Abstract
Acaricidal aryl arylthien-2-yl ethenes of the formula ##STR1## in which R.sup.2 and R.sup.3 are each an optionally substituted phenyl or thienyl group are disclosed and claimed.
Claims6
An acaricidal compound of the formula ##STR3## in which R and R.sup.1 are independently selected from hydrogen, halogen, lower alkyl, lower aloxycarbonyl, and N(CO.sub.2 C.sub.2 H.sub.5)(CH.sub.2 C.sub.6 H.sub.11);
- and R.sup.2 and R.sup.3 are each independently selected from the group consisting of phenyl which may be substituted with halogen, lower alkyl, lower alkoxy, trifluoromethyl, or dimethylpyrrolyl and thienyl which may be substituted with lower alkyl or trimethyl silyl, with the proviso that at least one of R.sup.2 and R.sup.3 is other than phenyl or alkylphenyl.
An acaricidal composition comprising an acaricidal amount of a compound of the formula ##STR4## in which R and R.sup.1 are independently selected from hydrogen, halogen, lower alkyl, lower alkoxycarbonyl, and N(CO.sub.2 C.sub.2 H.sub.5)(CH.sub.2 C.sub.6 H.sub.11) and R.sup.2 and R.sup.3 are each independently selected from the group consisting of phenyl which may be substituted with halogen, lower alkyl, lower alkoxy, trifluoromethyl, or dimethylpyrrolyl and thienyl which may be substituted with lower alkyl or trimethyl silyl in admixture with an agriculturally acceptable carrier, diluent, or adjuvant, with the proviso that at least one of R.sup.2 and R.sup.3 is other than phenyl or alkylphenyl.
A method for controlling acarids which comprises applying to a locus where control is desired an acaricidally effective amount of the compound of the formula ##STR5## in which R and R.sup.1 are independently selected from hydrogen, halogen, lower alkyl, lower alkoxycarbonyl, and N(CO.sub.2 C.sub.2 H.sub.5)(CH.sub.2 C.sub.6 H.sub.11) and R.sup.2 and R.sup.3 are each independently selected from the group consisting of phenyl which may be substituted with halogen, lower alkyl, lower alkoxy, haloalkyl, or dimethylpyrrolyl and thienyl which may be substituted with lower alkyl or trimethyl silyl.
