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).

The orchid varieties, no matter how unique they are, cannot be confirmed that they are “mutant orchids”. Photo: internet. Orchids, the reason for having an amazing variety of designs, colors, and fragrances today is because it is the product of genetic mutations that have been around for thousands of years. Genetic mutations include mutation mutations and recombinant mutations. Mutant mutations can be genetic mutations (loss, addition, replacement of nucleotides pair) or chromosomal mutation (fragment, repetition, inversion, transition, polyploid). The cause of mutation is natural agents such as radiation, ultraviolet rays, heat shock, herbicides … Recombinant mutations are new combinations of genes that have been rearranged in the offspring to create New and different style compared to parents, grandparents, old grandparents. This is due to the independent dissociation, the cross-exchange of the chromosomes. For orchids and other pollen plants, insects (bees, butterflies) also contribute to diversity when pollinating from one plant to another, from one variety to another. Thanks to the genetic variation that they Lan Orchidaceae becoming one of the largest family of plants in the world, with about 28,000 natural species and 100,000 hybrid species; The number of species and genera of orchids has continuously increased over time (Vietnamese Wikipedia). According to the book Vietnamese orchids of Tran Hop (1998) our country has about 137-140 genera, including over 800 species of wild orchids. However, it is impossible to confirm that a certain orchid species detected or collected in the forest was created by mutation or recombination. Adding the tail “mutant spread” is arbitrary. Photo: internet. In fact, the majority of orchids in our country are collected from natural forests or imported for farming. In the country, there is no announcement about orchids created by mutation method. Flower Research Center – Fruit and Vegetable Research Institute, the leading flower agency has started to select and create new orchid varieties by crossbreeding and mutating, but the results are also new at the beginning. Therefore, someone lucky to discover a beautiful and rare orchid variety in the forest or accidentally bought a rare orchid branch at the Buoi market – Hanoi for example, they could give it a name, but adding the tail “mutant spread” is arbitrary. The question is why a group of people intentionally added the tail “mutant spread” and massively propagated and promoted, sold millions and billions of money per eye and bud, while still not knowing how beautiful the face of the flower was. have buyers? Because, there are many people who think or try to explain that the new “mutant orchid” is beautiful, strange, unique than an orchid variety due to hybrid “recombination” or “normal orchid” … tendon “mutation” has hit on the psychology of curiosity, lightheadedness, gullibility of ignorant people. In a nutshell, a series of “mutant orchid” varieties are being propagated and widely advertised, with tens and hundreds of billions of deals is unusual, absolutely no scientific and practical basis, only can say this is a bold game “cheats”. The sensational way of calling “mutation” has hit the curious, light-hearted, gullible mentality of ignorant people. Photo: internet. Actually, the law also has provisions to limit this situation. The Law on Crop Production in 2018 requires that new varieties must be disclosed (name, origin, difference …) before being circulated in the market, however this regulation will not take effect until 2022. In addition, the Intellectual Property Law 2009 stipulates to grant protection to owners of new orchid varieties, even if new varieties are searched, discovered in the forest or collected from orchid collections, if proven. The new variety that is truly different from other orchids has been widely known to the market. However, in order for the law to come to life, apart from the State need to pay more attention to the trees that we have long considered as “secondary”, when there is a market, it becomes “main”, the flower producers and traders. True orchids need to gather, expose the tricks of doing business that are dishonest, not transparent, to build a very promising orchid industry in our country.

Usually, children’s eyelashes are about 150 strands. At birth, the baby’s eyelash length is often short and serves to shield the eyes, help prevent dust … Cutting the child’s eyelashes too soon can cause diseases such as keratitis, conjunctivitis. .. So instead of cutting eyelashes, I want you to have long and curvy lashes, add these to your daily menu. Fish Fish is a protein rich food. The structure of the eyelashes and hair both come from protein. Hence, protein supplementation is a good way to nourish eyelashes. Meat also contains protein, but fish is considered a healthier food because it contains omega-3, which improves circulation. Meanwhile, the eyelashes will also receive more nutrients and oxygen. Illustration. Egg Eggs are also a protein-rich food, helping to nourish eyelashes. In addition, eggs are low in fat, but loaded with many important nutrients. These foods will provide minerals that your child needs for healthy development of eyelashes. Walnuts Walnuts are rich in vitamin E and biotin. These are two substances that help protect the body’s cells from damage, helping young eyelashes to develop long and strong. Sweet potato Sweet potatoes contain vitamin A which works to keep baby’s eyelashes longer and healthier. Lentils Lentils contain protein, biotin, iron, and zinc. These substances all work to promote the growth of eyelashes. Citrus fruits, tangerines Fruits such as oranges, tangerines, and grapefruit are rich in vitamin C. This is an important role in helping blood circulate well, supporting small blood vessels, providing oxygen and other nutrients to help develop eyelashes. Lack of vitamin C can cause eyelash loss. Fresh milk Fresh milk contains a lot of protein and vitamins to help stimulate the growth of baby lashes, thicker. However, mothers need to note that only give babies fresh milk when they are 1 year old.

Smart bowl helps users to lose weight. IGGI is made from Stoneware, a clay-based ceramic material that contains a small amount of stone, has a design “hidden calories” to trick the brain, helping to eat less than normal. The curved bottom of the bowl makes it always look full, and actually contains up to 33% less food, no more than 600 calories. And yet, the red heart of the IGGI bowl helps people to have positive feelings, reducing appetite compared to white dishes. In particular, it also helps users to enjoy more beneficial dishes, especially green vegetables. According to Roderic Andrews, combining red with the IGGI application, the two create a more “balanced” eating habit. Each IGGI bowl has 15 recipe cards and 15 habit cards that encourage users to maintain healthy nutritional habits, persevere in the pursuit of a chosen scientific diet, eat less, but still feel full.
