Summary Residues and side-effects of herbicids in forest protection1. The herbicids licensed by Biol. Bundesanst. f, Land- u. Forstwirtschaft Braunschweig (BBA) don't cause damages to flora and fauna of soil, to the quality of water and as soon as known to soundness of game.2. Damages to plants, to organisms living in water and to bees are avoidable by observing the directions.3. There is no fear that walkers or persons collecting berries and mushrooms would be exposed to danger by contacts with residues of herbicids. In particular danger boards should be set up.4. Injuries to health by eating berries, mushrooms or game treated with forest herbicids are not to be expected as far as the directions for treating has been observed. But in security for going beyond the tolerable limit of residues the treatment of berries with herbicids should be avoided. At present the decree of tolerable limits (Hö chstmengen-Verordnung) in plant protection is incomplete. The gaps should be filled under assimilation to tolerable limits of other countries.
