Benzo (1, 2, 3)-thiadiazole-7-carbothioic acid S-methyl ester (BTH) is a novel synthetic elicitor capable of inducing disease resistance in many plants. Fruits were dipped in BTH at 100 mg/L for 10 min, and then stored at room temperature (22 ± 2°C, relative humidity 55-60 %). The results showed that BTH significantly (P \ 0.05) reduced the lesion area of fruits inoculated with Trichothecium roseum and the natural disease incidence of fruits during storage at room temperature. The treatment effectively maintained cell membrane integrity and decreased the production of lipid peroxidation and malondialdehyde. BTH treatment markedly enhanced the accumulation of hydrogen peroxide, (H 2 O 2 ) while decreased the rate of superoxide anion (O 2 Á-) production. Furthermore, BTH observably increased the activities of NADPH oxidase (NOX, EC1.6.3.
