RootShield - WP

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.

Using RootShield WP to thoroughly drench the soil protects roots for up to 12 weeks and can cost less than 1 cent per 6" pot when applied properly. Within 24 hours of application, RootShield WP blocks and actively attacks pathogens by releasing enzymes that dissolve the cell wall of pathogens after which the Trichoderma "eats" them. Another benefit of RootShield WP is the 0-hour REI! You will be able to continue your normal work around the growing environment immediately after application.

 

Suggested Uses: Inoculating seed stock, transplants, bulbs, etc. Perfect for soil drenches when preparing growing beds and media. Can be used in chemigation systems. Safe for use on edible crops and ornamentals.
