1. Protection of natural enemies: Since we know the natural enemies of aphids, we should protect their natural enemies if we want to better control aphids.During the management of crops or plants, broad-spectrum pesticides must be sprayed as little as possible, especially during the peak period of natural enemy activity, and natural enemies of aphids can be artificially raised and released if conditions permit.
2. Artificial control: In autumn and winter, the base of the trunk can be whitened to avoid aphids laying eggs.Also combined with pruning, the residual flowers, the damaged branches were cut off and burned.After defoliation, the residual branches and fallen leaves are cleaned up to reduce the overwintering insect eggs.When a small amount of aphids are found, they are brushed off with a brush dipped in water.
3. Drug control: If a large number of aphids are found, it is still necessary to spray drugs.Drugs such as imidacloprid, marathon emulsion or pirimicarb will do.You can also use your own pepper water, washing powder preparation spraying, the effect is better.Note that when spraying, it is best to add a proper amount of soap water to increase adhesion and improve the effect.
