Control methods and technical measures of potato diseases and insect pests

When planting potato anthracnose 1, it is best to use disease-resistant varieties, and treat them with drugs in time after the disease occurs, and cut off the affected parts in time to avoid reinfection. Water them reasonably during normal maintenance, and control them by trapping after the pest occurs, and then spray them with drugs.

Common diseases in potato planting

1, Late Blight: This disease is an important disease in potato production, which is widespread in major planting areas and often leads to yield reduction. It usually occurs on leaves, petioles, stems and tubers, producing a large number of diseased spots, and there will be a circle of white mold on the edge of the diseased spots.

2. Viral diseases: Viral diseases, also known as degenerative diseases, are extremely harmful to potatoes. After the disease, the plants will become short and deformed, and in severe cases, the yield will be reduced, which is extremely unfavorable to the growth and development of plants.

3. Ring rot: Ring rot is a bacterial vascular disease. Potato infection will cause plant wilting, the tubers at the bottom will rot into rings, and in more serious cases, the plants will die.

Main pests of cultivated potato

During the growth of potato, two kinds of pests, Liriomyza sativae and grubs, often occur. These two pests belong to the high incidence period of Liriomyza sativae in March and April, which will lead to a large number of water shortages and accelerate the death of leaves, while grubs may occur in this growth cycle, which is extremely harmful to the root system.
