| 摘 要： | 以空白处理为对照，研究不同药剂处理对甘蔗经济指标及抗虫性的影响。结果表明，经药剂处理的甘蔗枯心率、蓟马为害株率、螟虫蛀茎率均显著低于对照，其中5％棵棵无损及新型棵棵无损的防治效果好于其他药剂处理；甘蔗的有效茎数、株高、公顷有效茎数、产量及产糖量在药剂处理条件下均显著高于对照，其中公顷产量及产糖量在5％棵棵无损及新型棵棵无损处理条件下均显著高于其他药剂处理；5％新型棵棵无损在甘蔗上的甲拌磷残留量小于0．01mg／kg，低于EPA（美国环保局）和我国规定的MRL值。因此，生产上可改用5％新型棵棵无损防治甘蔗虫害，以达到防治虫害及增产、增糖的目的，推荐剂量为67．5kg／ha，在甘蔗种植时一次施完。 |

| Abstract: | The present study was conducted to study the effects of different pesticides treatments on economic indices and insect resistance of sugarcane, the control was treated without pesticide. The results revealed that the rates of withered inner leaf, plants damaged by rice thrips and diseased stalks by borer were significantly lower than those of the control, and controlling effects of 5% ＂kekewusun＂ and 5% new pesticide type ＂kekewusun＂ were better than those of other treatments. The number of effective settlings, plant height, number of effective stalks per hectare, cane yield and sugar yield of sugar- cane were all higher than those of the control, especially the cane and sugar yields of sugarcane treated by 5% ＂kekewusun＂ and 5% new pesticide type ＂kekewusun＂ were significantly higher than those of other treatments. The phorate residue of 5% new pesticide type ＂kekewusun＂ in sugarcane was less than 0.01 mg/kg, which was below the MRL value （0.05 mg/kg） specified by EPA and China. In conclusion, the application of 5% new pesticide type ＂kekewusun＂ （recommended dose 67.5 kg/ha, fertilize once） could control insect pest and improve cane yield and sugar productivity sugarcane. |
| Keywords: | sugarcane 5% new pesticide type ＂kekewusun＂ pesticide effect test |
