THE LIBERTYLINK TRAIT IN CORN

• A wide selection of LibertyLink hybrids are available from elite germplasm providers, including all Herculex®, SmartStax™ and Agrisure® hybrids with corn borer protection, as well as in-bag refuge products Genuity® SmartStax RIB Complete™, Refuge Advanced® powered by SmartStax and Optimum® AcreMax® 1.

• Complementary residual herbicides (such as atrazine, Laudis and Capreno), in addition to timely applications of Liberty, are strongly recommended in a LibertyLink weed control program.

• Using Liberty herbicide on LibertyLink corn hybrids delivers effective weed management and enables nonselective herbicide rotation, as well as provides excellent crop safety.

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

• Liberty kills weeds in days vs. weeks.

• Liberty has a unique mode of action (Group 10) that offers a nonselective choice for Integrated Weed Management plans.

• Liberty is a nonselective contact herbicide that provides postemergence control of broadleaf and grass weeds, including weeds resistant to glyphosate and multiple herbicide classes.

• Liberty can be tankmixed with most other crop protection products labeled for use in corn.

All LibertyLink corn hybrids have built-in tolerance to Liberty herbicide, while maintaining excellent crop safety, performance and yield. These hybrids are fully approved for food, feed and cultivation in the United States and Canada. LibertyLink corn is approved for export to many countries around the world. Today, this trait is widely available in high-yielding hybrids from elite germplasm providers. LibertyLink corn is ideal for U.S. growers, whether on rotated acreage or in aggressive corn-on-corn production systems to meet new demands.

LIBERTY UTILITY IN Bt CORN REFUGE

To preserve the efficacy of Bt corn technology, government regulations require growers to implement an Insect Resistance Management (IRM) plan. A proper IRM plan includes a non-Bt refuge planted in conjunction with Bt corn acres to prevent insect resistance to the technology.

When selecting a Bt refuge hybrid for any of the previously mentioned LibertyLink Bt hybrids, choosing a LibertyLink hybrid will allow you to use Liberty herbicide across the entire area, enabling you to obtain the full value and convenience of the LibertyLink trait. If a suitable LibertyLink hybrid is not available, configuring the refuge area in a separate field, or a contiguous block within the same field as the Bt hybrid, will allow Liberty to be used for weed control in the Bt hybrid area. It is imperative that the location where each hybrid is planted is clearly documented and marked, either on a GPS map or with flags or markers in the field to help ensure that Liberty is sprayed only on fields planted with LibertyLink hybrids.

For more detailed information on refuge options and acceptable configurations for specific Bt products, consult with your seed seller or Bt trait provider.

WHERE TO FIND LIBERTYLINK CORN

Herculex hybrids come stacked with the LibertyLink trait and consist of:

• Herculex I (HX1), which provides protection against European corn borer, Southwestern corn borer, black cutworm, fall armyworm, Western bean cutworm, lesser cornstalk borer, Southern cornstalk borer and sugarcane borer.

• Herculex Rootworm (HXRW) protects against Northern, Western and Mexican corn rootworms.

• Herculex XTRA (HXX) is a stacked trait that combines the aboveground insect protection of HX1 with the belowground protection of HXRW.

Optimum AcreMax 1 products stack the LibertyLink and Roundup Ready® herbicide-tolerant traits with an in-the-bag solution for corn rootworm refuge. Products consist of a blend of two different insect-resistant trait combinations (HXX and HX1) from the same genetic family.

• Only Optimum AcreMax 1 products have the LibertyLink trait in all components in the bag. Optimum AcreMax RW products do not have LibertyLink in all components in the bag and should not be sprayed with Liberty herbicide.

• Optimum AcreMax Xtra offers growers an option for a single-bag integrated refuge solution in areas needing both aboveground and belowground insect protection. Optimum AcreMax Xtra products do not have LibertyLink in all components in the bag and should not be sprayed with Liberty herbicide.

Agrisure hybrids with corn borer protection also come stacked with the LibertyLink trait and consist of:

• Agrisure CB/LL protects against European corn borer and Southwestern corn borer and provides suppression of corn earworm, fall armyworm and Southern cornstalk borer.

• Agrisure CB/LL/RW hybrids combine the aboveground insect protection of Agrisure CB with the belowground protection of Agrisure RW.

• Agrisure 3000GT is a quad stack that combines the aboveground insect protection of Agrisure CB with belowground protection of Agrisure RW, plus resistance to both glyphosate and glufosinate herbicides.

• Only Agrisure CB/LL, Agrisure CB/LL/RW and Agrisure 3000GT hybrids come stacked with the LibertyLink trait. Agrisure RW is not stacked with the LibertyLink trait.

SmartStax hybrids also come stacked with the LibertyLink trait and consist of:

• Herculex I Insect Protection technology and VT PRO, a second-generation, two-gene Lepidopteran-control product contained in Genuity Triple PRO, providing aboveground insect control for protection against corn earworm, European corn borer, Southwestern corn borer, sugarcane borer, fall armyworm, Western bean cutworm and black cutworm.

• YieldGard® VT Rootworm/RR2 technology with Herculex RW Insect Protection technology, which provides belowground insect control for protection against Western, Northern and Mexican corn rootworms.

• Roundup Ready 2 Yield® technology as a part of the Herculex system includes Liberty herbicide tolerance, providing broad-spectrum broadleaf and grass weed control.

• Genuity SmartStax RIB Complete Corn has the broadest spectrum of insect control on the market—with Roundup Ready 2 Technology and Liberty herbicide tolerance for broad-spectrum weed control.

• Refuge Advanced powered by SmartStax contains the Roundup Ready and LibertyLink herbicide-tolerant traits, making them tolerant to over-the-top applications of Roundup and Liberty herbicides.

1. Start Clean. Start with a clean, weed-free field by using an effective burndown application or conventional tillage.

2. Stay Clean. Be aggressive with early season weed management to avoid yield loss and weed escapes. Residual herbicides applied at burndown, pre-emergence and/or tankmixed in the first post application help ensure optimal weed management, particularly if environmental conditions delay timely post applications. Consider expected weed species and populations as well as environmental variables in the area when selecting a residual herbicide.

3. Scenario — Post Corn Emergence: a. Apply Liberty at 22 fl oz/A over the top of

LibertyLink corn when weeds are no more than 3 inches to 4 inches tall.

b. Apply Liberty at 22 fl oz/A on an as-needed basis following the first application at 22 fl oz/A. Planned sequential applications should be made 10 days following the first application of 22 oz/A.

4. Additives: Ammonium sulfate (AMS) can be used at a rate of 1.5 lb/A to 3 lb/A. Rates are dependent on temperature and potential for leaf burn.

“You have to keep the seed bank as low as possible in order to be successful with glyphosate-resistant weeds at this

level. My take-home point is this: proactive resistance management. Anything you can do to delay resistance

on your farms, do it by all means necessary.” -Larry Steckel, University of Tennessee

BAYER RESIDUAL HERBICIDE OFFERINGS

Bayer CropScience provides strong residual herbicide options—both pre-emergence and postemergence—to complement Liberty herbicide in a LibertyLink corn program.

Pre-emergence Herbicides: • Corvus (2, 27*) provides great flexibility and

can be used in traditional herbicide programs as well as in a program that pairs trait technology with a nonselective herbicide, such as Liberty or Roundup®.

• Balance Flexx (27) pre-emergence corn herbicide is an excellent setup product in a sequential program with Liberty herbicide. Using Balance Flexx as the foundation for a two-pass herbicide program gives corn growers an excellent combination of tough weed control and weed resistance management with crop safety and flexibility.

Postemergence Herbicides: Bayer CropScience also offers effective postemergence herbicides for a conventional program or as a tankmix partner in a herbicide-tolerant system. Postemergence residual options to consider:

• Capreno (2, 27) post-applied corn herbicide. Capreno has the longest-lasting residual available in a postemergence herbicide and combines two active ingredients for complete control of more than 65 grass and broadleaf weeds, including those resistant to glyphosate, with just 3 fl oz/A. Apply Capreno early (V1-V4) with Liberty to get the full benefit of a season-long residual.

• Laudis (27) postemergence corn herbicide, with its powerful weed control and unsurpassed crop safety, provides in-season, residual control in a tankmix with Liberty.

TOP 10 MOST FREqUENTLY SPRAYED WEEDS IN CORN

YIELD LOSS DUE TO COMPETITION

Research indicates that delaying a postemergence herbicide application until weeds are 6 inches tall results in a significant yield loss. Many factors come into play, such as weed species and the density of the plants present.

The bottom line is that not controlling weeds early in the season costs growers at harvest.

YIELD LOSS EXAMPLES

Early season competition from a heavy waterhemp infestation (more than 30 plants per square foot) reduced corn yields 15 percent by the time the waterhemp was 6 inches tall. With lower waterhemp densities (less than 10 plants per square foot), yields were reduced by only 1 percent when waterhemp was controlled at 6 inches.7
