Abstract

This invasive plant management study focuses on the treatment of younger and older seedproducing black cherry (Prunus serotina Ehrh.) individuals. We injected the older trees and applied bark treatment to the thinner saplings in 2018. Over two vegetation periods, we studied the effect of 11 herbicides and ranked the treatments based on their introduced foliage loss and sprouting. In the trunk injection experiment, the most effective treatment was a combination of glyphosate and clopyralid (Medallon Premium-Lontrel 300). Compositions without glyphosate did not meet expectations. In the bark treatment experiment, the herbicides used were combinations of glyphosate and MCPA (Medallon Premium Mecomorn-750 SL), glyphosate and dicamba (Medallon Premium-Banvel 480 S), and glyphosate and clopyralid (Medallon Premium-Lontrel 300). Results indicate that all three treatments are effective. Some of the technologies and chemical combinations this study presents are recommendable considering current plant protection legislation.
