It has strong contact and stomach poisoning activity, good residual activity and a mild knock down against fly, mosquito, roach and other pests in public, industrial area and household. It has spectacular expelling action to big roach such as periplaneta fuliginosa and periplaneta Americana. It is better than permethrin, fenpropathrin, prallethrin and d-phenothrin in prevention of wool and furpests such as grain moth and achievies best in mosquito-repellent test by dipping mosquito net in liquids of d-cyphenothrin, permethrin, d-phenothrin, fenpropathrin and fenvalerate respectively. APPLICATIONS Aerosols: The recommended dosages for use in aerosol are between 0.2% and 0.7%. EC: 3% to 5% content can be formulated with propoxur, to control cockroach.
