Abstract
Novel acaricide compositions containing as the active ingredient, a synergistic mixture of (S).alpha.-cyano-3-phenoxy-benzyl 1R, cis 2,2-dimethyl-3-(2',2'-dibromovinyl)-cyclopropane-1-carboxylate and either 2,2,2-trichloro-1,1-di-(4-chlorophenyl)-ethanol or a mixed anhydride of benzoic acid and 3-chloro-2,6-dimethoxy-N-ethoxy-benzenecarboximidic acid and to a novel method of combatting acariens.
Claims4
An acaricidal composition comprised of an acaricidally effective amount of a synergistic mixture of 1.5 to 50 parts by weight of (S).alpha.-cyano-3-phenoxy-benzyl 1R, cis 2,2-dimethyl-3-(2,2'-dibromovinyl)-cyclopropane-1-carboxylate and 100 parts by weight of a mixed anhydride of benzoic acid and 3-chloro-2,6-dimethoxy-N-ethoxy-benzenecarboxyimidic acid and an inert carrier.
A method of combatting acariens comprising contacting the acariens with an acaricidally effective amount of a composition comprised of a synergistic mixture of 1.5 to 50 parts by weight of (S).alpha.-cyano-3-phenoxy-benzyl 1R, cis 2,2-dimethyl-3-(2',2'-dibromovinyl)-cyclopropane-1-carboxylate and 100 parts by weight of a mixed anhydride of benzoic acid and 3-chloro-2,6-dimethoxy-N-ethoxy-benzene-carboximidic acid.
The method of claim 3 wherein a composition of claim 10 is applied at a rate of 100 to 350 g per hectare.
