Abstract Studies were conducted with chitosan‐coated fungicide to find out inhibition effect against C. gloeosporioides and powdery mildews of cucumber. The inhibition effect of chitosan coated fungicide was evaluated in in vitro condition against C. gloeosporioides and the inhibition effect was evaluated against powdery mildews in field condition. Chitosan coated fungicides were provided from Korea University, Seoul. Chitosan coated fungicide Difenoconazole (3,000Da.‐0.3%,W/V, 30,000Da.‐1%,W/V) was applied to powdery mildews of cucumber, and Tebuconazole (3,000Da.‐0.3%,W/V, 30,000Da.‐0.1%,W/V) was applied to pepper anthracnise C. gloeosporioides in in vitro test at the concentration of 1,000 and 1,500 folds. After the treatment of each different fungicides, hyphae of each pathogen was observed by using SEM in the different time intervals of 1, 3, 5, 10, and 15 days after the treatment. The result showed that the coating fungicides have inhibition effect against the hyphae growth of these pathogens.
