STEADFAST herbicide is a water-dispersible granule used at the rate of 3/4 ounce per acre for selective postemergence grass and broadleaf weed control in field
corn. Do not apply to field corn grown for seed, to popcorn or to sweet corn. Do not make more than one application of STEADFAST per cropping season. Do not apply aerially in California or New York State.
WHEN TO APPLY
TIMING TO CROP STAGE
Apply STEADFAST to field corn hybrids with a relative maturity (RM) rating of 77 days or more, including "food grade" (yellow dent, hard endosperm), waxy and oil corn. Not all field corn hybrids of less than 77 days RM, not all white corn hybrids nor Hi-Lysine hybrids have been tested for crop safety, nor does DuPont have access to all seed company data. Consequently, injury arising from the use of STEADFAST on these types of corn is the responsibility of the user. Consult with your seed supplier before applying STEADFAST to any of these corn types. Applications of STEADFAST to corn hybrids of 77-88 CRM should be limited to corn that is 12” tall, less than or equal to 5-leaf collars, whichever is most restrictive. In addition, the application of tank mixtures with dicamba-containing herbicides (such as “Clarity” or “Distinct”) to 77-88 CRM corn should contain no more than 2 ounces a.i. dicamba (e.g. 4 ounces “Clarity”). Seed company publications indicate “Warning”, “Crop Response Warning”, or “Sensitive” notations for the use of some ALS herbicides on corn hybrids of 77 CRM or higher. As noted in the seed company publications, DuPont sulfonylurea herbicides such as STEADFAST should be used with caution on these hybrids. Consult with your local DuPont representative or the DuPont Label Web Site (http://cropprotection.dupont.com/) for any additional supplemental labeling information relative to potential corn hybrid sensitivity to STEADFAST. Limit STEADFAST applications to corn that is up to 12” tall, up to and including 5 leaf collars, whichever is most restrictive, in the states of KS, OK and TX.
