Control methods of vegetable aphids
Agricultural control: clean the garden field in time, remove weeds near the vegetable field, and leave no plant remains of the stubble crops, so as to prevent the parasitism of aphids. Chemical control: to kill aphids and control virus diseases, the aphids should be completely eliminated at the initial stage of the occurrence of aphids, and the aphids should be eliminated before they migrate and spread the virus. The mixture of 3000 times of imidacloprid wettable powder and 3000 times of 48% Lesben EC can be used for spray elimination.
The fastest way to treat vegetable aphids:
1. Protect natural enemies: there are many natural enemies of aphids, such as ladybugs, aphid-eating flies, parasitic wasps, aphid-eating gall mosquitoes, crab spiders, lacewings and entomopathogenic fungi. These natural enemies have a strong inhibitory effect on aphids. Therefore, broad-spectrum pesticides can be applied as little as possible, at the same time, the application of pesticides during the peak period of natural enemy activity can be avoided, and aphids can be artificially reared and released under certain conditions.
2. Artificial control: brush white at the base of vegetables in autumn and winter to prevent aphids from laying eggs. Cut off the injured leaves and residual flowers and burn them centrally to reduce the overwintering insect population. Scrape or brush off the dense overwintering eggs on the leaves in winter, clean up the residual leaves and fallen leaves in time, and reduce the overwintering eggs. When blooming in spring, if you find a small amount of aphids on the flowers, you can use a brush dipped in water.
The above is the relevant introduction of vegetable aphid control methods, I hope it will be helpful to everyone.
