Summary The potential of the fungicide tridemorph selectively to control established plants of Holcus lanatus L. in ryegrass ( Lolium perenne L) and Bromus sterilis L. in barley ( Hordeum vulgare L.) was examined in glasshouse trails. A dose of 4.2 kg ha −1 tridemorph gave selectively between H. lanatus and ryegrass similar to, but more costly than, that which would be provided by 1.2 kg ha −1 asulam. B sterilis was more sensitive to tridemorph than was barley. Two additives, glycerol and the oil‐surfactant mixture ‘PF’ enhanced this selectivity when tridemorph was applied at 2.1 kg ha −1 .
