1) The newer formulations of dicamba (Stryax\u00ae, Engenia\u00ae) are NOT<\/u><\/em><\/strong> labeled for this particular use.<\/p>\n\n\n\n 2) Older formulations of dicamba (Clarity\u00ae, Rifle\u00ae, Sterling Blue\u00ae) are labeled for this use depending upon tillage system and soil type as follows:<\/p>\n\n\n\n a) PREPLANT AND PREEMERGENCE APPLICATION IN NO TILLAGE CORN:<\/u><\/strong> Rates: Apply 16 fluid ounces of Clarity\u00ae, or Rifle\u00ae, or Sterling Blue\u00ae per acre on medium-or fine-textured soils containing 2.5% or greater organic matter. Use 8 fluid ounces per acre on coarse soils (sand, loamy sand, and sandy loam) or medium-and fine-textured soils with less than 2.5% organic matter. <\/p>\n\n\n\n b) PREEMERGENCE APPLICATION IN CONVENTIONAL OR REDUCED TILLAGE CORN:<\/u><\/strong> Rates: Apply 16 fluid ounces of Clarity\u00ae, or Rifle\u00ae or Sterling Blue\u00ae per treated acre to medium- or fine-textured soils that contain 2.5% organic matter or more. DO NOT<\/u><\/em><\/strong> apply to coarse-textured soils (sand, loamy sand, or sandy loam) or any soil with less than 2.5% organic matter until after corn emergence. <\/p>\n\n\n\n c) Failure to follow these recommendations could result in excessive crop injury. If a grower applies dicamba as a burndown in a field intended to be planted to dicamba-tolerant cotton or soybean and changes their mind and wants to plant field corn, please contact me ASAP. <\/p>\n\n\n\n 3) Everyone always asks me what my preferred burndown is for field corn. Lots of good choices. But, I prefer Roundup or Gramoxone + atrazine because these combos will control most of our common winter weeds and field corn can be planted immediately without concern for crop injury. See below.<\/p>\n\n\n\n I had a question or two about using dicamba for preplant burndown in corn. Dr. Prostko has a few comments on this subject below. It has come to my attention that the recommendations for preplant\/burndown applications of dicamba for field corn in the UGA Pest Control Handbook are NOT sufficiently described.
