Grow Native! Old Herbicides Causing New Problems ASLA LACES

Dicamba and 2,4-D have traditionally been used on cropland during the early part of the growing season, when trees and other sensitive plants are still dormant.

With the release of crop varieties tolerant of these herbicides, however, summer applications are resulting in tree and native plant injury on a landscape level. This webinar will discuss the history of this issue and illustrate herbicide injury on trees. This is a webinar that was recorded live on October 11, 2023.

Your course materials (recording link, quiz link, and supplemental materials if applicable) will be delivered to you via email within 3 business days of successfully submitting registration. If you do not receive your materials within 3 business days, please contact Erika Van Vranken at
