The industry standard for control of Pythium, and Phytophthora
Use Subdue® GR on bedding plants, flowers, perennials, shrubs and other ornamental plants in outdoor landscapes and interiorscapes to control damping-off, downy mildew and root and stem rot diseases caused by Pythium and Phytophthora. Apply either as a soil surface application or incorporate into the soil at the time of seeding and transplanting. When applying Subdue GR to the soil surface, irrigate with enough water to completely wet the root zone after application.
