HLD18 drones in Truc Hung commune (Truc Ninh, Nam Dinh) Also at the conference, VNA awarded certificates to 18 trainees trained to control MBKNL HLD18. In addition to the above advantages, through the specialized agency model, the operator is also trained to use MBKNL equipment to serve farmers. The initial achieved results will serve as the basis for Nam Dinh province in particular and the Red River delta provinces to organize the replication, contributing to increase the rate of technology use in the field. As a unit with more than 700ha of area for cultivating hybrid rice varieties, Mr. Lam Van Chieu – Deputy Director of Cuong Tan Co., Ltd. (Truc Ninh, Nam Dinh) said, Cuong Tan is the coordinator of the project NN- 08II. In the process of implementing the project, the company sent staff to participate in the control engineering class MBKNL HLD18. “After more than 10 school days, trainees have been practicing directly on the rice fields of Cuong Tan Co., Ltd. and up to now, it can be said that the basic techniques of controlling MBKNL HLD18 to spray pesticides have been proficient “- Mr. Chieu shared. Also at the conference, TTKNQG handed over to Hai Duong Agricultural Extension Center and Cuong Tan Co., Ltd., each unit 3 MBKNL HLD18 for application of pesticide spraying in rice production. Ms. Pham Thi Dao – Director of Hai Duong Agricultural Extension Center said, Hai Duong currently has about 115,000 hectares of rice cultivation. The average rice yield is 745,000 tons / year. With the handover of HLD18 aircraft by VNA, this will be an incentive for farmers to be able to efficiently produce rice, reduce labor, limit exposure to pesticides while ensuring productivity.

When the movement of young workers to big cities for work takes place quickly, it leaves a “headache” about human resources serving agricultural production. Modern machine tools are considered as the optimal solution to solve the problem of lack of manual labor in the field. To solve the problem of sowing, seeding machines, rice transplanting machines gradually replace. To deal with the harvest, combine harvester is widely used. For post-harvest preservation, large capacity drying systems are utilized, farmers sell fresh rice directly instead of exposing themselves to sun drying as before … Drone demonstration workshop in Vong Dong commune (Thoai Son) However, although machines support many stages, but with rice care tasks, such as weeding, mixing, fertilizing, spraying pesticides … still need a lot of manual labor. “Each rice crop must be sprayed with many drugs, not to mention the pest must increase the number of sprays. My family cultivates 3ha of land, employs 2 people to spray it for more than half a day, and has to supervise to make sure they spray the fields. The rice was being sprayed in the seed, the rice was trampled down, the recovery was slow, and it looked pity. These days, when it is urgent, it is not easy to find someone to spray drugs ”- said farmer Tran Van Minh (Vong The commune, Thoai Son). For the pesticide spray problem, the use of Drones (unmanned aircraft) as a salvage. Farmer Phan Thanh Bac (Vong Dong commune, Thoai Son) said that his family has more than 5 hectares of rice land, each time he hires someone to spray it is very difficult and takes a lot of time, so he has invested more than half a billion dong to buy Drones. both used for home fields and hired by pesticide spraying services. According to Mr. Bac, if the person carrying the sprayer can take 2-3 hours to finish spraying 1ha of land, with Drone, it only takes … 8 minutes. “Since the introduction of the Drone into the field, it helps to reduce a lot of labor, reduce costs but increase rice yield. Less than 1 year, I have been spraying pesticides for more than 3,200 ha of rice farmers in the district. With the cost of spraying 180,000 VND / ha, after deducting all the costs, I have recovered the capital to buy the original Drone ”- Mr. Bac said. As expected, Mr. Bac will invest in buying an additional drone to expand pesticide spraying service. Need to support farmers Ngoc Anh Food Company Limited (Thoai Son) is a distributor, maintenance and training drone for Dai Thanh Joint Stock Company. Director of Ngoc Anh Food Company Limited Cao Van Tan said that over the past 1 year, the company sold 9 P-GLOALCHECK pesticide spraying aircraft to farmers in the province. Because the selling price is still quite high (from 534-609 million VND / machine), it is mainly sold to farmers with a large field area, first serving their home, then spraying pesticides service. Through practical assessment, Drones can reduce the loss of 30% of pesticides in spraying, reduce labor by about 20 times, save 95-97% of water, limit environmental pollution and more importantly, farmers do not continue. Direct contact with pesticides such as spraying should limit health effects. The special feature of the Drone provided by Dai Thanh is a versatile machine that is not fussy about drugs (dissolved powder, water or oil emulsion), applying centrifugal spray technology to bring high accuracy. The particle when coming out of the nozzle is very small and smooth, helping to reduce the actual amount of water needed while ensuring even surface spread. Centrifugal spray technology makes water droplets swirl, making the contact with pests on the underside of the leaves more effective, the ability to concentrate Drone to spray the drug quickly. Drones are also capable of spraying at night, accurately spraying with the control of on-board spray technology, pest diagnosis application to synchronize data with the aircraft to automatically spray into the pest area. Using Drones, it helps to reduce the losses of 150-200 kg rice / ha compared to conventional spraying because the rice is not trampled. Mr. Vo Thanh Manh (Deputy Head of Technical Department, An Giang Agricultural Extension Center) said that An Giang is the province with the second largest rice production area in the Mekong Delta. agricultural concern. Especially, for nearly 2 years now, the technology of unmanned aircraft spraying pesticides on rice and fruit trees has started to develop quite strongly. This is an activity in the project of implementing high technology application in agricultural cultivation, improving production efficiency for farmers in the province. Although the utility of the Drones has been proven, the problem is that the price of Drones is still high, many farmers are difficult to access. To expand the area served by Drone, it is necessary to have policies for farmers to borrow loans to support interest rates or business units to coordinate with banks to support capital for farmers. That is also how to solve the problem of lack of human resources in agriculture today.

The smart rice transplanter that combines the functions of sowing, cultivating rice, fertilizing, and spraying pesticides has been applied at An Nhut Agricultural and Service Cooperative from 2019. LABOR REMUNERATION Over 15 years of growing pepper, Mr. Nguyen Hoang Phuong (Tan Hoa village, Bau Chinh commune, Chau Duc district) said that in the past, from tending to harvesting, he had to do it by hand. To water 2.5 ha of pepper, 2 labor takes 7-8 hours to complete. In 2017, he invested 40 million VND in installing a drip irrigation system. Mr. Phuong commented, compared to the traditional irrigation method, drip irrigation has many outstanding advantages such as: saving water, minimizing water loss, making the soil always fresh and porous; Saving water pump electricity and reducing labor. In addition, this irrigation system can also combine fertilizer, medicine and irrigation water through the drip tips. “From the day of installing the automatic watering system, every time I water the garden, I just turn on the circuit breaker, set the hour and go to other jobs. In addition to reducing labor, the automatic irrigation system also helps to save water. In the past, the average amount of watering was 300m3 / ha / time, since the application of drip irrigation has been reduced to 60m3 / ha ”, Mr. Phuong compared. In the rice fields of farmers in Phuoc Hoi, Lang Dai, Long Tan, Phuoc Long Tho communes (Dat Do district), the system of machines such as tillage and transportation machines, water pumps, combine harvesters, Harvesting in series, rice dryers appeared more and more, gradually replacing the labor force of farmers. Information from the Department of Agriculture of Dat Do district shows that more than 16,000 hectares of cultivated rice by farmers have used almost 100% machinery in the stages of soil preparation and harvesting. Mr. Nguyen Van Tam, an agricultural officer in Phuoc Long Tho commune, said that almost all stages of rice production in the locality have been mechanized. With the implementation of agricultural mechanization, when sowing sowing, there were plows and land-plowing machines, when the harvest time, there was a combine harvester to serve at the place. In addition to bringing about higher economic efficiency, the application of mechanization also solves one of the difficult stages of the agricultural sector today, which is the source of labor when only 1-2 operators and use are possible. work, help farmers reduce labor costs. CONTINUOUS SUPPORTING MACHINERY IN AGRICULTURAL PRODUCTION According to the Department of Agriculture and Rural Development, at present, the province has more than 400 types of machines serving the mechanization of agricultural production, with the number of more than 105 thousand units. In which, machinery is concentrated mainly in stages such as soil preparation, irrigation, spraying of pesticides, transportation and fishing means. The stages of harvesting, preliminarily processing and preserving agricultural products currently only stop at a number of models of applying preliminary processing technology and preserving vegetables and fruits after harvest. The average level of mechanization of the stages in agricultural production such as: land preparation reaches 100%; 80% of care and spraying of plant protection products; the harvest stage reaches 40%; 30% drying stage. The application of agricultural mechanization has contributed to reducing labor, ensuring seasonality, increasing productivity, quality and reducing post-harvest losses. Mr. Vu Ngoc Dang, Deputy Director of the Rural Development Sub-Department (Department of Agriculture and Rural Development), said implementing the policy of developing household economy in agriculture and fisheries (Resolution 05/2018 / NQ-HDND) and policies to support equipment and materials for the development of cooperatives in the agricultural sector in the period of 2019-2020 (Resolution 39/2018 / NQ-HDND), up to now, the Sub-Department has supported more than 300 machines and equipment. serving production with more than 250 households / cooperatives operating in the agricultural sector such as sowing machines, burying fertilizers for An Nhut Agricultural and Service Cooperative; Package irrigation system, tillers, chain saws for Thai Duong Agricultural Cooperative … In the coming time, the Department will coordinate with localities to continue reviewing and making statistics on the number of machines and equipment; from there to build production plans towards focusing on developing plants and animals with strengths, competitiveness and in accordance with the province’s development planning. “For the project of agricultural mechanization and the application of post-harvest technology (under the Scheme on restructuring the agricultural sector of BR-VT province in the direction of increasing added value and sustainable development to 2020, vision to 2030), after being approved by the competent authority, the Sub-Department will coordinate with relevant departments and agencies to organize propaganda and mobilization of post-harvest agricultural mechanization through models, project points, seminars, seminars ”, Mr. Vu Ngoc Dang more information.
