摘要
以甘薯品种红香蕉为试材,在地下害虫危害较重地块,研究了地蚜灵、70%吡虫啉粉剂、30%毒死蜱微胶囊剂和白僵菌1号对甘薯地下害虫的防治效果。结果表明:地蚜灵(666.7m2用量,下同)100.0 g、30%毒死蜱微胶囊剂0.5、1.0 kg处理的防治效果较好,防效分别为43.38%、37.37%和41.13%,三者之间差异不显著,均显著高于其它处理。各药剂处理对薯块商品率影响差异显著,对鲜薯产量影响差异不显著。
Using sweetpotato variety Hongxiangjiao as material,the control effects of Diyaling,70% imidacloprid WP,30% chlorpyrifos MC and beauveria 1 on sweetpotato underground pests were examined in plots with heavy damage. The results showed that the control effects of 100. 0 g Diyaling,0. 5 kg and 1. 0 kg 30%chlorpyrifos MC per 666. 7m2were better with the control effect value of 43. 38%,37. 37% and 41. 13% respectively. There was no significant difference among them,which were all significantly higher than those of other treatments. The effects of different pesticide treatments on commodity rate of tubers were significantly different and those on fresh potato yield were not significantly different.
