PRODUCT INFORMATION
F9387-1 herbicide contains two active ingredients possessing both contact and systemic activity that can be applied Post emergence for selective control of broadleaf weeds in field corn, seed corn, yellow pop-corn, sweet corn. Do not apply to White Popcorn or ornamental (Indian) corn. When applied as POST application it may take 2 to 15 days to kill the weeds on the list. The product is absorbed through the soil and /or by the weed foliage. For effective control of grasses, F9387-1 can be tank mixed with other POST grass herbicides to provide broader spectrum weed control in corn. F9387-1 application can also be combined with a burndown herbicide, prior to planting, to provide added burndown and residual weed control in field corn, seed corn, yellow popcorn, and sweet corn.

RESISTANCE MANAGEMENT 
F9387-1 contains both a group 14 and a group 27 herbicide. Some weeds are known to develop resistance to herbicides that have been used repeatedly. While the development of resistance is well understood, it is not easily predicted. Therefore herbicides should be used in  conjunction with resistance management strategies in the area. Consult the local or State agricultural advisors for details. If weed resistance should develop in the area, this product used alone may not continue to provide sufficient levels of weed control. If the reduced levels of control cannot be attributed to improper application timing, unfavorable weather conditions or abnormally high weed pressure, a resistant strain may have developed. To reduce the potential for weed resistance, use this product in a rotation program with other classes of chemistry and modes of action. Always apply this product at the recommended rates and in accordance with the use directions. For optimum performance, scout fields carefully and begin applications when weeds are smaller rather than larger.

DIRECTIONS FOR USE
Misuse Statement
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. FAILURE TO FOLLOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS LABEL MAY RESULT IN POOR WEED CONTROL, CROP INJURY, OR ILLEGAL RESIDUES.
Utilize a sprayer equipped with the appropriate nozzles providing optimum spray distribution and coverage at the appropriate operating pressures. Utilize nozzles that produce minimal amounts of fine spray droplets to avoid spray drift. Apply a minimum of 10 gallons of finished spray solution per acre by ground. If a dense crop and or weed canopy is present use a minimum of 15 gallons per acre of finished spray volume by ground application. For best results apply F9387-1 with medium spray droplets. The sprayer should be properly calibrated to deliver the appropriate volume of herbicide solution. Be aware that overlaps and slower ground speeds while starting, stopping or turning while spraying may result in excessive application and subsequent crop response. Mix the amount which will be used for spraying on that day.

Restrictions
x Do not exceed 3.15 fl oz. (0.098 lb. a.i./A of F9387-1 contains 0.0053 lb ai fluthiacet methyl + 0.0931 lb ai mesotrione) in a single postemergence application.

x Do not apply more than 0.0089 lb ai of fluthiacet-methyl or 0.24 lb of mesotrione per cropping season including all preplant or postemergence herbicides containing these active ingredients.

Use precautions
1. Avoid drift onto adjacent crops.
2. Severe corn injury may occur if F9387-1 is applied postemergence to corn that was treated with Counter or Lorsban in-furrow at planting, which may result in corn crop yield loss.
3. Severe corn injury may occur if F9387-1 is applied foliar postemergence in a tank mix with any organophosphate or carbamate insecticide which may result in corn crop yield loss.
4. Severe corn injury may occur if any organophosphate or carbamate insecticide is applied foliar postemergence within 7 days before or 7 days after F9387-1 application, which may result in corn crop yield loss.
5. Do not cultivate corn within 7 days before or after a F9387-1 application as weed control from the F9387-1 application may be reduced.
