摘要
采用植保无人机和机动喷雾器2种施药方法,开展了氯虫苯甲酰胺、茚虫威2种农药对玉米草地贪夜蛾的田间防效试验。结果表明,采用2种施药械施药对2种农药的田间防效均没有显著差异。200g/L氯虫苯甲酰胺悬浮剂15mL/667m 2药后7d防效最高,植保无人机施药和机动喷雾器施药防效分别为89.0%、91.8%,叶片保护率分别为86.5%、88.3%。150g/L茚虫威乳油18mL/667m 2药后3d防效最高,植保无人机施药和机动喷雾器施药防效分别为85.5%、85.2%,叶片保护率分别为75.8%、76.4%。茚虫威表现出较好的速效性,氯虫苯甲酰胺表现出更长的持效性。
The control efficacy of insecticides chlorantraniliprole and indoxacarb against fall armyworm in maize field were tested using plant protection UAV spraying and mobile sprayer.The results indicated that there was no significant difference between the two treatment methods.The best efficacy of chlorantraniliprole 200g/L SC on fall armyworm,89.0%and 91.8%for plant protection UAV spraying and mobile sprayer,respectively,happened after 7 days of treatment at the dosage of 15 mL/667m 2,with the leaf protection rate of 86.5%and 88.3%,respectively.The best efficacy of indoxacarb 150g/L EC,85.5%and 85.2%for plant protection UAV spraying and mobile sprayer,respectively,happened after 3 days of treatment at the dosage of 18 mL/667m 2 with the leaf protection rate of 75.8%and 76.4%,respectively.The results also showed that the insecticide indoxacarb performed better in quick acting,but chlorantraniliprole did better in long-lasting effective period.
