Mesotrione 4SC is a systemic pre-emergence and post-emergence herbicide for selective contact and residual control of broadleaf weeds in field corn, seed corn, yellow popcorn, sweet corn, and other listed crops. When used pre-emergence, weeds take up the product through the roots and shoots by means of systemic translocation. When used post-emergence, susceptible weeds take up the herbicide through the treated foliage and cease growth soon after application.

Features & Benefits

Product Features
  • Mesotrione 4SC offers excellent application flexibility, crop safety and proven performance in the residual control of a variety of broadleaf weeds.
  • Mesotrione 4SC can be tank mixed with all Gly Star® branded glyphosate products to provide exceptional grass and broadleaf control in pre-emergence and/or post-emergence herbicide applications.
  • In combination with atrazine, Mesotrione 4SC provides excellent control of tough weeds such as waterhemp, lambsquarters, ragweed and pigweed.

  CORN

  • Mesotrione 4SC offers control of broadleaf weeds until crop canopy and excellent crop safety in corn when applied according to the label.
  • Mesotrione 4SC provides the grower with flexibility to apply pre-emergent and/or post-emergent to obtain excellent broadleaf weed control.
  • Mesotrione 4SC is readily absorbed by roots, leaves and shoots resulting in rapid distribution throughout the target weed.
  • In combination with other corn grass herbicides, Mesotrione 4SC provides an alternative to glyphosate alone to improve resistant weed management.

Applications & Uses

Application Information

PRE-EMERGENCE GROUND APPLICATION

Apply Mesotrione 4SC pre-emergence with a carrier volume of 10-60 gals/A.

Spray nozzles must be uniformly spaced, the same size and type, and must provide accurate and uniform application. Use spray nozzles that provide medium to coarse droplet size to provide good coverage and avoid drift. Apply in a spray volume of 10–60 gals/A using water or liquid fertilizer (excluding suspension fertilizers) as the carrier. Use a pump that can maintain a pressure of at least 35-40 psi at the nozzles and provide proper agitation within the tank to keep the product dispersed. Lower pressures may be used with extended range or drift reduction nozzles.

Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time. If the agitation is stopped for more than 5 minutes, resuspend the spray solution by running on full agitation prior to spraying.

POST-EMERGENCE GROUND APPLICATION

Spray nozzles must be uniformly spaced, the same size and type, and must provide accurate and uniform application. Use spray nozzles that provide medium to coarse droplet size to provide good coverage and avoid drift. Good weed coverage is essential for optimum weed control. Boom height for broadcast over-the-top applications must be based on the height of the crop—at least 15 inches above the crop canopy.

Apply in a spray volume of 10-30 gals/A using water as a carrier. Add an appropriate adjuvant to the spray tank when applying post-emergence (see label). Use a pump that can maintain a pressure of at least 35-40 psi at the nozzles and provide proper agitation within the tank to keep the product dispersed. Lower pressures may be used with extended range or drift reduction nozzles. When weed foliage is dense, use a minimum of 20 gals.

Use Precautions

Severe corn injury resulting in yield loss may occur if Mesotrione 4SC is applied post-emergence to corn that was treated with Counter® or Lorsban®.

Severe corn injury resulting in yield loss may occur if Mesotrione 4SC is applied foliar post-emergence to corn in a tank mix with any organophosphate or carbamate insecticide.

Severe corn injury resulting in yield loss may occur if any organophosphate or carbamate insecticide is applied foliar post-emergence within 7 days before or 7 days after Mesotrione 4SC application.

When weeds are stressed due to drought, heat, lack of fertility, flooding, or prolonged cool temperatures, control can be reduced or delayed since the weeds are not actively growing. Weed escapes or regrowth may occur when application is made under prolonged stress conditions. Optimum weed control will be obtained if an application of Mesotrione 4SC is made following label directions when weeds are actively growing.

Mesotrione 4SC may be applied with pyrethroid type insecticides (e.g., Warrior®).
