Management of Early Leaf Spot of Peanut as Affected by Fungicide and Date of Spray Program Initiation

Fig. 5. Comparison of full-season programs of chlorothalonil (Chl) and pyraclostrobin (Pyr) initiated ca. 30 days after planting, to reduced programs of pyraclostrobin with initial applications delayed by ca. 14 days (1 spray eliminated) and ca. 30 days (2 sprays eliminated) on leaf spot progress in of peanut. Early leaf spot was predominant in 2003, and late leaf spot was predominant late in the season in 2004. Error bars represent least significant differences at P = 0.05 among fungicides within a time of spray program initiation.
