【摘要】 试验结果表明,3.6%加强型杀虫双GR、3.6%普通型杀虫双GR和8%杀螟丹.辛硫磷GR 3种农药对甘蔗螟虫均有较好的防治效果,其中对螟害枯心率防效均达80%左右,对螟害株率防效均达69%以上;5%辛硫磷GR、3.6%加强型杀虫双GR和5%新型甲拌磷GR 3种农药对金龟子田间残留虫口数防效最佳,防效均达80%以上。它们可作为防治甘蔗螟虫、金龟子的替换农药,田间使用剂量以60～90kg/hm2为宜。更多还原

【Abstract】 Six pesticides were applied to control sugarcane insect pests in the field.The results indicated that three pesticides,3.6% reinforced type bisultap GR,3.6% normal bisultap GR and 8% cartap-phoxim GR can effectively control sugarcane borers,and the control effect of dead heart rate and borer pest rate of sugarcane plants were about 80% and 69%.The control effect of 5% phoxim GR,3.6% reinforced type bisultap GR and 5% phorate GR against residual Holotrichia ovata in the field was up to 80%.The five pesticides can be used as alternative pesticides against sugarcane borers and Holotrichia ovata,and the best application dosage in the field should be about 60-90 kg/ha.更多还原
