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

D. L. Hopkins, C. M. Thompson, and B. Lovic

January 2009


Bacterial fruit blotch (BFB) is a seed-borne disease of cucurbits that spreads rapidly in the warm, humid environment of the transplant house, often resulting in high numbers of infected plants going into the field. The only control options for BFB once it gets into a transplant house are crop destruction or multiple applications of a copper-containing bactericide/fungicide. In this study, various treatments were compared with the standard foliar spray application of cupric hydroxide for BFB control under transplant house conditions.
