Abstract: Biocontrol effects of benzothiazole (BTH) and Bacillas subtilis B1 tagether treatment or respective treatment on major postharvest diseases of muskmelon were studied. The results indicated that all treatments decrease the infection incidence of A. alternata, R.stolonifer, F. semitectum. B1 and BTH or only B1 treatment inhibits the lesion diameter of T.roseum signifcantly. For A.alternata, B1 and BTH or BTH treatment is optimal. B1 and BTH or B1 treatment inhibits the lesion diameter of R.stolonifer signifcantly. B1 and BTH treatment is optimal for F. semitectum. The results also showed that B1, BTH, B1 and BTH significantly induce the peroxidase (POD) activity and chitinase (CHT) activity of muskmelon compared with control. The activity sustaines for at least 8 days at room temperature.

Key words: postharvest diseases, biocontrol, peroxidase (POD), chitinase (CHT)
