Manage this Invasive Species

This is part two of a three-part series on the harmful plants and animals invading our watershed. Read part one of this series: Hemlock Woolly Adelgid: Near, But Not Yet Here.

There’s a new way to fight buckthorn on your property and its active ingredient might surprise you.

Common buckthorn (Rhamnus cathartica) is a hardy invasive shrub that reduces native plant diversity and negatively affects local wildlife. Buckthorn is labour intensive and costly to remove, but a new product is making it both safer and easier to control this troublesome and destructive plant.

Lalcide Chondro is a low-risk, biological herbicide that uses naturally occurring fungi (Chondrostereum purpureum) as its active ingredient. It’s applied as a paste directly to a freshly cut stump, meaning it’s not airborne and there’s little threat of cross-contamination or harm to other plants. It takes a growing season for the fungus to colonize and kill the shrub, but it’s shown effectiveness and is an alternative option to chemical herbicides.
