1. Choose high-efficiency, low-toxic, low-residue pesticides .
When a control object has a variety of pesticides to choose from, it should choose the best effect on the control object, low toxicity to humans and animals and the environment, safe for the ecological environment, and the best for crop safety and economic benefits.
2. Master the key period of medication.
The prophylactic and therapeutic agents should be applied at the early stage of the disease, and the pure treatment is also effective when the disease is light. It is best to control the disease in the early stage or early stage of the disease. The pest control should be controlled when the insect body is small. At this time, the larvae are concentrated, small and weak. It should not be effective too early, and it is easy to lead to excessive pesticide residues in the late.
3. Master the appropriate dosage.
First of all, if the amount of pesticide reaches a certain amount and then increase the dosage, it will not significantly improve the control effect, and may also cause phytotoxicity; secondly, a small number of pests will be beneficial to the reproduction of natural enemy populations; again, the vast majority of insecticides against natural enemies of pests It also has a certain lethality. The higher the dosage, the higher the concentration used and the greater the lethality.
4. Adopt appropriate medication methods.
Spraying and dusting methods may be used on the surface of crop tops; soil treatment methods may be used for soil-borne pests and diseases; seedlings may be used to spread pests and diseases through seedlings; In the prevention and control of woody plant diseases and insect pests such as fruit trees, injection or dressing can be used; granules can only be applied by spraying.
5. Master the safety interval.
The safety interval refers to the time from the last use of the pesticide to the harvest. For example, the control of wheat mites uses 50% anti-procarb, and the maximum use is 2 times per season, and the interval is about 15 days.
6. Alternate rotation of medication.
When the pests and diseases occur severely and need to be used multiple times, the rotation of the agents using different mechanisms of action can avoid and delay the generation of resistance, and effectively prevent pesticide residues from exceeding the standard.
7. Adopt scientific cultivation measures.
Such as the selection of pest-resistant varieties, rational rotation, cultivation of strong seedlings, rational close planting, clean pastoral, reasonable irrigation and fertilization, seed sterilization and soil disinfection to kill germs, using light inducement, taste and other physical methods to trap pests. If you want to remove residual pesticides from agricultural products in your life, you can add biodegradable enzymes in clean water, rinse with fruits and vegetables, rinse with water, or use pesticide degrading enzymes to detoxify fruits and vegetables.
