Efficacy of Ethanol in Postharvest Benomyl-DCNA Treatments for Control of Brown Rot of Peach

Abstract

Ethanol at concentrations ≥30% improved the efficacy of benomyl-DCNA mixtures in 1-min dip treatments for control of postharvest brown rot in peach. The model of the regression analyses was significant (P≤0.01) and linear first=0.97). The slope of the equation for the incidence of brown rot and the concentration of ethanol with fungicide was similar, but the Y intercept and midpoint values were lower than when ethanol was used alone. Control of brown rot was best with 70% ethanol, but shriveling of fruit epidermis from dehydration was greatest at this concentration (...)
