为了阐明杀虫剂20%阿维·杀单ME对二化螟、稻纵卷叶螟的防治效果及应用前景,进行了水稻田间防效试验。结果表明,每公顷施用20%阿维·杀单ME有效成分270g防治二化螟,施药25d的保苗效果为94.80%,其校正杀虫效果为95.00%;每公顷施用20%阿维·杀单ME有效成分270g防治稻纵卷叶螟,施药25d后的保叶效果为92.83%,施药10d后校正杀虫效果为93.85%,理论产量增长31.3%。 In order to clarify the control effect and application prospect of 20% Avicel ME ME on Chilo suppressalis and Rice Leaf Roller, a field control experiment on rice was conducted. The results showed that the application effect of 20% Avermectin ME was 270g per hectare, the seedling protection effect was 94.80% after 25 days of application, the corrected insecticidal effect was 95.00%; 20% The single leaf active ingredient 270g was used to control the rice leaf roller, the leaf protection effect was 92.83% after 25 days and the corrected insecticidal effect was 93.85% after 10 days. The theoretical yield increased by 31.3%.
