Product Overview

Focus herbicide provides extended control of a broad range of grassy and broadleaf weeds, helping create a weed-free period for your crop to thrive at a critical point in the growing season. The early-season weed control also gives you more flexibility to complete your in-crop applications in other crops.

Focus herbicide doesn’t bind to crop residues on the soil surface and can be tank-mixed with glyphosate for faster burnoff of emerged weeds. By combining modes of action from Groups 14 and 15, Focus herbicide gives growers an effective way to control weeds resistant to other modes of action, and also avoid the buildup of future weed resistance.

Apply Focus herbicide at either pre-seed or pre-emergence timing. Because it requires 15 to 25 mm of rain for activation, the product can be applied early in the season to maximize the chance of moisture activation. If you can’t be in the field to seed, or it’s too cool to spray glyphosate, that’s the time to get your Focus herbicide down.
