Abstract/Contents:Responds to frequently asked questions about brown patch in tall fescue. States that brown patch "causes circular patches of brown grass." Also states that as "these patches become more numerous and increase in size, large areas of turf may die." Describes possible symptoms of brown patch, including cobweb like strands of fungus growing on leaf, smoked ring of fungal growth on margins of the patch, and large bluish-gray lesions found on the blades of the grass. States that "brown patch is caused by a fungus called Rhizoctonia solani. States that hot, humid weather encourgaes the development of brown patch. Notes that "conditions within the turf canopy are simply more favorable for disease development in full sun." Mentions cultural practices that may help reduce brown patch. Suggests that "fertilization in late spring and summer almost guarantess that brown patch will be a problem." Also suggests fertilization should be completed before April 15. Explains that fall seeding is preferred to spring season for cool season grasses because "fall seeding allows for two seasons of rapid growth prior to summer heat and drought stress of summer." Recommends fungicides that may be used to control brown patch, including Myclobutanil or propiconazole. Suggests that a cheaper alternative to fungicide application is overseeding damaged lawn turf-type fescue seed.
