几种内吸药剂对烟蚜的室内毒力及田间防效
|
摘要
为了明确常用内吸药剂对烟蚜的室内毒力及田间防治效果,为烟蚜的有效防控提供理论依据,本研究采用浸根法测定了6种内吸药剂对烟蚜的室内毒力及田间防效。室内毒力测定结果表明,10%吡虫啉可湿性粉剂和2%噻虫啉悬浮剂优于对照药剂25%噻虫嗪水分散粒剂的室内毒力,相对毒力倍数分别为7.23和3.87。田间药效试验表明:25%噻虫嗪水分散粒剂2 000倍液、3 000倍液和22.4%螺虫乙酯悬浮剂2 000倍液、3 000倍液、4 000倍液和2%噻虫啉悬浮剂2 000倍液、3 000倍液、4 000倍液以及48%噻虫胺悬浮剂4 000倍液浸根处理后,更正防效达98%以上。因此,在生产上可作为防治烟蚜的首选药剂。
To provide theoretical basis for effective control of Myzus persicae, the laboratory toxicity and field efficacy of six systemic insecticides on Myzus persicae were evaluated by root-dipping method. The laboratory toxicity test results showed that 10% imidacloprid WP and 2% thiacloprid suspension were superior to the control agent as 25% thiamethoxam water dispersible granules, and the relative toxic multiples were 7.23 and 3.87, respectively. The field efficacy test results showed that after 25% thiamethoxam water dispersible granules diluted for 2 000 and 3 000 times, 22.4% spirotetramat suspension and 2% thiazoline suspension diluted for 2 000、3 000 and 4 000 times, and 48% clothianidin suspension diluted for 4 000 times,they were used for dipping root, repectively, and their control effects were corrected to be more than 98%. Therefore, they were the first choices for prevention and control of Myzus persicae in production.
