摘　　要：为了筛选薰衣草上土耳其斯坦叶螨的高效防治药剂,本文选用240g/L螺螨酯悬浮剂4000倍液、3.2%阿维菌素乳油3000倍液、16%四螨·哒螨灵可湿性粉剂1600倍液、73%炔螨特乳油2500倍液、0.6%苦参碱水剂1000倍液5种药剂开展防治试验。结果表明,药后1、3d,3.2%阿维菌素乳油防效最高,达到80.02%和90.30%;药后7d,240g/L螺螨酯悬浮剂防效最高,为91.85%;药后15d,240g/L螺螨酯悬浮剂防效较好,为95.23%。240g/L螺螨酯悬浮剂、3.2%阿维菌素乳油、16%四螨·哒螨灵可湿性粉剂、73%炔螨特乳油在0.05显著水平和0.01极显著水平均无显著差异,且最高防治效果均大于85%,建议交替使用。In order to screen the high-efficiency control agents of Tetranychus turkestani on Lavender,240 g/L Spirodiclofen(4000 times),3.2% Avermectin EC(3000 times),16% Clofentezine-pyridaben WP(1 600 times),73% Propargite EC(2 500 times),and 0.6% MatrineAS(1 000 times)were used for prevention and control test.The results showed that 1 d and 3 d after application,3.2% Avermectin EC had the highest control effect,respectively reached 80.02% and 90.30%;7 d after application,the control effect of Spirodiclofen was the highest(91.85%);15 d after application,the control effect of Spirodiclofen was 95.23%.There was no significant differences of control effect among above pesticides at the significant level of 0.05 and the significant level of 0.01,and the highest control effect was higher than 85%.It is recommended to use different pesticides alternately.
