Enloe, and published by the UF Agronomy Department, December 2016.
After many years in development, dicamba will likely be fully approved for use in tolerant cotton varieties for the 2017 growing season. There is great concern that dicamba drift can result in significant losses in nearby sensitive crops. This concern is well-founded because many crops (such as soybean, snap bean, and peanut) are highly sensitive to extremely low doses of dicamba. All precautions must be followed if these new dicamba formulations are to be used. This 3-page fact sheet discusses herbicide selection, discontinued use of ammonium sulfate, nozzle selection, boom height, and wind speed. It also addresses a few frequently asked questions. Written by J. Ferrell and R. Leon, and published by the UF Agronomy Department, February 2017.
