Second, when choosing a reasonable dose of pesticide, farmers' friends are used to diluting it with feelings. This is unscientific. If the pesticide is formulated with too much concentration, it will easily cause damage to the crops, produce resistance to pests and diseases, and cause environmental pollution and toxic effects such as human and livestock poisoning. If the preparation is too dilute, it will not achieve the control effect. Therefore, pesticides should be formulated in strict accordance with instructions for the use of pesticides or guidance from agricultural technicians, and the dosage should be properly grasped during the application process. When spraying, it is required to achieve a uniform, thoughtful, and appropriate amount (in order to fully wet the foliage and not lose it). Third, pay attention to cross-use pesticides A pesticide in the same crops on the number of consecutive use of excessive, easy to produce pest resistance or drug resistance, control effect gradually reduced or even invalid. Therefore, care should be taken to use cross-cutting pesticides.
