Interpretive Summary: This experiment was conducted inTifton, Georgia to evaluate the phytotoxicity of acibenzolar on fresh market bell peppers in 2012 for the control of bacterial spot. Five broadcast foliar applications were applied on a 6-8 day schedule beginning on 2 Apr and ending on 29 May 2012. On 2 and 17 Apr all treatments received 1.0 oz/A and 0.5 oz/A respectively. For the remaining three applications, the following rates were applied: 0.25 oz/A for the 1x, 0.5 for 2x, and 0.75 for the 3x. Phytotoxicity was evaluated on 3 and 24 May and 14 Jun 2012 using a scale of 0-10 (0 = no injury and 10 = dead plants). Fruits were harvested from randomly chosen plants on 29 May and 14 Jun 2012 with the number and weight of marketable fruits determined. No phytotoxicity was observed on the plants for any of the treatment rates (0 for all ratings). No stunting, fruit finish injury, or foliage injury was observed. There were no differences among the treatments or the control in yield of fruit according to weight or number.
