4种药剂防治黄芪蚜虫田间药效试验
Efficiency Test of Four Agents against Astragalus membranaceus ( Fisch.) Bge. Aphids
摘要
Abstract
Four agents were selected to control the aphids on Astragalus membranaceus ( Fisch. ) Bunge. They were 1 250 times of 25% pymetrozine SC, 800 times of 20% Baichongjing EC, 3 000 times of 2.5% deltamethrin EC and 4 000 times of 5% acetamiprid EC. The field trial results showed that 2. 5% delta-methrin EC was quick -acting with the control effect more than 90% after one day, while 25% pymetrozine SC and 20% Baichongjing EC had long efficiency with the control effect more than 93% after applied for 7 days. The four agents had no significant effect on the stem diameter of Astragalus membranaceus, but 20% Baichongjing EC had very significant effect on its plant height. In a word, 25% pymetrozine SC and 20% Baichongjing EC were safe and high efficiency to Astragalus membranaceus, and had low toxicity and better environmental compatibility, so they were optimal for controlling Astragalus membranaceus aphids.关键词
