摘要(Abstract)：

【目的】通过田间药效试验评价新型诱导抗病激活剂5%氟唑活化酯EC对西瓜甜瓜白粉病的诱导抗病效果,为合理使用5%氟唑活化酯EC提供依据。【方法】采用叶面喷雾法对西瓜甜瓜进行诱导施药,分别于2016年及2017年在北京顺义杨镇、北京延庆县康庄镇小丰营村及北京市海淀区中国农业科学院蔬菜花卉研究所所区农场3地7个点进行田间西瓜甜瓜白粉病的诱导抗病试验。【结果】综合2 a(年)多的试验发现,5%氟唑活化酯EC对西瓜甜瓜白粉病的诱导抗病效果随质量分数增大有增高趋势,随施药次数增多有增高趋势。对于甜瓜白粉病,100、50和25 mg·kg^(-1)的5%氟唑活化酯EC诱抗效果显著高于杀菌剂40%氟硅唑EC;对于西瓜白粉病,100、50 mg·kg(-1)的5%氟唑活化酯EC诱抗效果显著高于杀菌剂40%氟硅唑EC;对于西瓜白粉病,100、50 mg·kg^(-1)的5%氟唑活化酯EC诱抗效果显著高于杀菌剂40%氟硅唑EC。但100、50 mg·kg(-1)的5%氟唑活化酯EC诱抗效果显著高于杀菌剂40%氟硅唑EC。但100、50 mg·kg^(-1)质量分数下有药害问题,产量也会受到影响。5%氟唑活化酯EC在质量分数为10 mg·kg(-1)质量分数下有药害问题,产量也会受到影响。5%氟唑活化酯EC在质量分数为10 mg·kg^(-1)、诱导5次、诱导间隔期7 d条件下,对西瓜白粉病的诱导抗病效果最好,为97.5%,与对照诱导抗病激活剂苯并噻二唑(BTH)及杀菌剂42.8%氟菌·肟菌酯悬浮剂无显著差异。5%氟唑活化酯EC在质量分数10 mg·kg(-1)、诱导5次、诱导间隔期7 d条件下,对西瓜白粉病的诱导抗病效果最好,为97.5%,与对照诱导抗病激活剂苯并噻二唑(BTH)及杀菌剂42.8%氟菌·肟菌酯悬浮剂无显著差异。5%氟唑活化酯EC在质量分数10 mg·kg^(-1)、诱导5次、诱导间隔期7 d条件下,对甜瓜白粉病的诱导抗病效果最好,为63.89%。5%氟唑活化酯EC在质量分数10 mg·kg(-1)、诱导5次、诱导间隔期7 d条件下,对甜瓜白粉病的诱导抗病效果最好,为63.89%。5%氟唑活化酯EC在质量分数10 mg·kg^(-1)、诱导5次、诱导间隔期7 d条件下,对西瓜白粉病的诱导抗病效果最好,为69.16%。【结论】5%氟唑活化酯EC对西瓜甜瓜白粉病有较好的诱导抗病效果,其最佳诱导质量分数为10(-1)、诱导5次、诱导间隔期7 d条件下,对西瓜白粉病的诱导抗病效果最好,为69.16%。【结论】5%氟唑活化酯EC对西瓜甜瓜白粉病有较好的诱导抗病效果,其最佳诱导质量分数为10²5 mg·kg25 mg·kg^(-1),最佳诱导次数为5次,可以取代杀菌剂施用,效果与BTH等同。
