Abstract
Satisfactory control of horn flies (Siphona irritans) under field conditions was obtained for 3-6 weeks by spraying cattle withe either 0.25% or 0.5% Bayer 21/199. Better results were obtained with 0.5% methoxychlor, but there were some indications that the methoxychlor-treated herd was subjected to less reinfestation pressure.This publication has 0 references indexed in Scilit:
