Rodenticidal compositions comprising a rodenticidally effective amount of an isomer of a 3-substituted-4-hydroxycoumarin rodenticide which is capable of existing in more than one stable isomeric form. The isomer, for example, the trans isomer of brodifacoum, is significantly less persistently retained in the tissues of non-rodent mammalian or avian species likely to consume the composition or poisoned rodent carcasses than other isomers of the same 3-substituted-4-hydroxycoumarin. The compositins are substantially free of such other isomers, e.g., the cis isomer of brodifacoum, thereby reducing the risk to non-target species from accidental ingestion.
杀鼠剂组合物包括一种3-取代-4-羟基香豆素杀鼠剂的异构体,其能够存在于多个稳定的异构体形式中,并含有杀鼠有效量。例如,brodifacoum的反式异构体在非啮齿哺乳动物或鸟类物种的组织中的持久滞留显著低于同一3-取代-4-羟基香豆素的其他异构体。该组合物基本上不含其他异构体,例如brodifacoum的顺式异构体,从而降低了非目标物种误食的风险。
