含有单一活性组分的杀虫剂, 在害虫防治上连续使用, 容易使害虫产生抗药性。 通过两 种活性组分的杀虫剂按一定比例混配成混合组分, 往往可以提高防效, 减少有效成分的用量, 节约成本, 同时可以延缓害虫抗药性的产生。
尽管现有技术中泛泛公开了化合物 A 或其同系物同其他杀虫剂混用可以产生附加的优 点和效果, 但含有化合物 A的二元活性组分的杀虫剂组合物的技术方案未见具体公开。 发明内容
本发明目的在于开发一种含有化合物 A 的二元活性组分的、 具有杀虫活性的协同组合 物, 以满足农业、 林业以及卫生领域防治害虫方面对杀虫剂效果日渐提高和品种不断更新的 需求。
人们总是期望在保证有效的害虫防治的同时, 能够减少释放到环境中的化学物质的量。 发明人在研究大量化合物 A的二元活性组分的杀虫剂组合物的基础上, 意外发现了化合物 A 与大环内酯类杀虫剂或茚虫威的组合物在适宜的配比条件下具有协同效应, 表现了出人意料 的优秀的害虫防治效果, 从而完成了本发明。
本发明的技术方案如下:
一种具有杀虫活性的协同组合物, 含有 (a)和 (b)两种活性组分, 活性组分(a)选自 化合物 A, 活性组分 (b) 选自大环内酯类杀虫剂或茚虫威;
所述的化合物 A具有如下结构:
Figure imgf000002_0001
作为本发明的组合物中的活性组分 (b) 的大环内酯类杀虫剂选自以下任意一种: (M ) 阿维菌素 (Abamectin)、 (b2)甲氨基阿维菌素苯甲酸盐 (Emamectin benzoate简称甲维盐)、 (b3 ) 多杀菌素 (Spinosad)、 (b4) 乙基多杀菌素 (Spinetoram)、 (b5 ) 埃玛菌素 (Emamectin) 或 (b6) 弥拜菌素 (Milbemectin)等。
当活性组分 (b) 选自 (b7 ) 茚虫威 (Indoxacarb) 时, 所述的茚虫威既可以是其 S体与
R体的混合物 (例如 75%S异构体与 25%R异构体的混合物、 有效成分以 S异构体计) , 也 可以是精茚虫威 (100%S异构体)。
组合物中两种活性组分的重量份数比为 1 :99~99: 1。
本发明优选的技术方案为: 活性组分 (b ) 选自 (bl ) 阿维菌素、 (b2) 甲维盐、 (b3 ) 多杀菌素或 (b7 ) 茚虫威; 两种活性组分的重量份数比为 1:20~20:1。

室内生物活性测定
实施例 22 含有化合物 A的组合物对小菜蛾的协同作用测定
供试对象: 小菜蛾 PluteUa xylosteUa) , 2龄幼虫, 室内伺养的敏感品系。
测试条件: 温度: 24〜26 °C, 湿度: RH 60%, 光照: L:D=14: 10
试验方法: 采用浸渍法进行处理, 将温室栽培的甘蓝叶取回, 制成直径 2cm叶碟, 将叶 碟在药液中浸渍 5s, 取出后阴干, 放入垫有滤纸的 9cm培养皿中, 挑选整齐一致的试虫接入 培养皿中, 每处理重复 4 次。 将处理后的试虫置于观察室内, 定期观察试虫反应情况, 48h 后调查死、 活虫数, 计算死亡率。
评价采用 Bliss法, 该方法是评价混剂作用的经典方法之一。 Bliss根据其提出的独立联 合作用概念认为, 杀虫剂混用时的理论死亡率 P可用下式来计算:
P =Pm + Pn (l-Pm)
Pm为第一活性组分在浓度为 m时靶标的死亡率 (%); Pn为第二活性组分使用浓度为 n 时靶标的死亡率 (%)。 如果两种活性组分在以一定浓度混合后靶标的实际死亡率大于理论死亡率 P, 则判定两 种活性组分在设定浓度下混合使用具有增效作用, 反之则为拮抗作用。
测试结果见表 1。
