The high incidence of tomato virus disease has come, so that the treatment is "immediately"!

In recent years, the area of ​​anti-season vegetables has expanded, and with the infection of seeds and climatic conditions, the tomato virus caused by cucumber mosaic virus has increased rapidly and the damage is serious. Therefore, the prevention and treatment of tomato virus disease has become the focus. The following is a detailed introduction to the prevention and treatment of tomato virus disease:

Selection of resistant varieties according to local conditions

Carry out virus-free seed cultivation and soaking seeds with water for 3 to 4 hours before sowing, and then immerse them in 10% trisodium phosphate solution for 40 to 50 minutes. After rinsing, rinse with water and then germination, or use 0.1% high manganese. Potassium acid soak for 30 minutes;

In the planting area, the field that has not been planted with tomato or has not developed tomato virus disease must be deeply cultivated.

Implement rotations to avoid intercropping and continuous cropping

Reduce and avoid the transmission of tomato virus disease soil and residues, and reduce the occurrence of viral diseases;

Nursery fields and planting sheds should thoroughly remove toxic mixed soils and reduce the source of viral diseases;

Promote formula fertilization technology.

Disease prevention measures during cultivation:

First, planting and cultivating strong seedlings in a timely manner, with appropriate seedling age, and requiring flower buds when planting, but not aging;

The second is to plant early in time, promote the early development of strong seedlings, use plastic shed cultivation, avoid the field onset;

The third is cultivating alfalfa, timely soil cultivation, promoting hair roots, late snoring, early harvest.

Do a good job in early prevention of mites, whiteflies and weeds, and eliminate insect-borne transmission of mites, whiteflies, etc., especially in high-temperature and drought years, pay attention to timely spraying and control of mites and whiteflies, which can effectively prevent virus infection. Reduce the risk of tomato virus disease.
