Abstract

Abstract 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 C1 to C12 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.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 169 words
A fungicidal dispersion comprising 5 to 50% by weight of 2-methyl-5,6-dihydropyran-3-carboxylic acid anilide in combination with either benzimidazole-2-carbamic acid methyl ester in a proportion from 1.5:1 to 1:1.5 or 1-n-butyl-carbamoyl-benzimidazole-2-carbamic acid methyl ester in proportions from 1.5:1 to 1:1.5 and a C 8 to C 25 paraffin boiling at a temperature above 140° C, liquid triglycerides or liquid esters of C 1 to C 12 monoalcohols with C 2 to C 10 carboxylic acids, the esters containing at least 8 carbon atoms and at most 12 carbon atoms in the event the ester is of a monobasic acid, and at most 32 carbon atoms in the event the ester is of a dibasic acid or mixtures of said liquid triglycerides with said liquid esters further comprising 0.2 to 5% by weight, based on the total weight percent of the dispersion, of an aluminum chelate of a polynuclear hydroxy-quinone as a stabilizer, said chelate being selected from the group consisting of an aluminum chelate of naphthazarin, quinizarin, chrysazim and alizarin.
Claim 2
Dependent Claim 169 words
A fungicidal dispersion comprising 5 to 50% by weight of 2-methyl-5,6-dihydropyran-3-carboxylic acid anilide in combination with either benzimidazole-2-carbamic acid methyl ester in a proportion from 1.5:1 to 1:1.5 or 1-n-butyl-carbamoyl-benzimidazole-2-carbamic acid methyl ester in proportions from 1.5:1 to 1:1.5 and a C 8 to C 25 paraffin boiling at a temperature above 140° C, liquid triglycerides or liquid esters of C 1 to C 12 monoalcohols with C 2 to C 10 carboxylic acids, the esters containing at least 8 carbon atoms and at most 12 carbon atoms in the event the ester is of a monobasic acid, and at most 32 carbon atoms in the event the ester is of a dibasic acid or mixtures of said liquid triglycerides with said liquid esters further comprising 0.2 to 5% by weight, based on the total weight percent of the dispersion, of an aluminum chelate of a polynuclear hydroxy-quinone as a stabilizer, said chelate being selected from the group consisting of an aluminum chelate of naphthazarin, quinizarin, chrysazim and alizarin.
Claim 3
Dependent Claim 15 words
The fungicidal dispersion as claimed in claim 1, wherein the paraffin boils above 260° C.
Claim 4
Dependent Claim 18 words
The fungicidal dispersion as claimed in claim 1, wherein the liquid ester is a diester of phthalic acid.
Claim 5
Dependent Claim 16 words
The fungicidal dispersion as claimed in claim 1, wherein the diester is phthalic acid diisooctyl ester.
Claim 6
Dependent Claim 21 words
The fungicidal dispersion as claimed in claim 1, wherein the aluminum chelate of a hydroxy-quinone is an aluminum chelate of alizarin.
Claim 7
Dependent Claim 32 words
The fungicidal dispersion as claimed in claim 1, wherein the chelate content is in the range of from 0.4 to 2% by weight based on the total weight percent of the dispersion.
Claim 8
Dependent Claim 29 words
The fungicidal dispersion as claimed in claim 1, wherein the aluminum chelate is incorporated in situ by the addition of said hydroxy-quinone and an aluminum precursor of said chelate.
Claim 9
Dependent Claim 39 words
The fungicidal dispersion as claimed in claim 1, containing up to 20% by weight of an emulsifier and up to 5% by weight of wetting agent or adhesive, the precentages being calculated on the weight percent on said dispersion.
