With the improvement of people's quality of life, people pay more and more attention to the quality of vegetables. Non-polluted vegetables are also more and more popular. People's pollution-free vegetables have higher requirements for pesticide residues, so it is necessary to master the correct methods of pesticide use. Minimize phytotoxicity issues.
The bait traps and kills the plots that are mainly based on cockroaches. Specific method: fry the peanut cake or wheat bran, add 100% crystal trichlorfon WP or 1 kg of 50% phoxim emulsifiable concentrate per 100 kg of peanut cake or wheat bran, add 10 kg of water and mix well. The poison bait, in the vegetable seedling stage, is sprinkled on the ground in the evening, with 15~25 kg per acre. It not only has good effect on trapping and killing, but also has good trapping effect on larvae and larvae.
In the heavier plots of the ground tigers, 10 times of the above-mentioned pesticides can be sprayed with the fresh grass or fresh leaves of the pests. Made of poisonous grass or poisonous leaves, in the evening (to prevent fresh grass or fresh leaves quickly dry) into small piles in the field, 15 to 20 kg per acre, the next morning pick up dead insects.
Soil treatment Before planting vegetables, 100~200 grams of 50% phoxim emulsifiable concentrate per acre, or 100g of 80% dichlorvos emulsifiable concentrate, 15~20 kilograms of mixed slag, sprinkle on the surface, and immediately plow the ground.
The pesticides can be seeded in the plots where the breeding flies are more serious, and 40% diazinon emulsifiable concentrate (0.4%~0.5% of the seed amount) can be used for seed dressing, and the control effect is better.
Spraying and spraying powdered flies can spray 80% dichlorvos 800~1000 times liquid or 2.5% deltamethrin EC 3000 times on the onion, garlic vegetables and field manure piles to kill in the adult emergence period. Adults reduce the number of eggs and larvae.
Watering garlic and leeks that are heavier in the fly, should be applied during the larval attack. It can be watered with 90% crystal trichlorfon 300~500 times liquid or 50% dimethoate 1000 times liquid. When the amaranth is transplanted, the root can be immersed in a 1000% solution of 50% phoxim emulsifiable concentrate.
