Soybean pests have seriously affected the quality and yield of soybeans, and timely pesticide control is necessary. The Chinese Pesticide Network has compiled a related method for the treatment of related pests for your reference:
(1) Soybean leafhoppers begin to control when 1% to 2% of the plants in the field have a leaf-rolling hazard, 1% avermectin EC 1000 times solution, or 5% flubenzuron emulsifiable concentrate 1500～2000 times liquid, 48% chlorpyrifos EC 1000 times solution, 52.25% chlorpyrifos cypermethrin emulsifiable concentrate 1000 times solution, 2.5% deltamethrin emulsifiable concentrate 3000 times solution, 10% cypermethrin emulsifiable concentrate 2000 times solution, 2.5% cyhalothrin emulsifiable concentrate 1000 Spray control such as double liquid, spray once every 7 to 10 days.
(2) When the amount of nephrotoxic moths is large, it can be sprayed and controlled in the larval stage, using 10% acetamiprid emulsifiable concentrate 1500-2000 times solution, or 2.5% beta-cypermethrin EC 2000-3000 times solution, 50% enemy·le mixture 1000 times liquid, 50% phoxim emulsifiable concentrate 1000-1500 times liquid, 2.5% cyhalothrin emulsifiable concentrate 2000-3000 times liquid, 2.5% cyhalothrin emulsion 2000-3000 times liquid, 5.7% cyfluthrin emulsifiable concentrate 1000~ 1500 times solution, 2.5% high-efficiency cyfluthrin EC 2000 times solution, 48% chlorpyrifos EC 1000 times solution and other spray control.
(3) When the soybean hawk moth is heavier, use 48% chlorpyrifos emulsifiable concentrate 1000 times solution, or 1% avermectin emulsifiable concentrate 2000-3000 times solution, 10% acetamiprid emulsifiable concentrate 1500-2000 times solution, 2.5% high efficiency. Cypermethrin EC 2000-3000 times solution, 2.5% cyhalothrin EC 2000-3000 times solution, 2.5% beta-cyhalothrin EC 2000-3000 times solution, 5.7% cyfluthrin EC 1000-1500 times solution, 90% crystal enemy Spray control of 100 times liquid of 100% insects.
(4) The mulberry brown moth sprays the microbial preparation in the Xiehua period, and can use 10 billion spores/gram of the larvae 1000 times solution or the Beauveria bassiana 300 times solution. Adding the neutral detergent powder can improve the control effect. In the peak period of larvae, you can use 50% chlorpyrifos EC 800 times solution, or 2.5% deltamethrin emulsifiable concentrate 3000 times solution, 2.5% beta-cypermethrin EC 2000-3000 times solution, 5.7% cyfluthrin EC 2000~2500 times solution. Wait for spray control.
(5) Bean leaf roller moth can be used in the initial stage of 10% acetamiprid EC 1500 ~ 2000 times solution, or 2.5% beta-cypermethrin EC 2000 ~ 3000 times solution, 2.5% cyhalothrin EC 2000 ~ 3000 times solution, 5.7% fluorine Pesticide spray control of cypermethrin EC 1000-1500 times liquid, 2.5% high-efficiency cyfluthrin EC 2000 times liquid.
(6) Soybean meal, peanut meal and greenhouse can be covered with silver-gray shade net and insect-proof net. The control agent can be sprayed with 70% imidacloprid water dispersing granule 25000～30000 times liquid, or 20% matrine wettable powder 2000 times liquid, 1% avermectin emulsifiable oil 1500～2000 times liquid and the like.
(7) In the nymphal period, you can use 70% imidacloprid water to disperse granules 25000 ~ 30,000 times liquid, or 20% buprofezin emulsifiable oil 1000 times liquid, 50% leaf sputum emulsifiable concentrate 1000 ~ 1500 times liquid 90% crystal trichlorfon 800 ~ 1000 times liquid spray control.
(8) Bean bean turtles are sprayed in the period of adult and nymphs. The pesticide network recommends that you use 2.5% deltamethrin EC 2000 times solution, or 40% chlorpyrifos 1500 times solution, 24% methomyl water. 2000 times solution, 48% chlorpyrifos EC 1000 times solution, 5.7% cyfluthrin EC 1500 ~ 2000 times solution, 52.25% chlorpyrifos · cypermethrin EC 1500 times solution, 2.5% beta-cypermethrin EC 2000-3000 times solution, 10% acetamiprid Spray control of 1500-2000 times liquid of emulsifiable concentrate.
