A study was conducted in 2007 at the Dean Lee Research Station, near Alexandria, LA to evaluate weed response to co-application of glyphosate and various zinc products.  Weeds evaluated consisted of Palmer amaranth, barnyardgrass, browntop millet, and Johnsongrass.  Weeds were visually rated for percent control at 7, 14, and 28 days after treatment.  Data were subjected to ANOVA and treatment means separated using Tukey’s adjustment at the 0.05 level of significance.
