Abstract:
Conclusion of the control experiment: <br/> -Spraying with Combo is the most efficient, low cost- and least manpower-requiring treatment. <br/> -On the other hand, the commonly used concentrations of this herbicide resulted in high mortality rates of all other components of the vegetation.<br/> -Half of the application rate of Combo in combination with cutting reduces the impact on other vegetation dramatically, but is still highly efficient with respect to bracken.<br/> -Black-foil & cutting, or cutting alone proved as the best method for bracken control if herbicides are not allowed and other vegetation should be preserved.
