Trichoderma Biological Fungicides

Trichoderma Biological Fungicides & Organic Growing Options

Compare RootShield and Obtego biological fungicides by microbial composition, formulation and package size. For organic root-disease management, select the exact formulation for the crop, production site and application method on its label.

RootShield WP

Browse 1 lb and 3 lb wettable-powder packages containing Trichoderma harzianum strain T-22. BioWorks identifies the RootShield family for organic use. Review the individual product's label and current organic-use documentation before integrating it into your growing program.

RootShield PLUS

Compare PLUS wettable-powder listings in 1 lb and 3 lb sizes with the separate granular listing. RootShield PLUS combines T-22 with Trichoderma virens strain G-41. BioWorks provides organic-use information for the PLUS formulations; powder and granular application directions differ. Confirm the exact package and formulation before ordering.

Obtego — 5 lb

A two-species Trichoderma formulation to compare with RootShield products. Review the individual listing, label, storage instructions and organic-use documentation rather than assuming that all Trichoderma products have the same uses or status.

Selecting for Organic Disease Management

Use preventive crop-management practices and select a labeled biological fungicide for the intended application. Confirm the exact formulation's suitability and applicable restrictions with your organic certifier. Follow product-specific directions for application, storage and compatibility with other inputs.
