| 摘 要： | 为了筛选在西北旱作区针对马铃薯朱砂叶螨的最佳防治药剂, 选择了8种杀螨剂进行两年的田间药效试验。结果表明, 24%螺螨酯悬浮剂(SC)处理下的马铃薯单株块茎数最高, 螨株率最低, 并且叶片SPAD值及光合参数值最高, 8种药剂中, 24%螺螨酯SC、43%联苯肼酯SC、2%阿维菌素SC、11%乙螨唑SC和73%炔螨特乳油(EC)对马铃薯朱砂叶螨防效高于80%, 可作为防治马铃薯朱砂叶螨的药剂。

| Abstract: | In order to select the best control agents for potato Tetranychus cinnabarinus and guide large area control, eight kinds of acaricidal agents were selected for field efficacy test. The results showed that the number of tubers per potato plant was the highest and the rate of plants with mite was the lowest under spirodiclofen 24% SC treatment. SPAD value and photosynthetic value of leaves under spirodiclofen 24% SC treatment were the highest than those under other treatments. Spirodiclofen 24% SC, bifenazate 43% SC, abamectin 2% SC, etoxazole 11% SC and propargite 73% EC had the control efficacies of over 80%, which can be recommended as the control agent against T. cinnabarinus on potato. |
