Both non-native and native plants can spread into areas where they are not desired.
Videos: Year-round steps to identify and manage buckthorn
Research indicates buckthorn provides a winter host for soybean aphid. Buckthorn serves a shelter for soybean aphid eggs to overwinter. In addition, buckthorn also disrupts the balance of our natural world, pushing out desirable native understory plants and creating a dark, dense thicket.
In the first of the two videos below, Angela Gupta, University of Minnesota Extension forestry educator, shows how to identify buckthorn. The second video features farmers Michael Lynch (Watonwan County) and Rochelle Krusemark (Martin County), sharing their thoughts and practices about protecting both their crops and the environment.
These Extension videos were produced with support from Minnesota Soybean Research and Promotion Council.
