Abstract
Addition of 1% (AI) Virol (a California-type, medium-range petroleum oil) to 0.005% (AI) fenpropathrin applied under high-volume spray conditions resulted in a higher mortality of Bemisia tabaci (Gennadius) adults than that obtained when the two materials were applied separately. The LD50 of fenpropathrin applied with 1% Virol (0.013 μg/cm2) was ca. 5-fold lower than when fenpropathrin was applied alone (0.062 μg/cm2). However, addition of Virol to fenpropathrin under low-volume spray conditions had no effect either on toxicity or on fenpropathrin residue. Thus, addition of petroleum oil to fenpropathrin may have important practical implications in controlling B. tabaci only when sprays are applied at high volume.This publication has 3 references indexed in Scilit:
