Abstract

Residual herbicides were applied over Quercus rotundifolia Lam. (oak) and e. suber L. (cork-tree), before and active growing of trees by spraying and irrigation. Diuron and norflurazone were very phytotoxic. Orizalin and oxyfluorfen were tolerated satisfactorily. The other herbicides (simazine, thiazopyr, linuron + pendimethalin, isoxaben, tribenuron and glyphosate + diflufenican) showed variable responses. The tolerance of the trees was better before shooting than after active growing.
