This paper studied the effect of oligosaccharide on controlling eggplant Corynespora leaf spot
and reducing the dose. The results indicated that spraying oligosaccharide with 100 μg·mL-1 concentration for 3
times,the controlling effect on eggplant Corynespora leaf spot was pretty good,and the control effect was up to
62.56%. The activities of SOD,POD and CAT were obviously increased. After spraying oligosaccharide with 100
μg·mL-1 concentration for 3 times,then spray boscalid with 50 μg·mL-1 concentration,the control effect was
similar to that of only spraying boscalid with 100 μg·mL-1 concentration. Both methods could obviously reduce the
disease index of eggplant Corynespora leaf spot,and the effect of reducing the dose was obviously observed.
