Symptomatic administration, timely medication. First of all, it is necessary to accurately identify the types of pests and diseases, determine the key control targets, and select appropriate pesticide varieties and dosage forms according to the occurrence period and degree of occurrence.

Rational use of drugs. In the case of ensuring the control effect, do not blindly increase the dose, concentration and frequency of application, and excessive application is highly susceptible to phytotoxicity. In the effective concentration range, low-concentration drugs should be used as much as possible for prevention and control. The number of prevention and treatment should be determined according to the residual effect period of the drug and the degree of occurrence of pests and diseases.

Generally, emulsions and wettable powders are mainly sprayed and poured; powders are mainly sprayed; granules are mainly applied by spreading or deep foundation; and liquid absorbing agents are sprayed, sprayed, poured, coated Stems can be.
