How to prevent tomato virus disease in early spring?
The withdrawal time depends on the weather. Normally, when the temperature is lower than 10°C at night, it is not suitable to withdraw the shed. At this time, the amount of ventilation should be increased to prolong the release time. On sunny days, when the temperature of the shed reaches 28°C or so, the wind is released, and in the afternoon, the air outlet is as late as possible. After entering the result period, the night temperature in the shed should be controlled at about 13°C. Under the conditions of high temperature and strong light, the wind should be released around, so that the shed film can only play a role in blocking the glare and avoid burning the plants. If there are conditions, it can be shaded with a shade net from 10 a.m. to 4 p.m. Weeds and other crop residues around the production site must be promptly removed to reduce the source of the disease. To cut off the transmission route of the virus, spray once every 7-10 days once the liquid, Qi Qi Su, Kang Wei Wei, dimethoate, destroy the liquid and other drugs to kill aphids to prevent the spread of the virus. At the beginning of the disease prevention and treatment, the drug is sprayed once with a solution of the diseased disease, virus A, virus quick killing, and antivirus scorpion, and sprayed 2-3 times in total. The spray should spray auxin, potassium dihydrogen phosphate and other solutions to enhance plant disease resistance.
