This application is a broad spectrum fungicide with both systematic and foliar effects to control disease in established turf. It treats/ prevents dollar spot, anthracnose, red thread, fusarium blight, rust, brown patch and mildew. We have two methods of application, soil injection or surface 'fogging', dependant on the type of fungus we are treating for. To help prevent disease and fungi you can raise mower blades to a high level (at least 3") and if seeding bluegrass, add a mix of 20% rye grass as well to reduce susceptibility. Finally, be careful to not excessively water ( not usually a concern in the Billings area, we recommend 30 to 45 min a zone approximately 3 times a week).
