Mueller reports on his field and greenhouse (lab) studies detailing various aspects of dicamba behavior post-application (not related to particle drift). Specific topics include effects of plant material presence, comparison of dicamba formulations, temperature effects, spray mixture pH effects, and other general observations from multiple sources. Mueller has been conducting dicamba volatility research under field and lab conditions since 2009. The purpose of this presentation is to provide Mississippi farmers with ideas related to the best possible stewardship of post-dicamba products.
