Diseases and pests of onion vegetables
Bulb plants are quite resistant to diseases and pests, however, the strings committed in the cultivation favor their occurrence. Infection by downy mildew can be prevented by frequent spraying with horsetail preparation. The onion cream attacks plants that grow in shaded places and close to the roots of trees, therefore such places in the cultivation of onions should be avoided. Coordinate cultivation with carrots is preferable, as well as dusting plants with rock meal or spraying Pyrethrum”. Similar measures are used against onion violin, which damages onion leaves. Damaged leaves discolor and break easily. The chanterelle larvae can also be destroyed by crushing them, and damaged leaves are best removed, because new ones will grow up quickly.
