Features & Benefits
- Product Information
MESOTRYONE 4L is a systemic pre-emergence and post-emergence herbicide for the selective contact and residual control of broadleaf weeds in Field corn, Seed corn, Sweet corn, Yellow popcorn and other listed crops. When used pre-emergence, weeds take up the product through the soil during emergence. Dry conditions following application may reduce the pre-emergence activity of this product. If an activating rain (0.25 inches) is not received within 7 to 10 days after a pre-emergence application, where appropriate, rotary hoeing is suggested to activate the herbicide. When used post-emergence, susceptible weeds take up the herbicide through the treated foliage and cease growth soon after application. Complete death of the weeds may take up to 2 weeks. The product is absorbed through the soil and / or by the foliage of emerged weeds.This product is not effective for the control of most grass weeds. Pre-emergence grass herbicides or post-emergence grass herbicides can be tank-mixed with this product to provide broad spectrum weed control in Corn (see appropriate section of label for this information). This product can be applied post-emergence following a pre-emergence grass herbicide application. This product can also be used in combination with a burndown herbicide prior to planting to provide added burndown and residual weed control in Field corn, Seed corn, Sweet corn and Yellow popcorn.

- Direction For Use
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.
- Agricultural Use Requirements
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR Part 170. This standard con-tains requirements for the protection of agricultural workers on farms, forests, nurseries, greenhouses and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label about Personal Protective Equipment (PPE) and Restricted Entry Interval (REI). The requirements in this box only apply to uses of this product that are covered by the Worker Protection Standard.
Do not enter or allow worker entry into treated areas during the restricted entry interval of 48 hours. For greenhouse uses, do not enter or allow worker entry into treated areas during the REI of 24 hours.
For at least seven days following the application of Copper-contain-ing products in greenhouses:
• at least one container or station designed specifically for flushing eyes is available in operating condition with the WPS-required decontamination supplies for workers entering the area treated with Copper-containing products,
• workers are informed orally, in a manner they can understand:
– that residues in the treated area may be highly irritating to their eyes,
– that they should take precautions, such as refraining from rub-bing their eyes, to keep the residues out of their eyes,
– that if they do get residues in their eyes, they should immedi-ately flush their eyes with the eye flush container that is located with the decontamination supplies and
– how to operate the eye flush container or eye flush station.
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with any-thing that has been treated, such as plants, soil or water is: Coveralls, chemical-resistant gloves made of any waterproof material, shoes plus socks and protective eyewear.
- Non-Agricultural Use Requirements
The requirements in this box apply to uses of this product that are not within the scope of the WPS for agricultural pesticides, 40 CFR part 170. The WPS applies when this product is used to produce agricultural plants on farms, forests, nurseries or greenhouses. Do not enter treated area until spray has dried.
- Use Precautions
Post-emergence applications of this product in tank-mixes with emulsifiable concentrate grass herbicides may cause severe Corn injury or yield loss under adverse weather conditions.
• Severe Corn injury resulting in yield loss may occur if this product is applied post-emergence to Corn that was treated with Terbufos (e.g., Counter®) or Chlorpyrifos (e.g., Lorsban®).
• Severe Corn injury resulting in yield loss may occur if this product 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 application of this product.• 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 this product is made following label directions when weeds are actively growing.
• This product may be applied with pyrethroid type insecticides (e.g., Lambda-cyhalothrin).

Safety & Health
- Precautionary Statements
Hazards to Humans and Domestic AnimalsCAUTION: Harmful if swallowed or absorbed through skin. Causes moderate eye irritation. Avoid contact with eyes, skin or clothing. PERSONAL PROTECTIVE EQUIPMENT (PPE)Applicators and other handlers must wear: Long-sleeved shirt and long pants, chemical-resistant gloves (such as nitrile, butyl, neoprene and/or barrier laminate), shoes plus socks.Follow manufacturer’s instructions for cleaning/maintaining PPE. If no such instructions for washables exist, use detergent and hot water. Keep and wash PPE separately from other laundry.
Engineering Controls When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for agricultural pesticide [40 CFR 170.240(d)(4-6)], the handler PPE requirements may be reduced or modified as specified in the WPS.
- Environmental Hazards
Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the mean high water mark. Do not contaminate water when disposing of equipment washwater or rinsate.
Surface Water Advisory
This product may contaminate water through drift of spray in wind. This product has a high potential for runoff for several weeks after application. Poorly draining soils and soils with shallow water tables are more prone to produce runoff that contains this product. A level, well maintained vegetative buffer strip between areas to which this product is applied and surface water features such as ponds, streams and springs will reduce the potential for contamination of water from runoff. Runoff of this product will be reduced by avoiding applications when rainfall is forecasted to occur within 48 hours. Sound erosion control practices will reduce this product’s contribution to surface water contamination.
PHYSICAL AND CHEMICAL HAZARDS
Do not use or store near heat or open flame.
