The incidence of glyphosate resistant weeds has increased in the Southeastern U.S. Glyphosate resistant Palmer amaranth has become a major problem for many Georgia farmers. Increased production of glyphosate resistant soybean in Georgia will only confound this major issue unless farmers use residual herbicides in their production systems. Metribuzin can be utilized to assist in weed control, including Palmer amaranth, and provide residual activity. However, the use of newer soybean cultivars that have not been screened for tolerance to metribuzin could lead to significant injury and even crop failures. How these cultivars respond to metribuzin should be evaluated in order to determine potential...
