| Abstract/Contents: | "Summer Patch is caused by the root-infecting fungi Magenporthe poae. Plants become infected with M. poae during mid to late spring--when soil moisture is relatively high and soil temperatures reach 60-65 degrees F (15-18 degrees C). Under these conditions, the fungus colonizes and damages turf root systems, while the plants remain asymptomatic. Roots and rhizomes thus damaged typically will turn brown and brittle as the disease progresses underground - without causing any apparent above-ground syptoms. The infection can persist in damaged roots and rhizomes--acting as a re-infection for years. The use of quick-release forms of fertilizers also enhances symptoms of Summer Patch. Using sulfur-coated urea fertilizers, instead of cold water soluble fertilizer sources of nitrogen, can reduce Summer Patch damage by an average of 35% during the peak period of July through mid-September." |
