摘要
比较了新近推出的新型杀虫剂莫比朗、吡虫啉和速扑杀防治柑桔矢尖蚧的效果。药后1周,3%莫比朗乳油和40%速扑杀乳油1000倍的防效相似,分别达到9609%和9712%,大大高于这两种药的其它参试浓度和10%吡虫啉可湿性粉剂各浓度的防效。药后2周,它的防效仍达90%以上,与40%速扑杀乳油1000倍效果相当。鉴于柑桔矢尖蚧发生代数多,每代发生期长,使用莫比朗防治时,药后14天应再次施药。
Comparison of control efficacy against citrus arrowhead scale among 3% Mospilan EC (acetamiprid),10% imidacloprid WP and 40% Supracide EC was done in 1998.The efficacies of control of 3% Mospilan EC at 1000x and 40% Supracide EC at 1000x were similar,respectively as 96.09% and 97.12%,much higher than those of other test concentrations of these two pesticides and all test concentrations 10% imidacloprid WP.The efficacies of 3% Mospilan EC at 1000x and 40% Supracide EC at 1000x 14 days were still higher than 90% after first application.Considering that there are several generations of citrus arrowhead scale in a growth season of citrus and each generation persists for long time,another application of 3% Mospilan EC should be suggested 14 days after first spraying it to make complete control.
