visit turfgrass seed distributors, extension specialists, or visit the National Turfgrass Evaluation Program website at: [www.ntep.org]. If incorporating disease resistant varieties of turfgrass is not an option then focus on better management practices. Some of the management practice include reducing thatch, having adequate drainage, and removing dew during hot and humid weather. Dew can be removed from the grass from mowing, using a backpack blower, or dragging a hose across the grass. Install an internal drainage system if you have severe drainage problems. Improve air circulation and avoid irrigation practices that will leave moisture on the grass blades for extended periods of time. An adequate aeration program will relieve compaction and improve drainage. Aeration should annually disrupt between 15 and 20% of the total surface area. Be sure that you are not applying excess nitrogen to your soil. Most balanced fertility programs for Kentucky Bluegrass lawns will consist of applying two to five lbs of nitrogen/1000 sq.ft. a year. Chemical control If severe enough or on high valued turf (ex. golf greens) summer patch can be controlled with the use of fungicides. The application of fungicides is usually done on a curative basis. Apply fungicides at the very first sign of Brown patch symptoms. In traditionally bad areas that cause severe damage to the turf a preventative fungicide application will work best. Fungicides should be applied according to the instructions on the label, the application of fungicides containing thiophanate-methyl and/or chlorothalonil in weather above 90 °F have been proven ineffective against Rhizoctonia zeae. Minimize the cost of applying fungicides by selecting fungicides that will work on a wide range of turfgrass diseases at the same time. Effective fungicides includes: Benzimidazoles : Pro Turf Carboximides : Prostar DMIs : Banner, Bayleton Dicarboximides : Proturf Fungicide X, Touche Dithiocarbamates : Captan Nitriles : Daconil QoIs : Heritage, Compass, Insignia Antibiotics : Endorse (polyoxin D) Phenylpyrroles : Medallion References Turfgrass diseases
