摘    要:选用10%吡虫啉可湿性粉剂、4.5%高效氯氰菊酯乳油、20%氰戊菊酯乳油、48%乐斯本乳油、3%啶虫脒乳油等杀虫剂于克拉豆Cratylia argentea Benth.花期进行保花比较试验。试验结果表明,4.5%高效氯氰菊酯乳油2000倍液的保花效果最理想,施药后第1天和第3天防效分别为62.6%和71.1%;10%毗虫啉乳油3000倍液的防效次之,第3天的防效也达66.2%;20%氰戊菊酯乳油4000倍液、3%啶虫脒乳油5000倍液和48%乐斯本乳油3000倍液的防效依次为64.2%、53.5%、52.1%。

Abstract:Cratylia argentea Benth.was sprayed in a field trial with 5 different insecticides viz.imidacloprid 10% WP,beta-cypermethrin 4.5% EC,fenvalerate 20%EC,Lorsban 48%EC,and acetamiprid 3% EC to observe protection of the inflorescence during the flowering stage.The result shows that beta-cypermethrin 4.5%EC(1:2 000) produced best control effect(62.6% and 71.1% respectively after 1 day and 3 days of spraying),followed by imidacloprid 10% WP(1:3 000) which had a control effect of 66.2% after 3 days of spraying.The...
