There are many types of symptomatic pesticides , each of which has its own insecticidal characteristics. If the enemy kills pests, the range is wide, but it is not effective against cockroaches; cockroach is only effective against mites; phoxim has long effect on underground pests in soil, suitable for controlling underground pests; Aphids and other sucking pests; dichlorvos and trichlorfon can also control pests on sorghum, but also cause phytotoxicity to sorghum. Therefore, in the prevention and control of pests, it is necessary to select effective and harmless agents according to the type of pests, developmental stage, living habits, and sensitivity of crops to chemicals. This is the key to rational drug use. The application of pesticides at different development stages is not the same. The resistance of the larvae is the same. Generally, the lower larvae have the worst resistance, especially the drilled pests such as the heartworm, corn pupa and other young larvae on the surface of the crop. And the duration of pesticides is limited. Therefore, when controlling pests, it is necessary to select the most effective period of control of pests.
At present, the low-capacity and ultra-low-capacity sprays promoted to control pests on the surface of crops have the advantage of saving labor efficiency compared with conventional sprays; the application of granules or medicaments to control underground pests is more labor-saving, efficient, and less pesticide-free than spraying. Drifting, etc.; using the systemic agent to apply stem or root zone application method to prevent disease , has the advantages of labor saving, medicine saving, and protection of natural enemies. In addition to selecting the appropriate method of application, attention should also be paid to the amount and frequency of pesticides. If the amount of the drug is small, the purpose of prevention and control is not achieved, and the amount of the drug is likely to cause phytotoxicity and waste.
