4种药剂对甘薯地下害虫的防治效果研究

为了有效防治甘薯地下害虫,筛选出防治甘薯地下害虫高效、低毒的药剂,试用70%吡虫啉水分散粒剂、30%毒死蜱微胶囊剂、30%辛硫磷微胶囊剂和3%克百威颗粒剂4种药剂,选择甘薯地下害虫发生较重地块,对甘薯地下害虫的防治效果进行比较。结果表明,4种药剂对甘薯地下害虫的防治均有效,其中处理70%吡虫啉水分散粒剂1.5 kg/hm2和3%克百威颗粒剂45 kg/hm2的防治效果最好,处理30%毒死蜱微胶囊剂15 kg/hm2和30%辛硫磷微胶囊剂15 kg/hm2的防治效果中等。由于克百威残留期长、毒性高,为农业部禁止或限制使用农药,使用70%吡虫啉水分散粒剂1.5 kg/hm2防治甘薯地下害虫相对较好...

In order to screen some both highly effective and lowly toxic pesticides for sweetpotato underground pests control,experiments of four pesticides of 70 % imidacloprid WG,30 % chlorpyrifos microencapsules,30 % phoxim microencapsules and 3 % carbofuran granules were carried out to compare the underground pests control efficacy in sweetpotato fields with heavy damage. The results showed that all four pesticides were effectual. Treatments of 70 % imidacloprid WG（ 1. 5 kg / hm2） and 3 % carbofuran granules（ 45 kg/hm2） had the higher control efficacy,while the treatments of 30 % chlorpyrifos microencapsules（ 15 kg / hm2） and 30 % phoxim microencapsules（ 15 kg/hm2）had medium control efficacy. The carbofuran had characteristics of long residual and high toxicity,and was forbidden or limited use by the Ministry of Agriculture,so the 70 % imidacloprid WG（ 1. 5 kg / hm2） was a better choice for controlling sweetpotato underground pests.
