BioWorks Rootshield Plus WP, 3lb

Before you plant, apply OMRI listed RootShield WP (Wettable Powder) to protect plant roots from common soil-borne pathogens. RootShield WP is a certified organic soil inoculant that uses the highly-effective hybrid fungus Trichoderma harzianum, Rifai strain KRL-AG2, to kill Pythium, Rhizoctionia, Fusarium, Thielaviopsis and Cylindrocladium species. Reducing stress and increasing root mass results in healthier growth and larger yields.

RootShield WP is water soluble and allows for easy mixing and application using a variety of spraying equipment. This makes it ideal for drenches in nurseries and greenhouses.
