Evaluation of four different combinations of pesticides on controlling two-specific migration insects

以为害钦州市水稻的两大迁飞性害虫第2代水稻稻飞虱、稻纵卷叶螟害虫为防治对象,开展4种药剂组合田间药效试验,结果表明1%阿维.2%氟铃脲EC600倍液加20%烯啶.60%吡蚜酮WG6000倍液和12%阿维.30%毒死蜱EC600倍液加2%吡虫啉.8%噻嗪酮EC600倍液两种药剂组合的防治效果均高于90%,是防治效果理想的药剂组合。

Based on a field experiment of four different combinations of pesticides, this paper presented two ideal approaches to control two-specific 2^nd generation migration insects of rice in Qinzhou, demonstrating that the two combinations that with 1% avermectins·2% fluorine fluid urea EC in 600 times adding 20% olefinic organism ·60% Derby aphid ketone WG 6000 in times and 12% avermectins·30% chlorpyrifos EC in 600 times adding 2% imidacloprid·8% buprofezin EC 600 in times were the ideal combinations, with a control rate higher than 90%.
