Abstract

In 1999, 2000, and 2001, efficacy of the strobilurin fungicide pyraclostrobin (Headline F500) for the con­ trol of early leaf spot and southern stem rot was com­ pared to that ofstandard fungicide programs on peanut cv. Georgia Green produced under irrigation. When applied at 2 wk intervals in 1999 and 2001, programs that included pyraclostrobin at rates ranging from 0.08 to 0.22 kg ai/ha gave better control of early leaf spot than the recommended season-long chlorothalonil program and were at least as efficacious against this disease as tebuconazole and azoxystrobin. The level of early leaf spot control provided by 0.08 to 0.16 kg ailha of pyraclostrobin applied every 3 wk and by chlorothalonil at the recommended 2 wk interval was similar. In all 3 yr, incidence ofsouthernstem rot on peanuttreatedwith pyraclostrobin alone, tank-mixed with flutolanil, or al­ ternatedwith tebuconazole was Significantlybelowdam­ age levels recorded in plots treated with chlorothalonil alone and was usually comparable to the level ofdisease control obtained with recommended tebuconazole, flutolanil, or azoxystrobin programs. Compared to chlorothalonil alone, yields ofthe pyraclostrobin-treated peanuts were significantly greater in 2000 and 2001 and generally did not Significantly differ from those yields recorded with the tebuconazole, flutolanil, or azoxystrobin programs. Whilepyraclostrobin often gave similar southern stem rot control over a range of treat­ ment intervals, the most consistent yield gains were obtained when this fungicide was applied every 2 wk.
