Leek late-eye mushroom mosquitoes should be skillfully prevented

The chickoptera is predominantly a larval pest. The larvae are harmful to the young stems of leeks, causing decay, causing the leaves of leeks to wither and die, or the larvae can gather in the underground bulbs and young stems of leeks, causing leeks to be bitten off and missing seedlings.

At present, when a large number of larvae hatch into the peak of pests, it is recommended to take an emergency drug to irrigate the roots. You can choose to use root application with insecticides for root irrigation, which can promote the active ingredients of pesticides to kill leek root insect pests.

In the peak period of adult insect occurrence in April and May, the following agents can be sprayed at 9-11 a.m.: 500 times liquid of the new high-fat film + targeted insecticide spray, which can shield the sense of smell of pests, inhibit the replication of germs, reduce their resistance and dosage, and improve the effect of pesticides.
