As a landowner, manager, or service provider, you may understand the need to use herbicides to control invasive species and reach other woodland management goals. However, you may be unsure of which herbicides to use in different situations, how to use equipment properly, as well as other questions. This workshop will provide experts to address your questions and concerns using inside and field demonstration.  Several herbicide treatments were applied to a test area in late August so you can see the impact of different treatments in the field.
