30阿维·灭幼脲悬浮剂防治梨大食心虫田间药效试验

摘要

Aqueous solution of 30% abamectim dimilim SC was used to control pear big borer in field. The results showed that the efficacies of the solution diluting 1 000 times and 2 000 times of 30% abamectim dimilim SC was equivalent to effecacy of the control and better than the 3 000 times dilutions. It was safe compared with CG and it could be recognized as the ideal pesticide against the pear big borer.%　　以30%阿维·灭幼脲悬浮剂为试药，对梨大食心虫进行田间防效试验。结果表明：30%阿维·灭幼脲悬浮剂2000×稀释液、1000×稀释液防治梨大食心虫有较好的速效性和持效性，与对照药剂处理相当，好于3000×稀释液处理。30%阿维·灭幼脲悬浮剂不产生药害，是防治梨大食心虫的理想药剂。
