Xia Jingyuan introduced that since the implementation of the highly toxic pesticide alternative test demonstration project in 2005, a total of 132 field screening tests and 77 large-scale demonstration tests have been arranged, and 29 pesticide varieties and 43 matching application technologies have been selected as alternatives. Five kinds of highly toxic organophosphorus pesticides such as amine phosphorus and their application technologies. The implementation of alternative projects has not only effectively reduced the occurrence of human and livestock poisoning and environmental damage, but also more importantly promoted the improvement of farmers’ scientific pesticide application levels, played a positive role in preventing and controlling crop pests and diseases, and improved the quality of crops. Guaranteeing the quality and safety of agricultural products provides a good foundation.
Xia Jingyuan also emphasized that since 2005, due to the short implementation time of the project, some basic work has not yet been carried out, and the promotion of more technologies still requires a great deal of effort. In recent years, with the changes in climate, environment, and planting structure, major diseases and insect pests of migratory, epidemic and borers have erupted year after year. In the case of devastating pest emergencies, there is a small number of substitute products for prevention and control needs, insufficient depth and comprehensiveness of application technology and risk assessment studies, and some product application technologies are not mature enough, and alternative technology training and demonstration promotion are not yet widely used. A wide range of applications and many other issues. The existence of the above problems has seriously affected the implementation of the reduction of highly toxic pesticides, and has also seriously threatened China's agricultural production. Therefore, after the implementation of the first phase of the mission in 2007, it is planned to continue the implementation of the high toxicity pesticide alternative test demonstration project from 2008 to 2010.
Xia Jingyuan pointed out that the main tasks of 2008 include six aspects: First, the determination and screening of biological activity for rice (Saponaria japonica, Saponaria japonica, Cnaphalocrocis medinalis, brown planthopper, white-backed planthopper, planthopper Horses), cotton (cotton bollworm, cotton red spider aphid, cotton aphid, cotton blind aphid, cotton aphid), wheat (subterranean pests, aphids, midge), corn (corn aphid), apple (Peach fruit borer, apple astragalus) , cottonseed, two-leafhopper, cockroach moth), citrus (aphids, scale insects, citrus aphids, wood lice), vegetables (Plutella xylostella, Spodoptera exigua, B. tabaci, cockroach, thrips, aphid The activity of target organisms such as tea plants, tea planters, tea planters, tea planters, soybean planters, sugar cane planters, sugarcane plants, sugarcane plants, groundnut pests, and litchi plants. Assays and formulation screens were screened for 8 active agents or 3 to 4 formulations for each target. The second is field experiment and supporting technology research, which mainly includes the above-mentioned indoor screening of varieties for field plot testing and supporting application technology research, screening and recommending 3 to 4 kinds of effective pharmaceutical agents and supporting application technologies for large area demonstration experiments. , and recommend it to farmers. The third is the risk assessment test, focusing on the risk assessment of pharmaceutical applications that have been screened and proved to be effective. Mainly include: risk assessment of resistance, resistance selection of 6 agents for each target, and evaluation of resistance risk; non-target biological impact assessment, completion of 8 natural enemies living environment, each type of survival A risk assessment test was conducted on 6 types of pharmaceuticals in the environment, and risk assessment was conducted on the effects of the pharmaceuticals on natural enemies; The fourth is the demonstration of the combination of pharmaceutical science and application technology, which is mainly used for the application of the recommended varieties, and demonstration of 3 to 5 kinds of optimized pharmaceutical application technologies on each crop. The fifth is a large-scale demonstration experiment, which is mainly used to establish a large-scale demonstration experiment for the control of 40 target organisms such as rice and other 12 crops. It is planned to establish 70 to 80 pilot demonstration areas. Sixth, propaganda and technical training, mainly through propaganda wall charts, preparation of alternative pharmaceutical application technology manuals, on-site observation meetings and technical training courses, etc., to carry out extensive publicity and technical guidance.
High toxicity pesticide alternative test demonstration for another three years
Xia Jingyuan, director of the National Agricultural Technology Extension Service Center, said in an interview with the reporters at the 23rd China Plant Protection Information Exchange & Pesticides Trade Fair held recently that after the implementation of the first phase of the mission in 2007, the center plans to continue in 2008-2010. Implement a highly toxic pesticide alternative test demonstration project.
