RESTRICTED USE PESTICIDE
DUE TO GROUND AND SURFACE WATER CONCERNS
For retail sale to and use only by Certified Applicators, or persons under their direct supervision, and only for those uses covered by the Certified Applicator's certification. This product is a restricted use herbicide due to ground and surface water concerns. Users must read and follow all precautionary statements and instructions for use in order to minimize potential for atrazine to reach ground and surface water

A preemergence herbicide for control of annual grass and broadleaf weeds in field corn, production seed corn, silage corn, sweet corn, popcorn, Miscanthus and other non-food perennial bioenergy crops.

PRODUCT INFORMATION
For use only on field corn, production seed corn, silage corn, sweet corn, popcorn, Miscanthus and other non-food perennial bioenergy crops. Corn in this label refers to field corn, production seed corn, silage corn, sweet corn and popcorn. DuPont BREAKFREE NXT ATZ may be applied to the surface or incorporated into the top 1-2 inch layer of soil. It may be used for control alone, or in tank mix combinations, for the weeds listed in the "Target Weeds" section of these use directions. BREAKFREE NXT ATZ controls weeds by interfering with normal germination and seedling development. BREAKFREE NXT ATZ does not control established or emerged weeds present at application.

Restrictions
• Not for Sale, Sale Into, Distribution and/or Use in Nassau and Suffolk Counties of New York State.
• This chemical demonstrates the properties and characteristics associated with chemicals detected in ground water. The use of this chemical in areas where soils are permeable, particularly where the ground water is shallow, may result in ground water contamination.
• Do not apply BREAKFREE NXT ATZ before pre-irrigation in irrigated areas.
• Do not allow BREAKFREE NXT ATZ to contaminate feed or food.
• Do not contaminate irrigation water used for crops other than corn or water used for domestic purposes.
• Do not use BREAKFREE NXT ATZ on any crop other than field corn, production seed corn, silage corn, sweet corn, popcorn, and Miscanthus or other non-food perennial bioenergy crops.
• On the following soil types, do not apply this product within 50 feet of any well where the depth to groundwater is 30 feet or less: sands with less than 3% organic matter; loamy sands with less than 2% organic matter; or sandy loams with less than 1% organic matter. See the figure for additional clarification.

This product must not be mixed or loaded within 50 ft. of intermittent streams and rivers, natural or impounded lakes and reservoirs. This product must not be applied by ground within 66 feet of the points where field surface water runoff enters perennial or intermittent streams and rivers or within 200 feet around natural or impounded lakes and reservoirs. If this product is applied to highly erodible land, the 66-foot buffer or setback from runoff entry points must be planted to crop, seeded with grass or other suitable crop.
• This product must not be mixed or loaded, or used within 50 feet of all wells, including abandoned wells, drainage wells, and sinks holes. Operations that involve mixing, loading, rinsing, or washing of this product into or from pesticide handling or application equipment or containers within 50 feet of any well are prohibited unless conducted on an impervious pad constructed to withstand the weight of the heaviest load that may be positioned on or moved across the pad. Such a pad shall be designed and maintained to contain any product spills or equipment leaks, container or equipment rinse or washwater, and rainwater that may fall on the pad. Surface water shall not be allowed to either flow over or from the pad, which means the pad must be self-contained. The pad shall be sloped to facilitate material removal. An unroofed pad shall be of sufficient capacity to contain at a minimum 110% of the capacity of the largest pesticide container or application equipment on the pad. A pad that is covered by a roof of sufficient size to completely exclude precipitation from contact with the pad shall have a minimum containment capacity of 100% of the capacity of the argest pesticide container or application equipment on the pad. Containment capacities as described above shall be maintained at all times. The above specified minimum containment capacities do not apply to vehicles when delivering pesticide shipments to the mixing/loading site. Additional State imposed requirements regarding well-head setbacks and operational area containment must be observed.
• Tile-Outletted Terraced Fields Containing Standpipes To ensure protection of surface water from runoff through standpipes with tile-outlets in terraced fields, one of the following restrictions must be used in applying this product to tile-outletted terraced fields containing standpipes:
1. Do not apply this product within 66 feet of standpipes in tile-outletted terraced fields.
2. Apply this product to the entire tile-outletted terraced field and immediately incorporate it to a depth of 2-3 inches in the entire tile-outletted terraced field.
3. Apply this product to the entire tile-outletted terraced field under a no-till practice only when high crop residue management practices are used. High crop residue management is described as a crop management practice where little or no crop residue is removed from the field during or after crop harvest.
• Do not apply DuPont BREAKFREE NXT ATZ postemergence to sweet corn.
• Chemigation: Do not apply this product through any type of irrigation system, unless otherwise directed by approved supplemental labeling in possession of the user at the time of application.
• Do not use flood irrigation to apply or incorporate this product.
• Product must be used in a manner that will prevent back siphoning in wells, spills or improper disposal of excess pesticide, spray mixtures or rinsates.
• Do not apply under conditions that favor runoff or wind erosion of soil containing this product to non-target areas. To prevent off-site movement due to runoff or wind erosion:
- Avoid treating powdery dry or light sandy soils when conditions are favorable for wind erosion. Under these conditions, the soil surface should first be settled by rainfall or irrigation.
- Do not apply to impervious substrates such as paved or highly compacted surfaces or frozen or snow covered soils.
- Do not use tailwater from the first flood or furrow irrigation of treated fields to treat non-target crops unless at least 1/2 inch of rainfall has occurred between application and the first irrigation.
• Aerial Application: Do not apply this product using aerial application equipment unless otherwise directed by approved supplemental labeling in possession of the user at the time of application.
• Do not apply when wind conditions favor drift to non-target sites. To minimize spray drift to non-target areas:
- Use low-pressure application equipment capable of producing a large droplet spray.
- Do not use nozzles that produce a fine droplet spray.
- Minimize drift by using sufficient spray volume to ensure adequate coverage with large droplet size sprays.
- Keep ground-driven spray boom as low as possible above the target surface.
- Make application when the wind velocity favors on-target product deposition (approximately 3 to 10 mph). Do not apply when wind velocity exceeds 15 mph. Avoid application when gusts approach 15 mph.
- Low humidity and high temperatures increase the likelihood of spray drift to sensitive areas. Avoid spraying during conditions of low humidity and/or high temperatures. Do not apply during inversion conditions.
• Flush sprayer with clean water after use.
• Maximum Atrazine Application Rates Per Calender Year:
Maximum annual broadcast application rates for corn must be as follows:
- If no atrazine was applied prior to corn emergence, apply a maximum of 2.0 pounds active ingredient (3.2 quartsBREAKFREE NXT ATZ) per acre. If postemergence treatment is required following an earlier herbicide application, the total atrazine applied may not exceed 2.5 pounds active ingredient per acre per calendar year. Note: One quart per acre BREAKFREE NXT ATZ delivers 0.625 pound active ingredient atrazine per acre.
- Apply a maximum of 2.0 pounds active ingredient (3.2 quarts BREAKFREE NXT ATZ) per acre if a single preemergence application is made on soils that are not highly erodible or on highly erodible soil if at least 30% of the soil is covered with plant residues.
- Apply a maximum of 1.6 pounds active ingredient (2.5 quarts BREAKFREE NXT ATZ) per acre as a single preemergence application on highly erodible soils if less than 30% of the soil is covered with plant residues; or 2.0 pounds active ingredient (3.2 quarts BREAKFREE NXT ATZ) per acre if only applied postemergence.
• Maximum Acetochlor Application Rates Per Calendar Year:
Maximum annual acetochlor broadcast application rates for corn must not exceed 3.0 pounds active ingredient (3.8 quarts BREAKFREE NXT ATZ) per acre. Note: One quart per acre BREAKFREE NXT ATZ delivers 0.77 pound active ingredient acetochlor per acre.
• Preharvest Interval: Do not apply BREAKFREE NXT ATZ within 60 days of harvest of field corn for field forage uses or within 45 days for sweet corn forage uses.
• Postemergence applications of DuPont BREAKFREE NXT ATZ to corn must be made before the crop reaches 11 inches in height.
