EXTERMINATION OF PARASITE AND AQUATIC MICROORGANISM PARASITIC ON MARINE ORGANISM AND CONTROLLING AGENT

摘要

PROBLEM TO BE SOLVED: To obtain an expellent for parasites or aquatic microorganisms which parasitize marine organisms, having low toxicity and exhibiting effect at a low concentration by including a (tetrahydro-3-furanyl)methylamine derivative. ;SOLUTION: This expellent comprises generally 0.001-100 wt.%, preferably 0.001-99 wt.%, more preferably 0.005-20 wt.% at least one kind of (tetrahydro-3- furanyl)methylamine derivative of the formula (X₁ to X₇ are each H or a 1-4C alkyl; R1 is H, a 1-5C alkyl or the like; R2 is H, amino, methyl or the like; Z is N-NO₂, CH-NO₂ or N-CN). The marine organisms which become hosts of parasite include fishes, Crustacea, shellfishes, etc., in all age groups and targeted parasites include parasites and aquatic microorganisms ranging from Protista to Metazoa, and Monogenea, Trematoda, tapeworms, nematodes, Acanthocephala, Crustacea, etc., are exemplified as the parasites.;COPYRIGHT: (C)1999,JPO
