The best way to control locusts

<

Seedlings of 100 seedlings with 3 leaves and 2500 shoots were used as control indicators. The average number of leaflets in the upper, middle and lower leaves of each leaf was 200 as the control index.

When the locust occurrence reaches the prevention and control index, it is in the spotting stage and should be sprayed locally to avoid large-scale drug use. It can be used as a low-toxicity and high-efficiency insecticide, such as quick-killing, imidacloprid, and cockroach, and it can also be used to prevent and control three generations of cotton bollworms.
