説明
Survival of Rhizoctonia solani AG2-2 IIIB causing brown patch disease was investigated in creeping bentgrass. Although the frequency of isolation was not high, isolates of R. solani AG2-2 IIIB were recovered from plants when the disease was not apparent. Furthermore, when symptomless sod samples collected before and after the disease became evident were incubated under high temperature and humidity, severe symptoms of brown patch were observed. The results suggest that the fungus survives persistently and that the disease develops if climatic conditions and host susceptibility favor the pathogen. Sclerotia were frequently observed on the basal parts of the sheath showing brown patch symptoms and were competent as inoculum even if collected from creeping bentgrass after fungicide application. The R. solani AG2-2 IIIB isolates were not isolated from thatch when there was no disease, and the frequency of isolation was low even from diseased thatch. Therefore, the sclerotium is considered to be a survival structure in bentgrass turf.
