Oily dispersions having an improved systemic fungicidal activity are composed of about 5 to 30% by weight of BCM, about 60 to 85% by weight of an aliphatic mineral oil having a flash point of from 65.degree. to 180.degree. C and a viscosity of from 1.5 to 30 centipoise at 20.degree. C, about 6 to 15% by weight of a combination of dispersible agents comprising a monoalkylphenol polyglycol ether having from 8 to 12 carbon atoms and a triisobutylphenol polyglycol ether and about 0.1 to 3% by weight of calcium (C.sub.8 - C.sub.15) monoalkylbenzene sulfonate.

Fungicidal dispersions of a systemic fungicide

Stable dispersions having an improved systemic fungicidal activity are composed of about 5 to 30% by weight of 2-benzimidazole-methyl-carbamate, about 60 to 85% by weight of liquid esters of (C.sub.1 - C.sub.12) monoalcohols and (C.sub.2 - C.sub.10) carboxylic acids, about 2 to 10% by weight of a combination of a (C.sub.8 - C.sub.12)-monoalkylphenol polyglycol ether and castor oil polyglycol ether and about 0.1 to 5% by weight of Ca-(C.sub.8 -C.sub.15)-monoalkyl-benzene sulfonate.

Fungicidal dispersions of 2-benzimidazole-methyl-carbamate

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

Salts of benzimidazole-carbamic acid esters with certain organic sulfonic and sulfuric acid esters are substantially insoluble in water and soluble in organic solvents. These are valuable fungicides especially suitable for ultra low volume formulations.

Salts of alkyl 2-benzimidazole-carbamate

Fungicidal dispersions comprising a carboxylic acid amide, other than pyracarbolide, as the fungicidally-active ingredient and an aluminum chelate of a polynuclear hydroxy-quinone as a crystal growth stabilizer, dispersed in a paraffinic mineral oil, a liquid triglyceride, or a liquid ester formed between a C.sub.1 -C.sub.12 monoalcohol and a C.sub.2 -C.sub.10 mono- or di-carboxylic acid.

Fungicidal dispersions of carboxylic acid amides

The present invention relates to triazinobenzimidazoles and to a process for their preparation. The compounds are chemotherapeutics and are suitable for combating parasitary diseases in humans and animals; they are especially active against nematodes.

Substituted triazino-benzimidazoles

Dispersions of 2-methyl-5,6-dihydropyran-3-carboxylic acid anilide in paraffinic mineral oils, liquid triglycerides and/or liquid esters of C.sub.1 to C.sub.12 monoalcohols have an improved effect against rust diseases and an extended spectrum of effectiveness against diseases caused by Colletotrichum types. The dispersions can be stabilized against crystal growth by adding aluminum chelates of certain hydroxy quinones, e.g. allzarin.

Fungicidal dispersions of 2-methyl-5,6-dihydropyran-3-carboxylic acid

Triazino-benzimidazoles of the formula ##SPC1## In which R is a variety of substituents including alkyl, cycloalkyl, bi- and tricycloalkyl, phenyl and phenalkyl, are valuable fungicides.
