How to use pesticides is more effective

Only when the pesticide is used reasonably can it be safe, efficient and economical. Otherwise, not only will not achieve the desired results, but it may also have adverse consequences. The following points should be done when using the medicine:

First, the right medicine. All kinds of pesticides have certain prevention and treatment objects. When controlling a certain pest and disease grass, it is necessary to treat the disease, that is, it cannot cure the disease with the medicine for treating insects, nor can it treat the insect with the medicine for treatment. It should be based on the performance characteristics of the medicament and the occurrence law of the control object. Choose safe, effective, and economical medicines, and don't use drugs blindly.

Second, timely medication. Choosing the right period of drug use is very important for the prevention and control of pests and diseases. Only when the control period is determined, can the full effect of pesticides be fully exerted. It must be used before or immediately after the occurrence of pests and diseases. Only by grasping the key opportunities and timely prevention and control can we get good results.
Third, the right amount of medication. Mastering the appropriate dosage is an important part of controlling pests and diseases. Excessive use not only causes waste, but also increases pollution of the environment, and even causes crop damage and human and animal safety. If the dosage is too low, it will affect the control effect and induce the resistance of pests and diseases. In the application, it should be carried out according to the recommended dosage of various pesticides, and can not be arbitrarily increased or decreased.

Fourth, accurate medication. All kinds of pesticides have a certain period of residual effect and expired. The number of prevention and treatment should be determined according to the residual effect period of the drug and the occurrence of pests and diseases, in order to receive good results. Do not spray when there is strong wind, rain, fog, or high temperature at noon. Spraying is selected before 10:00 am and after 4:00 pm. After the spray, it will rain, and it will be sprayed after the rain. Spraying should be uniform, the fog should not be too large, the spray is meticulous and thoughtful, so that the plants and the leaves can be fully applied on both sides, and the spray is not heavy and the quality of the application is guaranteed.

Fifth, the rotation of medication. Long-term continuous use of a single pesticide in a region is prone to drug resistance, especially some pyrethroid insecticides, systemic fungicides, and the continuous use of control effects will be greatly reduced. Rotation of different pesticides using pharmacological mechanisms is an effective way to delay the development of resistance to pests and diseases.

Sixth, mixed medication. Reasonable compounding of pesticides can improve the control effect, expand the control targets, delay the resistance, save labor, save time and effort, and give full play to the role of pesticide preparations. Although the compounding and mixing of pesticides has great advantages, it must not be combined arbitrarily because some pesticides can be mixed and some cannot be mixed. Before use, fully understand the nature of the pesticide and the possibility of mixing between the pesticides. For pesticides that cannot be mixed, use them separately. After each spray, clean the sprayer in time.
