BioWorks’ biofungicide RootShield PLUS now OMRI listed

BioWorks is pleased to announce that the Organic Materials Review Institute (OMRI) has reviewed the company's EPA registered biological fungicide RootShield® PLUS (both Granules and WP), and approved the products for use in organic production.

RootShield PLUS contains two active ingredients: Trichoderma harzianum strain T-22, and Trichoderma virens strain G-41, and provides preventative control of soilborne Phytophthora, improved control of hot-season Pythium (P. aphanidermatum), as well as other prevalent root diseases caused by Rhizoctonia, Fusarium, Pythium, Thielaviopsis, and Cylindrocladium.

RootShield PLUS protects against damaging fungi by growing on roots, inhibiting and actively attacking pathogens; ensuring uninterrupted plant growth for up to 12 weeks per application.

Both the Granules and WP formulations have low Restricted Entry Intervals (REI), 0-day Pre-Harvest Intervals (PHI), and are registered for indoor and outdoor root disease control in greenhouse and outdoor ornamentals, herbs, and vegetables. The products are available in most states.
