New traits available for 2013 seedPosted Thursday, September 27, 2012, at 11:28 AM
Now that harvest is winding down for corn, you have some idea of what insect problems you experienced this past growing season.
While this is fresh on your mind, it would be a good time to note what problems occurred where. This will aid in selecting your hybrids for 2013.
There are several new traits that were available on limited basis or will be introduced for the 2013 growing season. Historically, the main pests in corn have been corn rootworm and European corn borer with corn rootworms more of a problem than corn borer. Corn borers are still around, but the overall population levels across the corn belt have decreased with the increased use of Bt hybrids. The seed industry is using multiple-mode-of-action traits to protect against these insects and reduce the chance of resistance developing. Multiple mode of action will also reduce refuge requirements and increased plant protection. It is also possible to plant these integrated products without also having to plant a separate refuge block with a non-Bt corn product.
Syngenta will have multiple mode of action corn-insect trait stacks readily for 2013 and 2014. Agrisure Viptera 3220E-Z refuge trait stack handles aboveground insects with dual modes of action for fields where corn rootworm management is not a primary concern.
It is providing a performance advantage with Agrisure Viptera in controlling cutworms and corn earworm. Agrisure Viptera 3220 E-Z is one of Syngenta's first 5% integrated refuge products. Agrisure 3122 E-Z Refuge trait stack offers two modes of action for both above- and belowground insect protection. It combines the Herculex I trait, plus Agrisure CB/LL, to control corn borer and the Herculex RW and Agrisure RW traits to control corn rootworm. Both products will be available from Syngenta's Garst, Golden Harvest and NK seed brands for the 2013 planting season.
DuPont Pioneer released three insect-protection, single-bag integrated refuge products in corn. These included Optimum AcreMax and Optimum AcreMax Xtra in 2012. Optimum AcreMax Xtreme was available on limited basis in 2012 and will be fully launched in 2013.
Optimum AcreMax offers dual-mode protection for above ground insects and Optimum AcreMax Xtra adds a single mode protection for below ground insects to the AcreMax product. Optimum AcreMax Xtreme provides dual mode protection for both above and below ground insects.
Monsanto in 2013 will be expanding its choice of Genuity SmartStax RIB Complete corn products, which provide dual modes of action for above and below ground insects. Monsanto will also offer Genuity VT Double PRO RIB Complete with dual modes of action for above ground insect control.
Both products will offer the ease of refuge-in-the-bag technology and contain a blend of 95% Bt corn and 5% non-Bt refuge seed.
