Soil Sterilization for Vegetable Gardens: Is It Necessary?

Reader Inquiry

Father wants to "sterilize" 800 sq ft of vegetable gardens with dazomet/basamid, concerned crop rotation isn't effective. Cannot find products locally.

Expert Opinion

Sterilization is rarely needed unless nematodes (on okra) or bacterial wilt (on tomatoes) are confirmed. Dazomet requires a pesticide license and is not available to homeowners. Focus on disease-resistant varieties and good sanitation instead.
