On May 16, the Ministry of Agriculture issued an emergency notice to strengthen the prevention and control of pests and diseases in wheat earlines, requiring all localities to take prevention and control of panicle stage pests and diseases as an important task in seizing the summer grain harvest, fully implementing the “one spray and three defenses†subsidy policy, and then taking measures. , and then redouble their efforts to resolutely defeat the "insects to seize the grain" tough fight. On the 17th, the person in charge of the China Pesticide Industry Association said in an interview with reporters that domestic pesticide companies had already prepared and that the production of pesticides in the first quarter of this year had grown more than the same period of last year, and they could fully meet the needs of pest control in the ear of wheat. At present, the wheat in Jianghuai, Huanghuai, North China, and Northwest China has gradually entered the stage of heading, flowering, and grain filling, and this is the critical period for grain weighting. According to the recent monitoring of major crop and disease monitoring and reporting networks across the country, pests and diseases at the ear of wheat have entered a peak period in succession, and the prevention and control tasks are heavy. Notification requirements, prevention and control strategy, with wheat aphids, midge, head blight, stripe rust and other "two insects and two diseases" as the main target, taking into account the powdery mildew, wheat spider prevention and control; prevention and control measures, adhere to disease prevention Combine pest control with control of prevention and control of disease, appropriate control, symptomatic remedy, mixed use of drug and fertilizer, and preservation of weight gain; prevention and control methods, continue to insist on unified organization, unified technical solutions, unified pharmaceutical supply, unified application time, unified control The "five unifications" of the action ensure that the overall prevention and guidance, group prevention and group management, and organizational levels are increased. In order to control the diseases and insect pests in this period and increase the yield of high-yield wheat, experts from the China Pesticide Industry Association and local agricultural technology departments provided detailed technical guidance. Experts believe that “one spray and three defenses†is to mix bactericides, insecticides, and plant growth regulators (such as trace fertilizers, drought-resistant agents, etc.), and that one spray can achieve disease prevention, pest control, and lodging (dry heat) "Prevention of premature aging" and "three defenses" effect. It should be noted that the proportion of pesticide compounding and compounding must be strictly followed. "One shot" is different for different pests and diseases. For example, anti-rust disease should strive to achieve "early detection and early prevention and control". The medicinal agent can be sprayed with triadimefon or diniconazole according to the instructions for use of pesticides to spray 30-50 kilograms of whole plants. Spray once every 7 days, spray 2 or 3 times. The period of prevention and control is also critical, and it must be applied when pests and diseases reach the control targets. In addition, in the formulation of medicinal fertilizers, it is necessary to choose a highly efficient, low-toxicity, low-residue medicine and a reasonable mix of fertilizers. It is reported that in order to ensure the implementation of various prevention and control measures, the Ministry of Agriculture has sent four working groups to nine key provinces (cities) such as Hebei, Shandong and Henan to carry out supervision and control supervision, focusing on inspections of local responsibility for prevention and control. System implementation, prevention and control plan formulation and organization launch, pest monitoring and early warning and prevention and control technologies in place, emergency prevention and control of material reserves, implementation of "one spray and three defenses" subsidy policy, and promotion of specialized unified defense measures, etc. The production line will assist local authorities to carry out prevention and control actions.
