【摘要】 葡萄斑叶蝉是新疆葡萄生产上的重要害虫,田间药效试验表明:25%阿克泰水分散粒剂4000～8000倍和10%吡虫啉可湿性粉剂1500～3000倍,对葡萄斑叶蝉防效高,持效期长,药后7d防效在90%以上,药后21d防效仍在80%以上。48%乐斯本乳油2000～4000倍对葡萄斑叶蝉具有很好的速效性,但持效期短,药后21d防效为47.8%～56.30%。2.5%功夫水乳剂3000～6000倍对葡萄斑叶蝉的防效不高,药后21d防效为40.4%～60.0%。更多还原

【Abstract】 The grape leafhopper, Erythroneura apicalis NaWa, is one of the important pests in vineyards in Xinjiang. The experimental results showed that 25% thiamethoxam WG with 4 000～8 000 times and 10% imidacloprid WP with 1 500～3 000 times were very effective and had long persistent control on grape leafhopper. The control effects were higher than 90% and 80% respectively after 7 days and 21 days of the application. 48% chlorpyrifos EC with 2 000～4 000 times and 2.5% lambdacyhalothrine EW with 3 000～6 000 times gave poor control of grape leafhopper. The control effects were 47.8%～56.30% and 40.4%～60.0% respectively.更多还原
