Note to readers, attached is the complete final report for FNE93-036.
This experiment attempted to measure the ability of peracetic acid to inhibit the fungus Botrytis cinera in raspberry plants when applied to the fruit blossoms. It was conducted during the growing season of 1993 on a farm in Eastern Pennsylvania. The treatment consisted of field applications of four different concentrations (0, 0.5, 1.0, and 3.0 percent) of peracetic solution during the month before harvest stage. The number of raspberries from each treatment group infected with B. cinera was counted and recorded after 24 hours of storage. Although an increased amount of infection in the two intermediate rates was noticed, no relationship was found between the percent of infected fruit and the increase of peracetic concentration. Strawberries that were treated with peracetic acid as a post harvest dip also showed no effect of treatment.
