Brown patch season will be coming up in turf later in June. The following is a short reminder article.
Brown Patch
This disease, caused by the fungus Rhizoctonia solani, will be starting to develop later in June on turf. To reduce the incidence and severity of brown patch, avoid applying too much nitrogen (e.g., not more than ¼ lb actual N/1000 sq. ft) during hot weather, irrigate between midnight and 8 a.m. to minimize the leaf wetness period, and spray turf now with Armada, Banner (preventive only), Chipco 26GT, chlorothalonil, Compass, ConSyst, Curalan, Disarm, Eagle, Endorse, Headway, Heritage, Insignia, mancozeb, Medallion, ProStar, Spectro, Tartan, thiophanate-methyl, Touche or Tourney per manufacturer’s recommendations.
