Loss of Bioresmethrin, Carbaryl and <i>d</i>-Fenothrin on Wheat during Storage

Abstract

Loss of bioresmethrin, carbaryl and d-fenothrin from post-harvest application to wheat was related quantitatively to wheat temperature and equilibrium relative humidity. Coapplication with piperonyl butoxide increased the stability of bioresmethrin, but had little, if any, effect on the persistence of Carbaryl. Results for d-fenothrin were inconclusive.
