Abstract/Contents: | "Photosensitivity of Rhizoctonia solani AG2-2 LP, a pathogen of large patch disease of zoysia grass, was examined in relation to its mycelial growth in media and formation of infection cushions on leaf blades of turfgrass. Most of AG2-2 LP isolates were apparently more photosensitive than isolates of other AGs of R. solani and other genera. Morphogeneis of the photosensitive isolates was suppressed by light irradiation : growth of mycelia in media and formation of infection cushions on leaf blades of turfgrass. Such a suppression remarkably occurred under light of 450-500 nm wavelength that corresponded to the range of visible from blue to green. These physiological characters may explain why expansion of the large patch is slow-down at the daytime in golf courses. Because light irradiation is effective to reduce infection cushions on both living and heat-killed leaf blades, low-cutting of turf in out-growth seasons may contribute to expose thatch consisting of accumulated dead grasses to sun light, resulting in reduction of infection sources in the next growing season." |
