A thiazolidine compound represented by the following general formula I or its acid addition salt ##STR1## where X is --CH.dbd. or --N.dbd., Y is ##STR2## (where R is a hydrogen atom, a methyl group or an ethyl group) or --CH.sub.2 CH.sub.2 --, Ar is a phenyl group which may be substituted by halogen, lower alkyl, lower alkoxy, phenyl or trifluoromethyl, a thienyl group or a naphthyl group, R.sup.1 is a hydrogen atom, a straight chain or branched chain alkyl group having from 1 to 10 carbon atoms or a phenyl group which may be substituted, R.sup.2 is a hydrogen atom, a straight chain or branched chain alkyl group having from 1 to 10 carbon atoms, a phenyl group which may be substituted, a lower alkoxycarbonyl group, a lower alkylcarbamoyl group or a lower alkenylcarbamoyl group, and R.sup.3 is a hydrogen atom, a lower alkyl group, a lower acyl group, a lower alkylcarbamoyl group, a lower alkylthiocarbamoyl group or a phenylcarbamoyl group. The compound is useful as fungicide.

Thiazolidine compound and fungicidal composition containing it

Chemicals containing an effective amount of homopolymers of dialkylaminoalkyl acrylate derivatives or dialkylaminoalkyl methacrylate derivatives or copolymers of such derivatives with ethylenically unsaturated monomers copolymerizable therewith. The chemicals exhibit a remarkable effect of preventing agricultural plants from being infected with plant virus diseases. A method for controlling the plant virus diseases is also described.
