Dispersions of 2-methyl-5,6-dihydropyran-3-carboxylic acid anilide and benzimidazole-2-carbamic acid methyl ester or 1-n-butylcarbamoyl-benzimidazole-2-carbamic acid methyl ester in paraffinic mineral oils, liquid triglycerides and/or liquid esters of C.sub.1 to C.sub.12 monoalcohols have a synergistic effect against rust and other fungus diseases. The dispersions are stabilized against crystal growth by adding aluminum chelates of certain hydroxy-quinones, e.g., alizarin.

Fungicidal dispersions

Pesticidal compositions containing as active ingredients 2-(O,O-diethyl-thionophosphoryl)-5-methyl-6-carbethoxy-pyrazolo-(1,5a)-pyr imidine in admixture with (a) 2-methoxycarbonylamino-benzimidazole or (b) 1-(N-butylcarbamoyl)-2-methoxycarbonyl-amino-benzimidazole or (c) 1,2-bis(3-ethoxycarbonyl-2-thioureido)-benzene or (d) 1,2-bis-(3-methoxycarbonyl-2-thioureido)-benzene or (e) 1-(3-methoxycarbonyl-2-thioureido)-2-aminobenzene have a synergistic effect against phytopathogenic fungi.
