摘要
为探究不同类型飞防助剂与杀虫剂配伍方式对其防治稻纵卷叶螟Cnaphalocrocis medinalis效果的影响,以杀虫剂、飞防助剂和施药液量为因素设计3因素4水平的正交试验,通过方差分析(analysis of variance,ANOVA)对各因素的显著性水平进行分析,确定对稻纵卷叶螟具有理想防效的配伍方式。结果表明,杀虫剂和飞防助剂对防治稻纵卷叶螟的效果均有极显著影响,施药液量对防治稻纵卷叶螟的效果无显著影响。施药后第15天,杀虫剂选择10%甲维·茚虫威悬浮剂、飞防助剂选择有机硅、施药液量选择30.0 L/hm^(2)的配伍方式对稻纵卷叶螟的防效较好,达84.32%。飞防助剂并非对所有杀虫剂都具有同等增效,其中聚合物助剂对5%氯虫苯甲酰胺悬浮剂的增效显著高于对其他3种杀虫剂的增效,植物油助剂对12%甲维·虫螨腈悬浮剂的增效显著低于对其他3种杀虫剂的增效,有机硅助剂对4种杀虫剂的增效均较好。
In order to explore the influence of different types of adjuvants and pesticides on the control efficacy against rice caseworm Cnaphalocrocis medinalis,this study designed a three-factor,four-level orthogonal experiment on pesticides,adjuvants and spray volume.Analysis of variance(ANOVA)was conducted to analyze the effects of each factor.The results showed that both pesticides and adjuvants had highly significant effects on the control efficacy against C.medinalis,while spray volume had no significant effects.On the fifteenth day after the spraying,10%emamectin benzoate·indoxacard SC and organosilicon adjuvant at 30.0 L/hm^(2) spray volume had better control efficacy,reaching 84.32%.Adjuvants were not equally synergistic to all pesticides.The synergistic effect of the polymer adjuvant on 5%chlorantraniliprole SC was significantly higher than that on the other three pesticides.The synergistic effect of the plant oil adjuvant on 12%emamectin benzoate·chlorfenapyr SC was significantly lower than that on the other three pesticides,and the organosilicon adjuvant had the best synergies on the four pesticides.
