Abstract
Abstract There is disclosed a fungicidal composition comprising (A) a fungicidal benzimidazole compound of the formula <IMAGE> wherein W is H, or alkyl carbamoyl; Y is H, halogen, alkyl, alkoxy, alkyl thio, thiol, carbamic acid ester or hydroxy; Z is H, halogen or alkyl; and (B) a synergist alkyl pyridinium salt of the formula <IMAGE> wherein R is an alkyl containing 8 to 20 carbon atoms; and X is a monovalent anion.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
109 words
A fungicidal composition with increased fungicidal activity, against benomyl tolerant fungi comprising (A) 0.1 to 90% by weight of methyl 1-(n-butylcarbamoyl)-2-benzimidazolecarbamate, and (B) 0.2 to 2 parts by weight of an alkyl pyridinium salt with the formula: ##STR6## wherein R represents an alkyl radical containing 12 to 16 carbon atoms and X is a monovalent anion, per part of the benzimidazole, wherein the composition is formulated such that when a further diluted aqueous solution containing 1 to 1,000 ppm of the benzimidazole insecticide is applied to fungi or habitats thereof, the concentration of the alkyl pyridinium salt in the diluted aqueous solution is below its critical micelle concentration level.
Claim 2
Dependent Claim
109 words
A fungicidal composition with increased fungicidal activity, against benomyl tolerant fungi comprising (A) 0.1 to 90% by weight of methyl 1-(n-butylcarbamoyl)-2-benzimidazolecarbamate, and (B) 0.2 to 2 parts by weight of an alkyl pyridinium salt with the formula: ##STR6## wherein R represents an alkyl radical containing 12 to 16 carbon atoms and X is a monovalent anion, per part of the benzimidazole, wherein the composition is formulated such that when a further diluted aqueous solution containing 1 to 1,000 ppm of the benzimidazole insecticide is applied to fungi or habitats thereof, the concentration of the alkyl pyridinium salt in the diluted aqueous solution is below its critical micelle concentration level.
Claim 3
Dependent Claim
26 words
A composition according to claim 1, wherein the alkyl pyridinium salt is dodecyl pyridinium chloride or bromide, tetradecyl pyridinium chloride or bromide, or a mixture thereof.
Claim 4
Dependent Claim
27 words
A composition according to claim 2, wherein the amount of the alkyl pyridinium chloride is 1/3 to 3 parts by weight per part of the benzimidazole compound.
Claim 5
Independent Claim
99 words
A method of combatting strains of Benomyl tolerant or resistant fungi, which comprises applying to fungi or habitats thereof an aqueous solution containing 1 to 1,000 ppm of methyl 1-(n-butylcarbamoyl)-2-benzimidazolecarbamate and an alkyl pyridinium salt of the formula: ##STR7## wherein R represents an alkyl radical containing 12 to 16 carbon atoms and X - is a monovalent anion, wherein the amount of the alkyl pyridinium salt is 0.2 to 2.0 parts by weight per part of the benzimidazole fungicide provided that the concentration of the alkyl pyridinium salt in the aqueous solution is below the critical micelle concentration level.
Claim 6
Independent Claim
99 words
A method of combatting strains of Benomyl tolerant or resistant fungi, which comprises applying to fungi or habitats thereof an aqueous solution containing 1 to 1,000 ppm of methyl 1-(n-butylcarbamoyl)-2-benzimidazolecarbamate and an alkyl pyridinium salt of the formula: ##STR7## wherein R represents an alkyl radical containing 12 to 16 carbon atoms and X - is a monovalent anion, wherein the amount of the alkyl pyridinium salt is 0.2 to 2.0 parts by weight per part of the benzimidazole fungicide provided that the concentration of the alkyl pyridinium salt in the aqueous solution is below the critical micelle concentration level.
Claim 7
Dependent Claim
15 words
A method according to claim 4, wherein the aqueous solution is applied to a plant.
Claim 8
Dependent Claim
17 words
A method according to claim 5, wherein the aqueous solution is applied to benzimidazole-tolerant or -resistant fungi.
Claim 9
Dependent Claim
26 words
A method according to claim 5, wherein the alkyl pyridinium salt is dodecyl pyridinium chloride or bromide, tetradecyl pyridinium chloride or bromide or a mixture thereof.
Claim 10
Dependent Claim
23 words
A method according to claim 7, wherein the aqueous solution is applied such that the benzimidazole fungicide is applied 0.1 to 10 kg/ha.
Claim 11
Dependent Claim
24 words
A method according to claim 7, wherein the aqueous solution is applied to Benomyl tolerant or resistant strains of Botrytis cinerea or Monilia fructicola.
