Management of Early Leaf Spot of Peanut with Pyraclostrobin as Affected by Rate and Spray Interval

A. K. Culbreath, T. B. Brenneman, and R. C. Kemerait, Jr.

October 2002


Field tests were conducted in Tifton and Plains, Georgia, from 1998 to 2000 to determine the efficacy of pyraclostrobin on early leaf spot of peanut, compared to currently-used fungicides chlorothalonil, tebuconazole, and azoxystrobin. Pyraclostrobin at 21-day intervals maintained control of early leaf spot similar to that of currently available fungicides at 14-day intervals, representing potential savings in time, fuel, labor, and equipment costs.
