Aq. pyrethrinoid compsns. for use in aerosols as insecticides and parasiticides

摘要

Aq. insecticidal and parasiticidal compsns. comprise at least two pyrethrinoids resulting from the combination of tetramethrin and at least one phenoxybenzyloxycarbonyl deriv., and at least one ethylene oxide surfactant. The compsn. may also comprise a fatty acid ester and polyglycol surfactant, as well as a pyrethrinoid synergist such as piperonyl butoxide in an amt. of 0.50-3.00%. The phenoxybenzyloxycarbonyl deriv. is pref. permethrin or cypermethrin.
