Surfactants are adjuvants that lower the surface tension between two liquids or between a liquid and a solid. Surfactants can improve efficacy of fungicides on crops and could reduce the rate and number of fungicide applications. Combining fungicides and surfactants may increase the efficacy of existing control options. However, since some fungicide-surfactant combinations have been reported to cause phytotoxicity, these compounds should be screened. This is the first year of a two-year study to evaluate commercial surfactants+captan for control of apple fruit rot and phytotoxicity.
