2: Greenhouse Usage Recommendations
As a core product for soil treatment: Apply Trichoderma harzianum by hole application or root drenching before planting or transplanting to establish a protective root layer and prevent soil-borne diseases.
Avoid using chemical pesticides: Trichoderma harzianum is a live fungus; avoid using chemical fungicides 3-5 days before and after application to prevent affecting its colonization.
Compatible with natural enemy products: Trichoderma harzianum is safe for predatory mites, parasitic wasps, and other natural enemies, allowing for seamless integration with integrated pest management (IPM) strategies.
Suitable for prevention, not good at emergency treatment: Trichoderma harzianum is mainly for prevention. Once the disease breaks out severely, it needs to be quickly suppressed with chemical pesticides before Trichoderma can be used to restore the soil microbial community.
