Bio-pesticide wall in flower wall outside incense
Recently, the reporter learned from the statistics department of Wuhan City that the city’s biological pesticides have presented a “flowering wall outside the wall†in recent years. The statistics of the production and sales of the three major production companies show that the sales of biopesticides in this city are less than 1/1 of their total output. 3, which accounts for only 18% of the total local consumption. More than 2/3 of them are sold to coastal provinces such as Guangdong and exported overseas. Biopesticides are made from microorganisms such as bacteria, fungi, and viruses. Their main features are good insecticidal performance, no pollution to the environment, no harm to humans and animals, no harm to natural enemies, and no resistance to drugs. With the growing awareness of environmental protection, highly toxic and highly-reactive chemical pesticides that are seriously polluting the environment are being restricted, and the use of safe and green biological pesticides is increasing. It is predicted that in the next 10 years, China's biological pesticides will replace more than 20% of chemical pesticides. A person in charge of the Wuhan Municipal Bureau of Agriculture said that in recent years, the city has increased the limit on the use of high-toxic high-residue chemical pesticides, and has completely banned the use of highly toxic and high-residue chemical pesticides in the production of vegetables, and has also implemented a series of policies. Support the development of bio-pesticides and vigorously promote bio-pesticides. However, under such circumstances, Wuhan's bio-pesticides still have a "flowering wall outside the wall incense" situation. According to the person in charge of the Wuhan Pesticide Supervision and Administration Station, the main reasons are: First, biopesticides have a slow efficacy, and they are generally effective in 3 days after application. They are not as fast as chemical pesticides, and many local farmers are reluctant to use them. Second, the prices of biological pesticides are more effective than similar ones. Chemical pesticides are 10% to 20% higher. A senior engineer of the Fertilizer and Pesticide Development Center of Hubei Province believes that poor propaganda and standards are also important reasons. At present, farmers generally have low awareness of biological pesticides and their environmental awareness is not strong. Due to the lack of necessary publicity, farmers have not formed a certain concept for new bio-pesticides and it is difficult to popularize them. At the same time, due to the difficulties in the analysis of the results of the application of biological pesticides, the testing has not yet formed a unified method and the quality standards are difficult to control well, resulting in many biological pesticides currently sold on the market are not real biological pesticides, but biological pesticides. Compounds with chemical pesticides. Even true biological pesticides are not stable enough due to the lack of corresponding quality standards. A person in charge of a biological pesticide production company in Wuhan said that the low level of local agricultural development is the main reason for the biological pesticide “wall flower wall exterior incenseâ€. Coastal provinces have a high level of agricultural development, high requirements for environmental protection, and a large demand for safe green agricultural products. Farmers can be assured of the benefits of using biological pesticides, and the amount of applied biological pesticides is relatively large. In Wuhan and other inland cities, the overall level of agricultural development is relatively low, and the production supervision of green agricultural products is not in place. There is a situation where agricultural products using biopesticides and chemical pesticides compete with each other at the same price. The enthusiasm of farmers for applying biopesticides is not protected, and biopesticides are used. The farmers, in turn, applied chemical organisms, resulting in a decrease in the market share of biological pesticides.

Plant protection experts pointed out that Wuhan's bio-pesticides, “flowering walls outside the wallâ€, are not only typical in Hubei, but also typical in the country. The promotion of biological pesticides is a systematic project. It is not a single unit that can do it. It needs a lot of units to work closely together to form an overall force for promotion. One must increase support. The government must vigorously support farmers in the production of green, pollution-free agricultural products, vigorously restrict the use of highly toxic and high-residue chemical pesticides, and protect the enthusiasm of farmers in the application of biological pesticides. Second, we must increase propaganda. Enterprises and all parties in society must assume responsibility for publicizing the promotion of biological pesticides and vigorously create a good atmosphere for the application of biological pesticides. Third, we must reduce production costs. Enterprises should increase scientific and technological innovation, vigorously reduce energy consumption, reduce production costs, and increase the market competitiveness of biological pesticides. Fourth, we must strengthen agrochemical services. The grass-roots plant protection department of agriculture should give full play to its advantages, teach the application of biological pesticides, guide farmers to apply them correctly, and prevent improper use and cause losses.
