Abstract
Novel 28-methyl-brassinosteroid derivatives of the general formula I < IMAGE > (in which Z represents -CO-O- CH2- or -O-CO-CH2-, and the 3 symbols R2, R3 and R22 each represents H or acyl, at least 1 of these 3 symbols representing acyl, or R22 represents H or acyl and R2 and R3 together represent < IMAGE > X representing H, optionally chlorinated C1-C4-alkyl or C1-C3- alkoxy and Y representing H, optionally chlorinated C1-C4-alkyl, C1-C3-alkoxy or optionally substituted aryl) and their manufacture. The novel compounds have a plant growth-regulating action, being particularly suitable for influencing the vegetative and generative growth of leguminous plants, for example soya bean plants, and accordingly may be made up with suitable carriers and/or auxiliaries into plant growth- regulating preparations and may be used for treating seeds, living plants and areas of land.
