Fighting gnats on cabbage
Description of the pest
These pests can be easily recognized by their appearance. The small size of the midges allows them to jump well. The dark color makes them stand out on the green leaves and head of the cabbage. In the warm season, they are especially active.
The real treat for cruciferous flea beetles is the young cabbage leaves. The injured vegetable is covered with many small holes. Subsequently, the plant slows down growth, begins to dry out and dies.
A large number of cabbage midges can destroy the entire crop in a couple of days. Fleas hibernate under a layer of fallen leaves and on the upper balls of the soil. If the affected leaves are not destroyed during harvest, they will spoil the sprouts again in the spring.
