Presentation by Lou Nelms.
In 2017 and 2018 the widespread application of dicamba herbicide on dicamba tolerant soybeans has brought much attention to off-target impacts of plant growth regulator herbicides to native plants. Due to the growing uses of dicamba and 2,4-D on corn and soybeans the public needs to become more aware of the far reaching threats posed by the volatile nature of these highly toxic, synthetic auxin herbicides. The presentation focuses on the visible leaf symptoms observed on oaks and other tree species the past two years.
