【摘要】 用3种化学药剂与5种增效剂混配,进行葡萄斑叶蝉的田间药效试验。结果表明,3种杀虫剂吡虫啉、阿克泰和吡蚜酮混配渗展宝(SZB)、菲蓝(FL)、一可佳(YKJ)、杰效利(JKL)、弹指间(TZJ)5种增效剂可延长持效期,减少药剂的施用量。吡虫啉与菲蓝混配制剂药后14 d效果较好,阿克泰与渗展宝、菲蓝、弹指间混配药后的14 d防效均为100%;吡蚜酮与菲蓝、渗展宝混配制剂药后7 d的防效100%。所有增效剂与杀虫剂混用后均比单独使用效果得以提升。更多还原

【Abstract】 The mixtures of three low toxicity pesticides with five synergists were used to control Erythroneura apicalis Nawa in vineyard.The result indicated that all of the mixtures had longer effective duration against the insect and reduce the pesticides application.The mixture of imidacloprid with FL showed better effect than the mixtures of imidacloprid with the other synergists after 14 days of spraying.The mixtures of thiamethoxam with SZB,FL and TZJ had good effects also,and their control effects could be 100% after 14 days.The mixtures of pymetrozine with FL,SZB showed a 100% control effects after 7 days after spraying.All the mixtures had better effects than pesticides used singly更多还原
