PCT No. PCT/JP95/00852 Sec. 371 Date Dec. 28, 1995 Sec. 102(e) Date Dec. 28, 1995 PCT Filed Apr. 28, 1995 PCT Pub. No. WO95/29591 PCT Pub. Date Nov. 9, 1995The present invention provides a preventive agent for fouling organisms, which comprises, as an effective ingredient, at least one compound selected from compounds represented by general formula (1) <IMAGE> (1) [wherein R1 is a lower alkyl group, or a phenyl group which may be substituted with a halogen atom(s) and/or a lower alkyl group(s); each X1 is a halogen atom; n is an integer of 1-5; when n is 2 or more, X1s may be the same or different; and Y1 is a hydrogen atom or a group -Z-Y2 (Z is a carbonyl group or a sulfonyl group, and Y2 is a substituted or unsubstituted aryl group or a lower alkyl group], or salts thereof. The present preventive agent for fouling organisms, which contains a compound(s) other than organotin compounds as an effective ingredient, has high safety, prevents the settlement of fouling organisms to ships, in-water structures, fishing nets, etc. at a low effective ingredient content, and exhibits an antifouling effect stably over a long period of time.
