Verify® ATZ is recommended for control of yellow nutsedge and many annual grasses and broadleaf weeds listed in the “WEEDS CONTROLLED” section of the product label. This product alone will not control emerged seedlings.

Verify ATZ may be applied either as a surface application before or after planting, or after crop emergence. It may also be shallowly incorporated prior to planting to blend the herbicide treatment into the upper 1 to 2 inches of soil. Except for minimum or conservation tillage systems, the seedbed should be fine, firm and free of clods and trash.
