Calendar and AU-Pnuts Advisory Programs Compared for Leaf Spot Diseases and Rust Control on Peanut in Southwest Alabama

Fig. 3. Rust ratings (1 = no disease; 9 = highest rating with up to 100% leaves affected) on ‘DP-1’ in 2003 and ‘Florida C99R’ in 2005 The experiment consisted of a factorial arrangement of (A) three fungicide programs (chlorothalonil only, azoxystrobin, or tebuconazole) applied by each of (B) four scheduling strategies (although AU-Pnuts called for applications that were identical to the 2-week schedule in 2005). Analysis of variance in 2003 and 2005 indicated significant (P ≤ 0.05) main factor effects with no 2-way interaction effect on rust rating. The same letter above a bar, within a year, indicates treatments that are not significantly different (LSD = 0.6 and 0.6 for fungicide programs; LSD = 0.7 and 0.7 for application schedules; for 2004 and 2005, respectively).
