A field experiment was conducted to study the efficacy of the two biocides namely Vertimec^® 18EC and Challenger 36% Sc and the Super-mesrona 94%EC 9 (oil), Endo 50% EC and Acromice (40 %), as control agents for Tetranychus urticae Koch and the leaf miner, Liriomyza sp. on three cultivars of faba bean Vicia faba (L.), sunflower and maize and their predators during the season 2012-2013. Acromic and Vertimec 18 EC enhanced the highest reduction percentage (42.2 and 40.6%) of T. urticae on the sunflower cultivar, followed by Endo and Challenger 36% Sc after three days from treatment. On the other hand, Endo enhanced the highest reduction percentage of T. urticae on maize (62.5%); while Endo and Challenger gave the highest reduction percentage of the predators followed by Acromic and Verttimec.
