介绍了田间试验中阿维菌素及其混剂对棉花棉铃虫、柑桔红蜘蛛、蔬菜甜菜夜蛾理想的防治效果。即 :1 .8%阿维菌素EC80ml/ 667m2 ,药后 7d对棉铃虫的防效达 90 %以上 ,保蕾铃效果在 89.5%左右 ;0 .9%阿维菌素EC50 0 0倍 ,药后 3d对柑桔红蜘蛛的防效为 92 .9% ,略高于化学药剂 1 5%哒螨酮EC30 0 0倍的防效 (90 .8% ) ;1 .2 %高渗阿维·高氯EC4 2~53ml/ 667m2 ,药后 5~ 7d对甘蓝甜菜夜蛾的防效均在 90 %左右 ,比两单剂 0 .9%阿维菌素EC50ml/ 667m2 和 4 .5%高效氯氰菊酯EC4 5ml/ 667m2 高出 2 .7%~ 5.7% ,有明显的增效作用 ,并能提高初效。
The ideal control effect of abamectin and its mixture on cotton bollworm, citrus red spider and vegetable beet armyworm was introduced in the field experiment. That is: 1.8% abamectin EC80ml / 667m2, 7d after the treatment of cotton bollworm control effect of more than 90%, Paul Lei effect of about 89.5%; 0 .9% abamectin EC50 0 times, The control efficacy of citrus spider mite on the 3rd day was 92.9%, slightly higher than that of the control drug 100% of pyridaben 150% (90.8%); 1.2% · High chlorine EC4 2 ~ 53ml / 667m2, 5 ~ 7d after the drug beet armyworm control efficiency of about 90%, two single-dose 0.9% abamectin EC50ml / 667m2 and 4.5% efficient Cypermethrin EC4 5ml / 667m2 higher than 2.7% to 5.7%, a significant synergistic effect, and can improve early effect.
