First, for the object of prevention and treatment, scientifically select the appropriate agent and type.
Second, because the characteristics, habits and hazards of various pests and diseases are different, we need to choose the appropriate practice to apply pesticides according to the sensitive period of the pests, so that the use of less liquid can achieve the desired healing effect.
Third, according to the pesticide network , it should be prevented that a single agent should be used for a long period of time to avoid the resistance of pests and diseases.
Fourth, the concentration of the agent should be accurate when the pesticide is disposed, and at the same time, the agent needs to be uniformly dispersed in the water to be fully dissolved.
Fifth, strive to achieve uniformity when applying the medicine, especially when using the contact agent, the leaf back and the leaf surface should be sprayed into the medicament, so that the liquid directly contacts the insect body, and the application cannot be lost or leaked. The situation of the strain, in order to ensure the quality of the application.
