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 short term, the District People’s Committee will support 100% of the budget for the people. Besides fighting the epidemic, it is also very important to ensure economic and social stability for the people,” Dong said. Mr. Vuong Quoc Tuan, Vice Chairman of Bac Ninh Provincial People’s Committee went to check in Kieu village on May 10. Photo: Bac Ninh People’s Committee. More info with Zing Mr. Nguyen Huy Nga, Head of Agriculture and Rural Development Department of Tien Du district, said that this year’s Winter-Spring rice crop, Kieu villagers planted Thai Xuyen 111 rice variety, which is high quality but capable Insect resistance is not strong. Therefore, if not timely spray treatment, the possibility of crop loss is great. Especially in the current period, rice begins to flower. The type of plane chartered by the Tien Du district government will each take off about 20 liters of medicine that has been prepared in the right dose. The flight process is ensured safely, with the supervision and permission of the competent forces. “We have sent documents to the isolated localities, where needed, the district will support. Up to now, the working group has sprayed nearly 40 hectares of rice,” Mr. Nga said. As of May 10, Tien Du district has 5 cases of Covid-19 in Kieu village (Hien Van commune) and Hoai Thuong village (Lien Bao commune). Through tracing, the whole district has 319 F1 cases and more than 2,000 F2. They were all tested and the initial results were negative Tien Du district has established 11 checkpoints and implemented social distancing according to Directive 16 for Kieu village (Hien Van commune) and Hoai Thuong village, Hoai Trung village (Lien Bao commune). Leaders of the Provincial People’s Committee also regularly check the concentrated isolation area, requesting the quarantined people to strictly follow the 5K message of the Ministry of Health.

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.
