The invention relates to novel 2-aryliminohexahydropyrimidines and imidazolidines, of the formula ##STR1## as well as to salts and complexes thereof, having fungicidal activity. These compounds are particularly active against rust of beans, brown rust of wheat and mildew on cereals. After having been processed into compositions, the compounds of the invention can successfully be used to prevent or control mould infections in agriculture and horticulture in a dosage of 200-1000 g of active substance per hectare. Very active fungicides are, for example, 2-(4-cyclohexyl-phenyl) iminohexahydropyrimidine and 2-(4-n-hexyl-phenyl) iminohexahydropyrimidine, as well as the sulphuric acid salts of these compounds and complexes with zinc salts.
