摘　　要：30%强力杀蚧(Omethoate)微乳剂防治梅园朝鲜球坚蚧DidesmococcuskoreanusBorchs试验结果表明:800,1200倍液药后1～7d的防效均保持在94.5%以上,击倒力强,杀蚧效果快;药效期长,药后14d,防效仍达99%以上;其600,800和1200倍液之间防效差异不明显。600,800和1200倍液的防治效果与25%蚧死净乳油在药后3,5,7,14d的防效有显著差异,25%蚧死净乳油的持效时间均较短,药后3d防效就陆续下降,分别从89.92%降到88.56,81.41%和61.82%。而与40%杀扑磷(速扑杀)乳油相比其防治效果之间无显著差异。30%强力杀蚧微乳剂具有作用速度快,持效期长、对青梅安全性高,防治成本底的特点。The micro-emulsion of 30% Qiang-h-sha-jie（Force kin jie） was used in control of Didesmococcus koreanus in plum orchards. The diluted solution by 800 or 1200 times could control above 94.5 % of the pests in 7 days after use of the insecticide with a high knock-down rate; After 14 day, the effect was stin more than 99% ; There was no significant difference in control effects among treatments with 600, 800 and 1200 times diluted solutions. Comparing with the control effect of 25% Jie-si-jing EC and 40% supracide EC,30% Qiang-li-sha-jie was a good coiee for control of D. koreanus because of its rapid killing speed, long time control effect, and higher safety and lower costs.
