Control methods of Tomato Fusarium Wilt

A: comrade Ye Jiawei: Hello, tomato Fusarium wilt is spread through bacteria-carrying soil and running water. The most suitable temperature for it is 28 ℃. The greater the soil moisture, the more serious the disease. The specific prevention and control measures are as follows: first, rotation of onion and garlic vegetables for 3 to 4 years; second, prevention of disease of seedlings, that is, new soil or disinfection of seedbed; third, seed disinfection should be carried out before sowing. Soaking seeds with 0.10% copper sulfate solution for 5 minutes, accelerating sprouting and sowing after washing; fourth, remove the diseased plants in time and spray to protect them. Fifth, after the seedling stage to the early stage of the disease, chemical root irrigation was carried out. The agents for spraying and filling roots are: 1000 times of 70% methyl topiramate wettable powder and 50% carbendazim wettable powder, 100ml per plant, once every 7 to 10 days, and continuous irrigation for 3 to 4 times.
