Novel N-(3,5-dihalophenyl)imide compounds, which exhibit a strong antimicrobial activity against microorganisms including phytopathogenic fungi, parasites of industrial products and pathogenic microorganisms, represented by the formula, ##STR1## wherein X and X' each represent halogens and A represents a substituted ethylene such as chloroethylene, C.sub.1 - C.sub.4 alkylthioethylene, C.sub.1 - C.sub.2 alkyl-ethylene or 1,2-di-C.sub.1 - C.sub.2 -alkyl-ethylene, a cyclopropylene such as 1,3-dimethylcyclopropylene, trimethylene, a cyclohexylene-1,2-, cyclohexenylene-1,2-, cyclohexadienylene-1,2- or o-phenylene. The N-(3,5-dihalophenyl)imide compounds can be obtained by any of methods which produce imide compounds or reaction of an N-(3,5-dihalophenyl)maleimide compound with a mercaptan, a hydrogen halide, phosphorus chloride or thionylchloride.

Antimicrobial composition and method containing

Compounds of the formula ##EQU1## wherein R is phenyl, .alpha.-naphthyl, substituted phenyl or a group of the formula ##EQU2## R.sub.1 is lower alkyl, R.sub.2 is alkyl, phenyl, aralkyl or substituted phenyl, and R.sub.3 and R.sub.4 are lower alkyl, which compounds are useful as insecticidal, nematocidal and acarididal agents.
