Methods of combating Acer negundo L. in specially protected natural areas

Abstract

The possibility of using chemical and mechanical methods to control the undesirable growth of the invasive species Acer negundo L. at the expositions of the Main Botanical Garden of the Russian Academy of Sciences, which has the status of a specially protected natural area, was studied. It was found that treatment of freshly cut stumps of A. negundo with glyphosphate in concentration of 7.2 g/l causes death of 65% of plants. In the rest of the specimens of A. negundo from this option the amount of growing epicormic sprouts decreased by 5.2 times in comparison with the usual cutting (control).
