1, scientific management of cotton fields. Do a good job of pruning and chemical control to avoid the shading of fields caused by excessive growth of cotton and the lack of timely control, so as to provide a suitable living environment for the occurrence of blind plagues. For "long cotton", weak branches should be left strong, leaving 1-2 fruit branches to promote their growth.

2, chemical control. As the blind miracidians like to fly, the spawning period is long and the generations overlap. Early prevention and treatment should be carried out. When cotton reaches the bud stage, 100 plants will be successful. When 3-5 nymphs are used, they should be treated with dimethoate to smear the stems or the hearts of the birds immediately. It can be used to prevent and control the locusts at the same time and it will not harm the natural enemies. Adult stage spraying can be controlled with 3% imidacloprid or 10% imidacloprid. Control time should be selected in the morning or evening, spraying once every 5-7 days. Adjacent to the cotton field as far as possible to achieve a unified time control, can improve the control effect.
