Management of Transplant House Spread of <i>Acidovorax avenae</i> subsp. <i>citrulli</i> on Cucurbits with Bactericidal Chemicals in Irrigation Water

Fig. 2. Control of spread of bacterial fruit blotch of watermelon in the transplant house with peroxyacetic acid (PA) in the irrigation water, PA in the irrigation water plus weekly sprays of cupric hydroxide or acibenzolar-S-methyl (ABM), or weekly sprays of cupric hydroxide alone. PA treatments were applied at 80 µg/ml in the daily irrigation water; cupric hydroxide was applied weekly as a 840 µg/ml spray solution; and ABM at 0.05 g/liter was also applied as a weekly spray. Treatments labeled with the same letter on a given date were not significantly different at P = 0.05 by analysis of variance and Duncan’s new multiple range test.
