Treatments with benomyl and UV light were evaluated with regard to the ocurrence of fruit rot of peaches cv. Jade kept under room temperature conditions for 8 days after harvesting. The evaluations were performed at the 4th and 8th days at room conditons (26ºC and 75-80% RH). The treatments were: T1 - control ; T2 - peaches immersed in 0,06% benomyl water solution ; T3 - peaches exposed to UV-C light (3,71kj. m -2) for 10 minutes ; and T4 - peaches exposed for 30 minutes to the UV-C light (11,15kj. m ²). The experiment a 2x4 factorial arrangementa in design was a complete randomized with three replications of ten peaches per plot. The variables evaluated were: total soluble solids (TSS); total titrable acidity (TTA); pH; firmness and incidence of rots. The pH of the peaches did not change during 4 or 8 days they remained at room temperature. The level of TSS and TTA was changed at 4th day, but only the firmness of the fruit had significant differences between treatments at the 8th day at room conditions. The peaches of T2 and T4 treatments had the least incidence of rots. It was concluded that the changes in TSS, TTA, pH and firmness, after 4 and 8 root condition (26ºC and 75-80% RH) due to treatments did not affect the final quality of peaches. The UV-C, 254nm light treatment for thirty minutes controls rot incidence up to 100% after 4 and 8 days in preservation at root condition.
