PARASITICIDAL COMPOSITIONS AND METHODS OF USE

摘要

A solvent system for pyrethroids and pyrethrins comprises a terpene or a terpene derivative such as a terpene alcohol, aldehyde or ketone. In a preferred embodiment, the solvent system further comprises an alkylene glycol ether. Compositions comprising pyrethroids and/or pyrethrins in such a solvent system do not crystallize at cold temperatures and have increased efficacy compared to formulations containing conventional solvents.
