Last week the SW x SW Corner CISMA coordinated a Japanese Knotweed Symposium, and I wanted to share one of the handouts that we passed out to attendees on JK treatment methods and sprayer calibration. Huge thanks to all that shared their info (Katie Grzesiak, Leslie Kuhn and Ardie Roth) used to create the document, and special thanks to Leslie for a LOT of editing, input and  and developing the sprayer calibration methods. Feel free
