Optimum GLY is a new herbicide tolerance trait that enables growers to apply higher rates of glyphosate across a later application window. This offers greater convenience and flexibility when spraying for more effective weed management.
Optimum GLY unlocks the genetic potential of canola hybrids by allowing agronomic traits to perform without a herbicide impact on yield potential. Canola hybrids with the Optimum GLY trait offer improved crop safety with the ability to spray at the optimal time and rate, enhanced annual and broadleaf weed control to help with weed resistance management and herbicide rotation, and a later window of herbicide application (cotyledon to 10% flowering) to maximise weed removal options. This will help growers adapt to weather conditions and achieve better weed control through more choice and flexibility, keeping fields clean and maximising genetic potential.
A later window of application past first flowering gives canola growers more flexibility to time their herbicide application to maximise weed removal options. This gives more time to cover large hectares or clean up late flushes of weeds without the risk of yield impact on late-season applications.
Up to 3 applications, (rate range of 621 - 1080g ai/ha) of glyphosate can be applied per season, from cotyledon to 10% flowering. Apply up to 3 applications, at least 14 days apart. For optimum weed control, it is recommended to spray the amount of glyphosate that is required as early as possible.
Prior to taking delivery of your canola variety with Optimum Gly technology, you must:
Steps 1 – 3 can be achieved by accessing the Corteva Technology Agreement Centre (CTAC)
Accreditation is a part of the Corteva stewardship program and only needs to be completed once, prior to planting. This program is designed to provide farmers and agronomists with the information needed to successfully grow Optimum GLY® canola.
The TUA serves as an agreement between the grower and Corteva demonstrating that the grower understands and agrees to follow all stewardship and legal responsibilities related to their purchase.
All growers who wish to grow canola with Optimum GLY trait technology (regardless of whether the seed is for commercial, trial or demonstration purposes) must sign a TUA prior to purchasing canola seed with Optimum GLY trait technology.
Yes. All growers must have a signed Corteva TUA prior to purchasing canola seed with Optimum GLY trait technology, which is not covered by any other agreement.
No. All TUA’s will be signed and kept electronically via the Corteva Technology Agreement Centre.
Once you have signed your TUA, a copy will be sent to the email provided and will also be stored electronically on the Corteva Technology Agreement Centre, which can be accessed by logging back into the CTAC and downloading a copy.
