• Outlook (dimethenamid-P) controls annual grasses and pigweed, and control or suppress yellow nutsedge and black nightshade.
• Mode of action: shoot meristem inhibitor.
• Can be applied up to 30 days before planting as a single application. When applying 30 to 45 days before planting, apply 2/3 of the full rate early, followed by 1/3 of the full rate after planting. Early preplant applications are not recommended for use on coarse-textured soils or where average annual rainfall exceeds 40 inches.
• Can be applied after planting and crop emergence, but must be applied before weed emergence, or in a tank mixture with herbicides that control emerged weeds. Do not apply to corn that is more than 12 inches tall.
• May be applied after corn has emerged with surfactant or low rates of liquid nitrogen fertilizer. Do not use liquid fertilizer as the spray carrier after the crop has emerged. Crop oil concentrate should not be added after the crop has emerged unless specified for a particular tank mixture.
