4种杀虫(螨)剂防治橡胶六点始叶螨室内药效试验
|
摘要
用4种杀虫(螨)剂在室内盆栽苗上进行防治橡胶六点始叶螨的药效试验,结果表明4种药剂均对橡胶六点始叶螨有很好的防效,25%阿维菌素·螺螨酯悬浮剂是最好的,高效、速效(药后4 d防效达99.5%以上);22.4%螺虫乙酯悬浮剂和1.8%阿维菌素·高效氯氰菊酯乳油次之(药后12 d达到100%)。4种药剂持效期均较长,长达1个月之久。
Four miticides were used to control Eotetranychus sexmaculatus Riley on Hevea brasiliensis in potted plantlets in the laboratory. The result showed that all tested miticides had good control effect against Eotetranychus sexmaculatus Riley, of which 25% abamectin·spirodiclofen SC was the best one with high efficient and instant effective(up to 99.5% or more of control effect after spraying in 4 days). Then were 22.4% spirotetramat SC and 1.8% abamectin. beta-cypermethrin EC with both 100% of control effect in 12 days. The pesticides effect of four agents would last for more than one month.
