摘要
为明确5%环虫酰肼SC对水稻二化螟防治效果及使用技术,试验采用茎叶喷雾法防治水稻田二化螟。试验结果表明:5%环虫酰肼SC 1050、1350、1650 mL/hm2,采用二次稀释法,兑水675 kg/hm2,在水稻二化螟低龄幼虫盛期均匀喷雾,同时田间保持3~5 cm水层5~7 d,二化螟为害定型后调查防治效果分别达86.32%、91.01%、95.53%,都显著高于对照药剂1.8%阿维菌素ME 600 mL/hm2的防效,且对水稻和天敌安全。5%环虫酰肼SC持效期长,防治效果好,是防治水稻二化螟的较好药剂。
In order to ascertain the control effect of cyclotebufenozide 5%SC on rice stem borer,the stem and leaf spraying method was used to control Chilo Suppressalis(Walker)in rice field.Cyclotebufenozide 5%SC 1050,1350,1650 mL/hm2 were used to the second instar larvae of Chilo Suppressalis by spraying after the secondary dilution and addition of 675 kg water/hm2 and keep field water in deep 3-5 cm for 5-7 days.The results showed that the control effect of cyclotebufenozide 5%SC 1050,1350,1650 mL/hm2 were 86.32%、91.01%,95.53%respectively at 23 days after treatments which were significantly higher than that of abamectin 1.8%ME 600 mL/hm2 and they were safe to rice and natural enemies.Cyclotebufenozide 5%SC has long lasting effect and good control effect,was a better insecticide for controlling rice Chilo Suppressalis(Walker).
