| 摘 要： | 采用盆栽试验研究壳寡糖对茄子棒孢叶斑病的防治效果和减药效果。结果表明,100μg·m L~(-1)壳寡糖喷雾诱导茄子幼苗3次,对茄子棒孢叶斑病具有良好的防治效果,防效达62.56%。防御酶超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CAT)活性均显著提高。100μg·m L~(-1)壳寡糖诱导3次后喷施50μg·m L~(-1)啶酰菌胺与单独喷施100μg·m L~(-1)啶酰菌胺均能显著降低茄子棒孢叶斑病病情指数,且二者防效相当,表明壳寡糖具有明显的减药作用。

| Abstract: | 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. |
