Disease control in soil-based tomato production using biofumigation and *Trichoderma* spp.

This best practice sheet details strategies for managing corky root rot in tomato production using biofumigation with mustard species and *Trichoderma* spp. biological control. The EcoStack project tested these methods in Swedish organic greenhouses, showing reduced disease severity and improved root weight in some soils. Results highlight variable efficacy depending on soil conditions, emphasizing the need for site-specific approaches. The study supports sustainable disease control by minimizing chemical inputs and leveraging soil microbial communities. Findings from laboratory trials suggest potential for field application, though large-scale validation is needed.
