The habits are different. Therefore, the selection of pesticides must fully consider the control objects, crop types and their growth period. Do the right medicine. If the pesticide is misused or misused, it will not be effective.

Master the application period and apply the medicine at the right time. Each disease, insect and grass damage has its best control period. Therefore, the time of application should consider the development period of disease, insect and grass damage, crop growth progress and pesticide quality, so as to timely use the medicine and improve the control effect.
