DISEASE INJURY-CONTROLLING AGENT FOR CULTURED LAVER AND CONTROL OF DISEASE INJURY OF CULTURED LAVER

摘要

PURPOSE: To obtain a disease injury-controlling agent capable of controlling attached germs such as Olpidiopsis or Pyshium propagating during laver culture by the germicidal potency of the contained acid itself without damaging laver and also without causing marine environmental pollution, by mixing an aqueous formic acid solution with specific acid(s) such as phytic acid. ;CONSTITUTION: This disease injury-controlling agent is obtained by mixing a 0.3w/v% aqueous formic acid solution (part or the whole of the dispersion medium may be seawater) with an aqueous solution of at least one kind of acid selected from phytic acid, lactic acid, acetic acid, adipic acid, succinic acid, malic acid, citric acid, maleic acid, fumaric acid, gluconic acid, tartaric acid, monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, itaconic acid, glutaric acid, ketoglutaric acid, phosphoric acid, hydrochloric acid, sulfuric acid and nitric acid. In this case, the respective concentrations of these acids (except the formic acid) are set at 0.01-3w/v% correspondingly to the time necessary for treating object laver. Object cultured laver is immersed in the resultant mixed solution.;COPYRIGHT: (C)1996,JPO
