LIBERTY HERBICIDE

• Liberty herbicide paired with the LibertyLink trait is the only nonselective alternative to glyphosate-tolerant systems.

• Liberty is a contact herbicide with a unique mode of action (Group 10) that provides postemergence control of broadleaf and grass weeds, including weeds resistant to glyphosate and multiple herbicide classes.

• Liberty kills weeds in days vs. weeks.

• Liberty herbicide with the LibertyLink trait provides efficient weed management that enables nonselective and selective herbicide rotation.

Liberty herbicide with the LibertyLink trait is designed to be rotated with glyphosate-tolerant systems or as part of a LibertyLink/glyphosate-stacked program, making it an ideal option in modern cropping systems where glyphosate is used extensively. Unlike glyphosate, Liberty is a contact material and requires different application methods and timings. The efficacy of Liberty in a season-long weed management program is similar to glyphosate. Growers should practice responsible product stewardship by rotating modes of action to reduce the risk of herbicide resistance. A variety or hybrid containing both LibertyLink and glyphosate-tolerant traits offers an opportunity to use two different herbicides during and between crop years as part of an Integrated Weed Management program.

Liberty is labeled for use on all LibertyLink crops, including LibertyLink soybeans, corn, cotton and canola. Visual effects and control of weeds occur within two to four days after application under typical growing conditions. Weeds that emerge

after application will not be controlled. A herbicide tankmix partner may be added to provide residual or enhance efficacy. Carefully follow the use directions and label of the selected tankmix partner.

For best results, apply to young, actively growing weeds. Warm temperatures, high humidity and bright sunlight improve the performance of Liberty. In dry climates, take advantage of early morning humidity by making spray applications during that time. Additionally, spraying Liberty within two hours of sunset could result in reduced velvetleaf and lambsquarters control. Liberty activity is optimized when daytime temperatures reach at least 60 degrees and relative humidity is 30 percent. Apply Liberty at 15 gallons per acre (GPA) with nozzles and pressure that produce a medium-size spray droplet to ensure maximum herbicide performance.

HOW TO SPRAY

As a contact herbicide, follow application guidelines to ensure adequate coverage and maximum weed control.

1. Use nozzles and pressure that generate medium-size spray droplets.

2. Apply Liberty at 15 GPA of water; increase water if dense weed canopy exists.

3. Apply at groundspeed of less than 15 mph to attain adequate coverage.

4. Do not apply when wind speeds are greater than 10 mph.

5. Add ammonium sulfate (AMS) at 1.5 lb/A (8.5 lb per 100 gal) to 3 lb/A (17 lb per 100 gal)*.

6. Add tankmix partner, if needed.

Mixing Instructions:

1. Start with properly calibrated and clean equipment.

2. Fill spray tank half full with water.

3. Start agitation.

4. Add AMS to spray tank.

5. Add tankmix partner.

6. Complete filling spray tank with water.

7. Add Liberty herbicide and continue agitation.

8. If foaming occurs, use a silicone-based antifoam agent.

LIBERTY FOR USE IN A BURNDOWN APPLICATION

Liberty can be applied as a burndown treatment prior to planting or emergence of canola, corn, cotton, soybeans or sugarbeets.

Apply a minimum of 29 fl oz/A of Liberty for burndown of existing weeds prior to crop emergence. For best results, apply to emerged, young, actively growing weeds with a recommended application window of 14 days preplant to just before crop emergence. Biennial weeds, such as marestail, are easiest to control once they move out of the rosette growth stage and start to bolt (6 inches to 12 inches in height). In both conventional and glyphosate-tolerant crops, Liberty is an effective burndown treatment for weed control prior to crop emergence. Warm temperatures, high humidity and bright sunlight improve the performance of Liberty. Weed control may be reduced when applications are made to weeds under stress due to drought or cool temperatures.

In canola, corn, soybeans and sugarbeets: If environmental conditions prevent timely applications, a single burndown application of Liberty up to 36 fl oz/A may be made.

In cotton: If environmental conditions prevent timely applications, a single burndown application of Liberty up to 43 fl oz/A may be made.

Liberty can be used as a burndown or applied with a hooded sprayer to non-LibertyLink cotton for the control of glyphosate-resistant weeds, such as Palmer amaranth and marestail. Properly adjust hooded spray equipment and regulate tractor speed to avoid bouncing or exposing the cotton to the spray application. The spray hoods must be operated on the ground or skimming across the ground. Avoid operation on rough or sloping ground where the spray hoods might be raised off the ground. Raised hoods can cause injury or destruction of the crop. As with over-the-top applications, use nozzles that provide uniform coverage of the treated area.

* Research has consistently shown AMS improves weed control with Liberty herbicide. AMS is especially needed for difficult-to-control weeds like velvetleaf and lambsquarters under difficult environmental conditions (low relative humidity) or hard water.

NOZZLE SELECTION

Nozzle Selection vs. Drop Size Category

Nozzle selection is a process that maximizes product performance by managing the interaction between application volume (GPA), nozzle flow rate (GPM), nozzle type, operating pressure, travel speed (MPH), nozzle spacing (W) and droplet size category.

Nozzle Type Recommendations

The following examples of nozzles from four manufacturers are capable of delivering medium sprays when properly selected and operated.

• Spraying Systems: TeeJet® Visiflo® Flat, XR TeeJet® Extended Range Flat or Turbo TwinJet® Flat spray tips

• Greenleaf Technologies: TurboDrop® XL, TurboDrop TwinFan® or AirMix® spray tips

• Hypro: Guardian™, Variable Pressure™, Total Range™ or Albuz® AXI spray tips

• Delavan AgSpray: VariTarget™

Refer to nozzle manufacturers’ catalogs, tech sheets or websites for additional guidance.

• Spraying Systems: www.teejet.com

• Greenleaf Technologies: www.turbodrop.com

• Hypro: www.hypropumps.com

• Delavan AgSpray: www.delavanagspray.com

NOZZLE CALIBRATION AND SELECTION STEPS

1. Determine desired travel speed, nozzle spacing and application volume based upon equipment available, crop or weed size, and field conditions.

2. Use the equation below to calculate the nozzle flow rate required to deliver the required GPA.

GPM = Nozzle flow rate (gallons per minute per nozzle)

GPA = Gallons per acre

MPH = Vehicle speed (miles per hour)

W = Nozzle spacing (inches)

5940 = Constant

NOZZLE FLOW RATE TABLE

The following table contains the calculated value of GPM for the indicated GPA, MPH and W = 20 inches when using the aforementioned equation. Use the GPM calculated in the nozzle flow rate table and refer to nozzle manufacturer resources for nozzle selection.

All other crops 180 days

Key points to remember:

✔ Thorough coverage is essential to achieve maximum herbicide performance.

✔ Select nozzles and operating pressure that produce medium spray droplets and deliver at least 15 GPA. If a dense canopy is present, increasing the water volume and maintaining a medium spray droplet will also increase efficacy.

✔ Nozzle manufacturers provide recommendations for nozzles that meet the medium specifications of ASABE S-572 standard.

GPM = GPA x MPH x W 5940

Example: What size (GPM) flat fan nozzle is required to deliver 15 GPA when each nozzle is spaced on 20-inch centers and the sprayer is traveling at 10 MPH? What operating pressure is recommended to deliver medium spray droplets?

Use GPM = 0.51 to select the appropriate size nozzle from nozzle catalog, tech sheet or website. Below are some nozzles that will deliver 0.51 GPM to produce medium spray droplets.

• Visiflo Flat Fan TP8005 nozzle operated at ~41 PSI.

• TwinJet Twin Fan TJ60 – 8006 operated at ~29 PSI.

• TurboDrop XL TDXL11004 operated at ~66 PSI.

• AirMix AM11004 operated at ~66 PSI.

• Guardian 120-04 operated at ~66 PSI.
