Occurrence and Control of Brown Patch Disease of Tall Fescue Turf in Shanghai |
| |
| Abstract: | Brown patch disease of tall fescue (Festuca arundinacea Schreb) is caused by the fungus Rhizoctonia solani Kuhn. Its colony is white and turns light brown in the late stage. The fungus develops best under the optimum temperature from 25℃ to 30℃. Two disease occurrence peaks occur in middle late July and early middle September. The experiments both in laboratory and field indicated that the disease could be controlled to a certain degree with five fungicides (Chlorothalonil, Carbendazim, Validamycin, Mancozeb and Thiram). |
