Summary Crataegus monogyna, Prunus spinosa, Fraxinus excelsior and Sambucus nigra, common woody species of hedgerows, were grown in pots and treated in June with half and full recommended rates of 15 herbicides and three plant growth regulators. C. monogyna was affected by fewest compounds, while the other three species showed differing tolerances. The wild‐oat herbicides, diclofop‐methyl, flamprop‐m‐isopropyl and difenzoquat did not adversely affect the shrubs. Plant growth regulators used at rates recommended for cereals and grassland had only minor effects. Clopyralid killed only S. nigra, while mecoprop, fluroxypyr, chlorsulfuron, metsulfuron‐methyl and glyphosate caused significant damage to most species. Height of C. monogyna was increased after treatment with diclofop‐methyl, difenzoquat, ethofumesate, mefluidide and chlormequat.
