New watermelon disease discovered in Florida in 2013 causes severe blighting and yield loss of 5-15% in ~6,500 acres. The disease, caused by novel strains of Pseudomonas syringae, spread to Georgia and other southeastern states in 2014, leading to increased bactericide costs. Current research aims to develop an Integrated Pest Management (IPM) strategy using healthy transplants, acibenzolar S-methyl, biological control agents, and copper + ethylene bis dithiocarbamates. Field trials will be conducted in 2015, with results presented at key agricultural meetings. Funding requested: $15,000 for one year. Lead PI: Mathews Paret. Supported by Florida Watermelon Association.
