Research

Fungicide programs for control of early leaf spot of peanut in Georgia typically consist of a full-season program that includes seven applications made on 14-day intervals. Field tests were conducted to compare full-season and reduced programs. Reduced programs of pyraclostrobin resulted in final levels of leaf spot that were similar to or lower than those in plots receiving a full-season program with chlorothalonil. Yields of reduced programs with pyraclostrobin were similar to those of full programs of either chlorothalonil or pyraclostrobin.
