ALKYLPHOSPHINES AS PESTICIDAL AGENTS

摘要

A method for controlling pests comprising administering to them a compound of the formula (i) R-PH-R', wherein R is a C1-C6 aliphatic hydrocarbyl group and R' is H or a C1-C6 aliphatic hydrocarbyl group. Either hydrocarbyl group may be optionally substituted. Preferably, the compound of formula (i) is methylphosphine. The method has particular utility against insects which are resistant to phosphine. Also disclosed are pesticidal compositions of compounds of formula (i), and methods and compositions combining these compounds with phosphine.
