I have had a disease on my tomatos the last two years that looks like vermiculim wilt. I rotate my plants over 3 years. I understand that earthworms can reduce the fungus in the soil. Do you have any other recommendations?
Grama Pam’s Answer:
Biozome is one of your best bets. It’s a microbe that competes with all fungi except mycorrhizae which for some reason cohabitates with them just fine. This little bugger actually eats petroleum base products.
Keep in mind this is not silver bullet. I use it every fall after I clean up my beds and get them ready for cover crops, then again in the Spring in the planting holes. This has greatly reduced my fungal problems and deepened my soil significantly because of it’s super composting abilities.
Several university sites have other ideas for hygiene. The sure fire solution is to plant resistant varieties. Hope this helps and thank you for growing organically.
