Encapsulated efficacious zinc phosphide rodenticide

摘要

A rodenticide composed of particulate zinc phosphide which has been encapsulated with a layer or coating of a thermoplastic polymer. This polymer coating will inhibit reaction, in the rodent's mouth so that the zinc phosphide will be consumed without the rodent detecting its' presence. However, the coating will allow reaction of the zinc phosphide in the rodent's stomach which will cause the death of the rodent.
