How to prevent peanut mites?
First, adult control. In order to eliminate adult worms before the oviposition hazard, use the 90% trichlorfon crystal 800 times solution, or 50% sulphur sulphur 800 times solution, or 40% toxic silk 1000 times solution, or 50% malathion EC 800 times liquid spray, spray once every 10~15 days, even spray 3~4 times.
Second, larvae prevention and control. On the basis of adult control, in order to completely eliminate and control cockroaches, the following methods can be used:
(1) Seed treatment. When sowing, 40% of the poisonous silk can be used, and the medicine, water, and seed kernels should be sown at a ratio of 1:20:1000, or 5% of the silk granules can be mixed with 1 kg of fine soil and 30 kg.
(2) Medicinal irrigation. In the larval hatching period (ie, in the middle and late July, the peanut flowering down the needle period), use 400% of the toxic silk emulsifiable concentrate 800 times, or 40% methyl isoflavone emulsifiable concentrate 800 times, remove the sprayer nozzle, sprinkle the rhizosphere around the plant . Water is poured once after sprinkling.
(3) Watering the liquid. Where there are water conservancy conditions, combined with drought-resistant watering, the liquid is injected into the infusion bottle, and the water is placed at the inlet of the water inlet to allow the medicine to overflow with the water, and 1.5 to 2 kilograms per acre is needed.
(4) Spreading poisonous soil. When the peanuts are under the needle, use 250% of the 250% or 250% methyl isoflavone EC 200ml, mix 20~30kg, mix well and sprinkle around the peanut pier.
