为了寻找防治咖啡虫害的高效低毒药剂,以24%螺虫乙酯SC为试材,进行了田间试验。结果表明:24%螺虫乙酯SC对咖啡根粉蚧和咖啡绿蚧有良好的防治效果,药后60天对咖啡绿蚧的防效显著优于对照药剂48%毒死蜱和40%杀扑磷;对咖啡根粉蚧的防治效果虽然低于对照药剂48%毒死蜱,但也有一定的防效,在第二次施药后30天,24%螺虫乙酯SC 3 000倍液的平均防效可达76.29%;且与对照药剂相比,24%螺虫乙酯SC的药效持续时间显著长于对照药剂。采用24%螺虫乙酯SC防治咖啡害虫,简单易行、省时省力、节省成本,是一种简化、高效的虫害防治措施,可以广泛推广。
In order to find efficient and low toxicity agents for controlling coffee insects, a field experiment was conducted with 24% spirotetramat SC as test material. The results showed that 24% Spirotetramat SC had good control effect on mealybug and mealybugs. After 60 days, the control effect was significantly better than that of 48% chlorpyrifos and 40% ; Although the control effect of mealybugs was lower than that of 48% chlorpyrifos, it also had some control effects. At 30 days after the second application, the average control effect of 24% spirotetramate SC 3000 times Up to 76.29%; and the efficacy of 24% spirotetramat SC was significantly longer than that of the control. The use of 24% Spirotetramat SC to control coffee pests is simple, time-saving, labor-saving and cost-saving. It is a simple and effective pest control measure that can be widely promoted.
