Carbamoyl derivatives of alkanolamines have general formula (I), where R<1>=C1-C5-alkyl, phenyl, C2H5OCH2CH2, C3-C5-fluoroalkyl, containing from 2 to 6 atoms of fluorine; R=H, or (a), where R<2>=H, C1-C2-alkyl; R<3>=methyl, cyclohexyl, phenyl, chlorophenyl-sulphonyl, benzyl, naphthyl, C6H3R<4>, R<5>, where R<4>=R<5>=Cl or R<4>=H; R<5>=Cl, methyl, trifluoromethyl, a nitro or methoxy group; n=2 or 3; when R=H then R<1>=C2H5OCH2CH2 or C3-C5-fluoroalkyl containing from 2 to 6 atoms of fluorine; when R=(a), then R<1>=C1-C4-alkyl or phenyl. The claimed antistress-type means for plant growth regulation contains, as active component, the carbamoyl derivatives of alkanolamines of the above-mentioned formula. |
