Titan AX is the first barley variety in the world to carry 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 by the University of Adelaide and AGT; with Titan AX being the first variety to be released.
Titan AX (tested as AGTB0325) is derived from widely adapted and popular variety Compass, a plant type that particularly lends itself to low-medium rainfall or Mallee style environments where early vigour and longer straw is preferred; and where lodging is less of an issue. However, AGT data suggests that Titan AX performs consistently well across a range of growing conditions and therefore should be a suitable option for all growers that see value in tolerance to Aggressor® herbicide.
Titan AX has been accepted into the Grains Australia malt accreditation program, with stage 2 malt evaluation planned for 2024. Titan AX is deliverable into the Barley/Feed grade.
Titan AX 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.

Commercial quantities of Titan AX may be available through AGT Affiliates, or your local retailer.
Titan AX is able to be traded between growers upon the completion of a License Agreement as part of AGT’s Seed Sharing™ initiative.
Titan AX is protected by Plant Breeders Rights (PBR) and all production (except seed saved for planting) is liable to an End Point Royalty (EPR), which funds future plant breeding.
Titan AX growers will be subject to a Growers License Agreement that acknowledges that an EPR of $4.55/tonne + GST has to be paid on all production other than seed saved for planting.
