How can I get rid of funguses in the soil?
Q. I have 2 tomato plants from last year that I saved. They where doing well, but we had a wet winter. The water drained away from the base of the tomatoes. But recently, I noticed that the tomato plants started to get yellow leaves, then brown. Then they dropped the green leaves. The plants never got better so I pulled them up.
After studying them, I believe the plants contracted either fusarium wilt
or verticillium wilt
. Here is my question: will it spread? How can I get rid of these two funguses?
A. To date, there is no chemical treatment available for fusarium wilt and verticillium wilt.
- Destroy infected plants immediately.
- To slow the diseases, keep soil pH between 6.5 and 7.0 and use a nitrate-based nitrogen fertilizer rather than an ammonia-based nitrogen fertilizer.
- Avoid planting other Solanaceous crops (potato, pepper, and eggplant) in the same area, too – they are susceptible to the fungus.
- At the end of the season, set dry leaves or straw on affected area. Burn to kill fungus in the soil.
- Rotate crops.
