Control method of corn red spider

What is the control method of corn red spider:

The first is the selection of insect-resistant varieties, and the difference in insect resistance between different varieties is very significant. The second is to adopt the strategy of “early eradication of insects, prevention of proliferation in the medium term, and prevention of the later stages” and pay attention to the application of agricultural measures. That is, early manual weeding increased the number of cultivating and timely irrigation at the seedling stage. The third is chemical control. When yellow and white spots appear on the lower part of the cornfield, apply 2% chlorimicarb powder, or use 20% fenpropathrin 3000 times solution, or 2.5% cyhalothrin 3000 times solution, or 1.8% avermectin 2500 times spray. In addition, it can also spray 15% of Lingling EC 2000-3000 times, 25% of acetylene 1500 times, 30% of chlorimazine 2000 times, and 36% of locust EC 1000-1500 times. One, alternate use can effectively control red spider.
