The annual chemical control area of ​​crops in China is more than 6 billion mu, and chemical control is still the most effective and economical method. The contribution rate of chemical control is over 90%. Farmers generally lack the diagnostic knowledge of pests and diseases, and there is no perfect social service organization. Therefore, there are several outstanding problems in the use of pesticides . There are improper selection of varieties, and unreasonable drug selection is very common. According to the current situation of pesticide use in China, experts suggest starting from various aspects and speeding up the rational use of pesticides.
First of all, in accordance with the requirements of Document No. 1, vigorously promote the development of various specialized prevention and control organizations, and recommend special funds to support various specialized prevention and treatment organizations.
Second, it is recommended that the state set aside special funds to support the use of pesticides. Strengthen the research on the technical reserve of safe use of pesticides . Research on technical reserves for rice, wheat, fruit trees, and vegetable fields to reduce the amount of drug use technology, develop new technologies, form models, and actively promote. At the same time, we will do a good job in the demonstration and promotion of new environmentally friendly pesticides.
Third, develop labor-saving and high-efficiency pesticide use technology. According to the optimal particle size theory of droplets and the theory of droplet radius, the research and development of the fine mist spray technology system, according to the "fog kill radius" of different types of pesticides, research and develop the reasonable "fog deposition density" "This can significantly increase the rate of hits, and can significantly reduce the amount of application.
Fourth, strengthen research on pest and disease resistance and agricultural pest resistance monitoring and treatment technologies, and provide technical reserves for early monitoring of resistance genes in the field. Establish a batch of drug resistance monitoring points and drug resistance control demonstration areas based on the area where pests and diseases occur, carry out agricultural pest resistance monitoring and risk assessment, and accurately provide the level of pest resistance in the application area through GPS positioning and Internet technology, and propose to restrict the use of drugs. Technical programs such as alternating medications and rotation medications are used to guide the scientific and rational use of pesticides.
Fifth, efforts should be made to establish a socialized service system, implement a qualification certification system for pesticide practitioners, encourage agricultural technicians to set up various forms of social services such as plant hospitals, establish standardized service procedures and charging standards, and diagnose pests and diseases for farmers. Or directly to the field to serve farmers.
Sixth, strengthen the publicity and training of safe drug use, and focus on training the technical backbone of large technology giants, dealers, professional prevention and control team members and horticultural crop standard parks.
