BIOCIDE COMPOSITION AND A METHOD FOR TREATING WATER Russian patent published in 2018 - IPC A01N25/30 A01N25/10 A01N33/12 

FIELD: agriculture.

SUBSTANCE: group of inventions refers to a biocide composition and a method of treating water with its use. Biocide composition contains a biocide in a micelle. This micelle contains a block copolymer, which is a poloxamer, a quaternary ammonium stabilizing compound and a non-oxidizing biocide. Non-oxidizing biocide is selected from glutaraldehyde, 2,2-dibromo-3-nitrilpropionamide (DBNPA), 2-bromo-2-nitropropane-1,3-diol, 5-chloro-2-methyl-4-isothiazolin-3-one (CMIT), 2-methyl-4-isothiazolin-3-one (MIT), mixtures of CMIT and MIT, 1,2-dibromo-2,4-dicyanobutane, bis(trichloromethyl)sulfone, 2-bromo-2-nitrostyrene, 4,5-dichloro-1,2-dithiol-3-one, 2-n-octyl-4-isothiazolin-3-one, 1,2-benzisothiazolin-3-one, ortho-phthalaldehyde, guanidines, biguanidines, pyrithions, carbamates, 3-iodopropynyl-N-butyl carbamate, phosphonium salts, such as tetrakis (hydroxymethyl) phosphonium sulfate (THF), 3,5-dimethyl-1,3,5-thiadiazinan-2-thione, 2-(thiocyanomethylthio) benzothiazole, methylene- (bis) thiocyanate (MBT) and combinations thereof. Method for controlling biofilms by eliminating and / or preventing the emergence of microorganisms in an aqueous medium comprises the provision of said biocide composition and its dosing into the aqueous medium.

EFFECT: invention provides effective destruction of biofilms, including at low dosages.
