If saflufenacil is added to one of the premixes that doesnt contain saflufenacil, add 20-30 gallons of UAN (if corn has not emerged) and MSO for burndown of small grasses and broadleaves. Substitute alternative corn post herbicides that control grasses and broadleaves, if they dont include a residual group 15 herbicide, add one to the postemergence mixture. Sinate 2.57L (topramezone [Impact] + glufosinate [Liberty]; groups 10, 27; AMVAC) can be used postemergence in field corn and sweet corn varieties that have the LibertyLink trait and controls many annual grasses and broadleaf weeds. The second choice would be to use clethodim for grasses + other herbicides to control broadleaf weeds. Its burndown activity is best when applied to young (generally less than 5 in. If it is non-GMO or straight Roundup Ready or Liberty Link, remember that there will be a preplant interval for 2,4-D or dicamba. ProClova is not yet registered but is anticipated by 2022. For weeds that break through the residual treatment, use glufosinate + dicamba or glyphosate + dicamba and add a 1/3 to label rate of the atrazine premix product that contains a group 15 herbicide to lengthen the window of residual weed control in the crop.
Paraquat updates: Anyone handling and using products containing paraquat (i.e. A field is planted to multi specie mixture of cover crops that contains cereal rye, (and to a lesser extent annual rye) and other species which include legumes and brassicas.
