摘要
为筛选出对茶橙瘿螨(Acaphylla theae)防治效果较为理想的替代农药,试验研究15%凯恩乳油和24%帕力特悬浮剂防治茶橙瘿螨效果。结果表明,24%帕力特悬浮剂对茶橙瘿螨具有较好的速效性、持效性,24%帕力特悬浮剂450.0 mL/hm2的防治效果明显高于20%哒螨灵可湿性粉剂300.0 g/hm2,是防治茶橙瘿螨的理想药剂。15%凯恩乳油能在一定程度上控制茶橙瘿螨的种群数量和危害。
In order to find substitute pesticide to prevent and cure Acaphylla theae,trials were conducted to evaluate effects of 24% Chlorfenapyr SC and 15% Indoxacarb EC.The field test results showed that 24% Chlorfenapyr SC had better and quicker effects on A.theae with longer duration,and the control effects of 24% Chlorfenapyr SC at 450 mL / hm2 was significantly higher than that of 20% Pyridaben WP at 300.0 g/hm2.24% Chlorfenapyr SC is an ideal pesticide to prevent and cure A.theae,and 15% Indoxacarb EC can also control populations and damage of A.theae to a certain extent.
