摘要
为了筛选出适合防治地下害虫的杀虫剂,以甘薯普薯32为试材,在河南郑州和洛阳地下害虫发生严重的地块,研究5种药剂对地下害虫的防治效果.结果表明:0.5％噻虫胺(颗粒)90 kg/hm2和金龟子绿僵菌2亿/g(颗粒)90 kg/hm2,防治效果较好,防治效果最高分别是82.77％和79.48％,商品率最高分别为92.51％和91.06％,平均产量比对照增产最高分别是10.49％和9.57％.噻虫胺和金龟子绿僵菌分别代表化学药剂和生物药剂在甘薯地下害虫防治上表现较好.
Abstract
In order to screen out insecticides suitable for controlling underground pests,sweet potato Pushu 32 was used as the test material to study the control effects of five insecticides on underground pests in severely affect-ed plots in Zhengzhou and Luoyang,Henan.The results showed that 0.5％thiabendazole(particle)90 kg/hm2 and Metarhizium anisopliae 200 million/g(particle)90 kg/hm2 had good control effect,the highest control effect was 82.77％and 79.48％,the highest commercial rate was 92.51％and 91.06％,and the average yield in-creased by 10.49％and 9.57％,respectively,compared with the control.Thiamethasone and Metarhizium aniso-pliae,representing chemical and biological agents respectively,performed better in the control of underground pests in sweet potato.
