Weed Control Guide for Ohio Field Crops

• Op-Till is a premix of dicamba plus dimethenamid-P (Outlook) for preplant application in corn. Do not apply after corn planting.
• Op-Till provides burndown of emerged broadleaf weeds and residual control of grasses. See Banvel and Outlook labels for more information.
• To avoid crop injury, make sure seed is completely covered with soil and plant at least 1 1/2 inches deep. Application on coarse-textured soils within 7 days of planting may result in crop injury.
• The addition of surfactant, fertilizer solution, or crop oil may improve control of emerged weeds.
• Mix with 2,4-D to improve control of legume sods.
