摘要

(S)-Alpha-cyano-3-phenoxy-benzyl 1R, cis 2,2-dimethyl-3-(2,2- dichlorovinyl) cyclopropane-1-carboxylate (cpd.A) is used to control parasitic acarien. Cpd. A is known and may be prepd. by the method of FR 2375161. Its use against plant acarien and nematodes is described in FR2402411. The compsns. may be applied externally or admin. parenterally, orally or ractally. Typical emulsifiable solns. for external admin. contain 3-10 wt.% of Cpd. A. Synergistics for pyrethrinoids, e.g. piperonyl butoxide, may be added in amts. of 2-20 wt. parts, esp. 5-12 wt. parts, per part of Cpd. A. Acaricide and acarifuge used to control ixodidae and sarcoptidae e.g. ticks, such as Boophilus, Hyalomma, Ambylomma and Phipicephalus and mite such as sarcoptic, psoroptic and chorioptic types. The compsns. are used to treat cattle, sheep, pigs, poultry, dogs, cats etc. Cpd. A is very well tolerated e.g. s.c. admin. and has excellent activity.
