摘要:

为了研究噻虫胺、金龟子绿僵菌、辛硫磷、球孢白僵菌等药剂不同施用量(60、75、90 kg/hm2)对甘薯地下害虫的防治效果,以甘薯‘烟薯25’为试材,在河南郑州和鹤壁地下害虫发生严重的地块,筛选适合的甘薯地下害虫药剂及施用量。结果表明:4种药剂对‘烟薯25’的防治效果在郑州和鹤壁效果相似,适合‘烟薯25’的化学药剂是0.5%噻虫胺90 kg/hm2,防治效果和商品率最高为86.67%和92.63%,鲜薯产量比对照最高增产14.95%;金龟子绿僵菌2亿/g施用量75 kg/hm2,防治效果较好,防治效果和商品率最高为77.85%和91.45%,鲜薯比对照增产最高为9.52%;球孢白僵菌150亿/g 75 kg/hm2防治效果较好,防治效果和商品率最高为78.03%和91.62%,鲜薯比对照增产最高为10.86%。化学药剂噻虫胺和生物药剂金龟子绿僵菌、球孢白僵菌对‘烟薯25’地下害虫防治效果较好,适合在甘薯种植上进行示范推广。

Abstract:

In order to study the effect of different application rates (60kg/hm2, 75kg/hm2, 90kg/hm2) of thiamethylamine, Metarhizium anisoplariae, phoxium phoxium, Beauveria bassiana and other agents on the control of underground pests of sweet potato, the sweet potato ‘Yanshu 25’ was used as the test material and suitable insecticides and application dosage of underground sweet potato pests were screened in Zhengzhou and Hebi of Henan Province. The results showed that the control effects of the four agents were similar in Zhengzhou and Hebi. The suitable chemical agent was 0.5% thianidin 90 kg/hm2, the highest control effect and commercial rate were 86.67% and 92.63%, and the yield of fresh potato increased by 14.95% compared with the control. The application amount of Metarhizium anisopliae 200 million/g was 75 kg/hm2, and the control effect was good, the highest control effect and commercial rate were 77.85% and 91.45%, and the yield of fresh potato increased by 9.52% compared with control. The control effect of Beauveria bassiana 15 billion/g and 75 kg/hm2 was better, the highest control effect and commercial rate were 78.03% and 91.76%, and the highest yield increase of fresh potato was 10.86% compared with control. The chemical clothianidin and the biological agents Metarhizium anisopliae and Beauveria bassiana have good control effect on the underground pest of ‘Yanshu 25’, which are suitable for demonstration and popularization in sweet potato planting.
