PROBLEM TO BE SOLVED: To provide a new 4-trifluoromethylindole-3-acetic acid having a plant growth regulation action, its ester derivative or metal salt and its use. SOLUTION: The method for preparing a 4-trifluoromethylindole-3-acetic acid represented by general formula 1 (wherein R is hydrogen, an alkyl group, an alkenyl group or a metal salt) or its derivative is provided. The plant growth agent comprises the compound as an active ingredient and has a strong promotion action on formation of plant root. Consequently, the new compound has strong promotion action on rooting, is synthesized in a large amount and exhibits strong auxin activity at low concentration. The new plant growth regulator comprises the compound as an active ingredient. COPYRIGHT: (C)2009,JPO&INPIT |
