• Carries CoAXium® herbicide tolerance (Aggressor® herbicide)
  • A derivative of Rosalind with a similar plant type, offering a shorter plant structure and lower risk of lodging than the ‘Compass’ plant types like Titan AX
  • Wide adaptation
  • Quick-mid maturity, similar to Maximus CL and Rosalind
  • Similar grain size as some other high yielding feed varieties including Rosalind
  • FEED quality only

Breeders comments

PegasusAX carries tolerance to Sipcam Aggressor® herbicide (Group 1, Quizalofop-P-Ethyl), which allows growers to control susceptible populations of barley grass, brome grass, annual ryegrass, wild oats and other grass weeds in the barley phase of the rotation; offering an alternative to Clearfield® technology which growers have relied on for some time now.

Opportunistically discovered by Eyre Peninsula farmer Shannan Larwood in 2010, and further developed by the University of Adelaide, this novel herbicide tolerance trait has been bred into a range of widely adapted, high yielding backgrounds; with PegasusAX being released to complement its stablemate Titan AX.

Whilst Titan AX is in a ‘Compass’ style plant type (generally typified by good early vigour, a tall plant type more prone to lodging, and more suited to low-medium rainfall environments), PegasusAX is in a ‘Hindmarsh’ type background, offering a shorter, more compact plant type, and better suitability to medium-high rainfall environments.

Like it’s parent Rosalind, PegasusAX produces smaller grain. PegasusAX is a feed only variety.

PegasusAX has produced yields similar to Titan AX and Maximus CL.

CoAXium® Barley Production System

PegasusAX has been specifically developed to carry tolerance to Aggressor® herbicide. Aggressor® is a Group 1 Quizalofop-P-Ethyl herbicide, offering post-emergent knockdown of major grass weeds including brome grass, barley grass, annual ryegrass, wild oats, and volunteer wheat and barley (non-Aggressor® tolerant only).

Aggressor® herbicide has a wide application window and flexibility to be mixed with herbicides to control broadleaf weeds, with no carryover on soil or grain residue issues.

Distribution of Aggressor® herbicide and the CoAXium® stewardship program is administered by Sipcam.

CoAXium™ Barley trait purity testing service

If you require confirmation that your seed source is pure for the CoAXium™ trait (Aggressor™ AX herbicide tolerance) you can obtain a DNA-based PCR test on your seed sample.

To arrange your test please contact Intertek (the service provider).

Name: Rino Donato
Email: agritech.australia@intertek.com
Phone (office): +61 8 8301 1900
Mobile: +61 457 732 550

Please note there is a cost for this service, and you will be required to supply a clean 100g sample of your seed. Expected turnaround time is 1 month.
As a reminder, using Aggressor™ AX herbicide on your CoAXium™ barley every year is best practice to maintain purity of the CoAXium™ trait.
