摘要: 为明确不同施药方法对宿根蔗螟虫的田间防治效果,于2019—2020年采用叶面喷雾、蔗蔸喷雾、土壤沟施和蔗蔸淋灌4种不同的施药方法进行30%氯虫·噻虫嗪悬浮剂防治宿根蔗螟虫的田间药效试验。结果表明,蔗蔸淋灌对甘蔗苗期和收获期螟虫均有良好的防治效果,还可增加甘蔗有效茎数,提高甘蔗产量,2年蔗茎平均产量比空白对照增产29.46%;叶面喷雾和蔗蔸喷雾方法对甘蔗苗期螟虫的防治效果显著,但对收获期螟虫的防治效果不显著,叶面喷雾和蔗蔸喷雾2年蔗茎的平均产量分别比空白对照增产15.58%、9.08%;而土壤沟施处理防治甘蔗螟虫的产量与空白对照的差异不显著。生产上防治宿根蔗螟虫,根据实际情况可采用蔗蔸淋灌、叶面喷雾和蔗蔸喷雾方法进行施药,以蔗蔸淋灌效果最好。

Abstract: In order to clarify the field control effects of different insecticide application methods on ratoon sugarcane borers, the field efficacy test of 30% chlorantraniliprole·thiamethoxam SC on ratoon cane borers with four different application methods including foliar spray, spraying cane stump, applying at soil furrow and drenching irrigation at cane stump were conducted in 2019 and 2020. The results showed that spraying cane stump had better efficacy on controlling sugarcane borers at the seedling and harvest stage of sugarcane, and could increase the number of effective cane stems and the yield of sugarcane. The average yield of sugarcane in two years increased by 29.46% compared with the control without any insecticide. There were significant differences on controlling sugarcane borers of foliar spay and spraying cane stump at seedling stage, while there were no significant differences at harvest stage. The average yield of sugarcane in two years of foliar spay and spraying cane stump increased by 15.58% and 9.08%, respectively, compared with the control without any insecticide. However, there was no significant difference in the yield of sugarcane between the treatment of applying at soil furrow to control borers and the control without any insecticide. According to the actual situation, drenching irrigation at cane stump, foliar spray and spraying cane stump could be used to prevent and control the ratoon sugarcane borers, and the effect of drenching irrigation at cane stump was the best.
