What to Do When Tomatoes Get Fusarium Wilt? A Detailed Guide to Prevention and Control Methods
Fusarium Wilt Prevention and Control Methods for Tomatoes
Answer: Comrade Ye Jiawei:
Hello. Tomato fusarium wilt spreads and proliferates through infected soil and running water. The most suitable temperature for its occurrence is 28°C, and the greater the soil moisture, the more severe the disease. The specific prevention and control measures are as follows:
1. Carry out a 3-to-4-year crop rotation with onion and garlic vegetables;
2. Prevent seedlings from becoming infected, that is, the seedbed for raising seedlings should use new soil or be disinfected;
3. Disinfect the seeds before sowing. You can soak the seeds in a 0.10% copper sulfate solution for 5 minutes, wash them clean, then germinate and sow them;
4. After the disease occurs, promptly pull out the diseased plants and spray fungicide for protection;
5. From the late seedling stage to the early stage of disease onset, apply fungicide as a soil drench around the roots. The fungicides for spraying and root drenching include: 70% thiophanate-methyl wettable powder at 1000 times dilution, 50% carbendazim wettable powder at 600 times dilution, etc. Use 100 milliliters per plant, once every 7 to 10 days, and 3 to 4 consecutive drenches are sufficient.
