Patent ID: 7005451

Claim:
A disinfecting agent for combating and inactivating phytopathogenic organisms that are present on plants and on hard surfaces surrounding the plants, said agent comprising at least one anionic surfactant, at least one aliphatic carboxylic acid, at least one aromatic carboxylic acid, mono-, di- and/or triglycols, at least one hydrotropic agent and at least one primary and/or secondary aliphatic, monovalent alcohol having a chain length of C 2 to C 8 in aqueous solution, wherein said agent, when contacted with phytopathogenic organisms present on plants or on hard surfaces, kills or inactivates the phytopathogenic organisms without damaging the plants and without leaving phytotoxic residues on the hard surfaces, wherein the aliphatic and aromatic carboxylic acids are selected from the group consisting of methanoic acid, ethanoic acid, propanoic acid, hydroxyethanoic acid, 2-hydroxypropionic acid, oxoethanoic acid, 2-oxopropionic acid, 4-oxovaleric acid, benzoic acid, o-, m-, p-hydroxybenzoic acids, 3,4,5-tri-hydroxybenzoic acid, and mixtures thereof, and wherein the anionic surfactant has a primary chains of a length of C 8 –C 18 and is selected from the group consisting of alkyl sulfonates, alkylarylsulfonates, the sodium-, potassium- and ammonium salts of alkyl sulfonates and alkylarylsulfonates, wherein the mono-, di- and/or triglycols are selected from the group consisting of ethylene glycol, propylene glycol, 2,3-butylene glycol, diethylene glycol [2,2′-dihydroxydiethylether], triethylene glycol [(1,2-di-2-hydroxyethoxyl-ethane], and mixtures thereof, and wherein the hydrotropic agent is selected from the group consisting of toluene sulfonate and cumene sulfonate as sodium- or potassium salts.
