摘要
为了筛选防治水稻抗性二化螟的有效药剂,于 2023 年在湖南省涟源市开展了环丙氟虫胺、阿维菌素、金龟子绿僵菌、杀虫单和乙基多杀菌素对水稻二化螟田间防治效果试验.结果表明:参试药剂对二化螟的防治效果存在明显差异,在药后第14、21 天,10%环丙氟虫胺DC600 mL/hm2 和 25%乙基多杀菌素WG180 g/hm2 的防效最佳,显著高于其他处理,说明环丙氟虫胺和乙基多杀菌素均对水稻二化螟具有良好的防效,但二者都具有速效性不高但持效性较好的特点,可与起效快的药剂复配使用,达到更好的防治效果.
Abstract
To screen effective insecticides in the control of resistant rice stem borer(Chilo suppressalis),a field experiment was conducted in 2023 on the control effects of cyproflanilide,abamectin,Metarhizium anisopliae,monosultap,and spinetoram in Lianyuan City,Hunan Province,China.The study showed significant differences in the control effects among the tested insecticides.On days 14 and 21 after insecticide application,the control effects were significantly higher with 10%cyproflanilide DC 600 mL/hm2 and 25%spinetoram WG 180 g/hm2 as compared with other insecticides.Therefore,cyproflanilide and spinetoram were effective in the control of rice stem borer.Both insecticides showed slow action but long duration of effect.They can be used in combination with fast-acting insecticides for better control performance.
