Control techniques of Tomato virus Disease

Virus disease is a common disease of tomatoes. There are two reasons why vegetable farmers feel that virus disease is not easy to treat: one is the transmission route, virus disease is transmitted by whitefly, and whitefly is the most difficult pest to treat in this crop; the other is zinc deficiency is the biggest cause of virus disease. So to cure viral diseases, we must first solve these two problems. Comprehensive prevention and treatment methods for viral diseases: 1. Control whitefly: spray thiacloprid 4000 times solution + Saidan 750 times solution on leaves to control whitefly transmission. 2. Inactivating virus and stimulating growth: spraying Ruipei Zinc 3000 times solution + Jin Ge 15000 times solution +30-40 tablets/barrel of water for human virus, spraying once every 4-5 days, spraying continuously 2-3 times according to the disease condition. 3. Stimulate root growth and improve virus resistance: at the root of tomato, sprinkle 200g/mu of excellent boron zinc +300g/mu of loose soil essence +500g/mu of micro-yield-increasing bacteria, then water, improve soil, promote tomato rooting and improve virus resistance. The above is for reference only.
