Grasshoppers are intermittent outbreaks, migratory and omnivorous pests. Local practical easy-to-operate solutions: 1. Cultivated and weed-killed eggs. For non-eating crops such as grass crops and potatoes, weeds were cleared of field weeds before spawning. For grazing and foraging crops such as hemp, beans, sunflower, etc., in the spawning period combined with cultivating and weeding eggs, the removed weeds are taken out of the field or concentrated. Attention should be paid to the removal of weeds such as Polygonaceae and Polygonaceae, and at the same time, we must pay attention to the removal of weeds at the Tanabe mantle and clipped land to prevent larvae from moving into farmland. In field where larvae have hatched, it is necessary to fight drugs before weeding so as to prevent the larvae from being transferred to crops. 2. Chemical control technology. Before the 3rd instar larvae (about 10 days after the initial stage of egg growth), matrine and beta-cypermethrin were sprayed for control. In severely affected areas, drug isolation and emergency prevention and control were used to centralize annihilation, timely treatment of larval unevenly distributed plots, and attention was paid to the prevention and control of larvae in the fields of Tanabe, Tajikistan and Abandoned Land.
