How to prevent Starscream? How to control Starscream

Red spider, commonly known as "red dragonfly", mainly collects eggplant and pepper leaves. Damaged leaves first form small white spots, then fade to yellow-white, and in severe cases become rusty brown, which causes leaves to fall off, fruits to wither and plants to die. If the fruit is damaged, the peel will thicken and form pinhole-like brown spots, which will affect the quality of the fruit.

Red spider overwinters on crops or weeds in various insect states, such as adults, eggs, larvae and nymphs. Generally, there are 65,438+00 ~ 20 generations in a year, and the peak period is from June to August, which is easy to occur in drought and high temperature years. The harm of red spider is different from that of tea yellow mite. Spider generally occurs when the temperature is above 25℃, usually starting from the middle of the plant, and the damaged leaves turn yellow and fall.

Control methods: clear weeds and crop leaves in time, reduce insect sources, and spray pesticides for protection at the early stage of pest occurrence, which can spray 20% good winter 2000 times and 1% pesticide 2000 times, once every 7 ~ 10 days.
