Due to the recent high temperature and drought, the red spiders in various crops have been seriously affected. According to our recent survey, cotton fields, peanuts, beans, and sweet potato fields are common, with particular attention to interplanting legumes. Cotton spider mites occur more severely, are still in a state of high temperature and drought in the near future, and crop leaf water content is low, which is very favorable to Red spider harm, reproduction, expansion. It is hoped that the majority of farmers will step up their efforts in prevention Red spider is a collective name for leafhoppers. Its common feature is high temperature and drought, concentrated in the spawning on both sides of the leaf veins. The lower the moisture content of the leaves, the more serious the harm, the stronger the reproductive ability, the vast majority of spiders at 28-30 degrees, relative humidity below 50%, breeding generation after 10 days, generally first damage the lower leaves, and then spread upward. The water content of the drought crop leaves is small, the harm appears more severe, the leaves become whiter, the photosynthesis is reduced, the affected crops are difficult to form yield, and even dry and dead. Control methods: should take early, pressure point, control surface; continuous control strategy. Timely removal of pastures and weeds on the ground to reduce the source of insects. Timely drought irrigation, increase the humidity in the field, promote crop growth, can control the growth of earthworms. In the period from the beginning to the beginning of Ruoqiang, the use of acaricides for continuous treatment of 2 to 3 times, control intervals of 5 to 7 days, spraying should be uniform and thoughtful. Pharmacists can use 1.8% avermectin EC 2000 times, 15% ECG, 75% EC, 20% EC 1000 to 1500 times, etc. It should be used alternately.
