| Abstract/Contents: | Bentgrass thinning, poor growth, and even death following extended periods of hot weather has been given the name of black layer, or summer decline. The tops of the plants look normal in early stage of the disease, but the roots are weak or have died. The root-rot-type fungi, Pythium graminicola, have been found in 90-100% of the bentgrass plants sampled during all times of the year. These fungi apparently do not cause much disease unless the roots are weakened by environmental stresses such as excessive soil moisture or dry wilt. Indications of disease and possible treatments for it are discussed. |
