摘　　要：田间试验结果表明,对已发生霜霉病的黄瓜植株,于初花期叶面喷施化学诱抗剂活化酯(50μg／ml),病害发展可得到有效控制。活化酯处理后13d,防治效果达85.8％,发病情况明显减轻;处理后27d,防治效果为78.7％,病害发展得到了有效控制,处理后41d,防效仍可达60.5％。这表明活化酯可以诱导黄瓜产生对霜霉病的抗性,因而能够替代化学农药控制病害,达到无污染、无农药残留、无公害生产的目的。Field trials were conducted on the control of cucumber downy mildcw with acihenzolar. acibenzolar at 50 μg/ml applied at onset of flowering to leaves of cucumber plants already infected with cucumber downy mildew effectively controlled the disease Control reached 86 and 79% at 13 and 27 d after treatment, respectively, and was still at an effective level (61 % ) after 41 d. These results indicate acibenzolar can induce resistance in cucumber to cucumber downy mildew, acibenzolar use thus can substitute for application of a chemical pesticide, thereby preventing pollution, pesticide residues, and associated risk to public health
