AXIAL^® Xtra

Q: What makes AXIAL® Xtra different from other grass herbicides?

AXIAL® Xtra is a purpose-built post-emergent grass herbicide combining two active ingredients - pinoxaden (50g/L, Group 1/A) and the crop safener cloquintocet-mexyl (12.5g/L) - with a built-in adjuvant system that improves weed uptake without the need for a separate additive.Key points of difference include:Crop safety - registered and proven safe in both wheat and barley, with the safener protecting the crop from herbicide activityTank-mix compatibility - stable, low-foaming formulation that works across variable water qualities and mixes reliably with broadleaf herbicides, fungicides, and insecticides without crystallisation or nozzle-blockingFaster brown-out - the built-in adjuvant drives quicker weed knockdown, reducing crop competition and limiting weed seed setResistance management - pinoxaden's distinct mode of action within Group 1 makes it a useful option where resistance to other Group 1 (fop and dim) herbicides existsFlexible application - apply between GS12–49 (two-leaf to first-awn stage), with a maximum of one application per crop; also registered for selective spray topping of wild oats to manage seed setFor growers and advisors managing grass weeds in cereals, AXIAL® Xtra offers a reliable, operationally straightforward option that fits within a broader integrated weed management program.

Q: What is AXIAL® Xtra and what is it used for?

AXIAL® Xtra is a post-emergent, selective herbicide registered for use in wheat and barley crops in Australia. It controls wild oats and phalaris, suppresses annual ryegrass, and can be used for selective spray topping of wild oats to reduce seed set. Its active ingredient is pinoxaden (50g/L), a Group 1 (A) herbicide, combined with the crop safener cloquintocet-mexyl.

Q: Which weeds does AXIAL® Xtra control?

AXIAL® Xtra provides control of:Wild oats (Avena fatua and Avena sterilis ssp. ludoviciana)Phalaris(Phalaris aquatica)Suppression of annual ryegrass (Lolium rigidum)For annual ryegrass control, it is important to know your paddock's resistance history before relying on AXIAL® Xtra as a standalone solution.

Q: When should I apply AXIAL® Xtra?

Apply AXIAL® Xtra when weeds are actively growing, between the two-leaf and first-awns stage of the wheat or barley crop (GS12–49). Avoid applying when weeds are under stress from drought, waterlogging, or frost, as this reduces efficacy. A maximum of one application per crop is permitted.

Q: Which crops is AXIAL® Xtra registered for use in?

AXIAL® Xtra is registered and formulated for use in both wheat and barley. The built-in safener cloquintocet-mexyl protects the crop from herbicide activity, making it selective to grass weeds while leaving the cereal crop unaffected.

Q: Do I need to add an adjuvant with AXIAL® Xtra?

No. AXIAL® Xtra includes an advanced built-in adjuvant system that improves uptake by grass weeds and promotes faster brown-out. There is no need to source and add a separate adjuvant, which reduces complexity and the risk of getting the mix wrong.

Q: Can I tank mix AXIAL® Xtra with other products?

Yes. AXIAL® Xtra is formulated for improved compatibility with a wide range of products including broadleaf herbicides, fungicides, insecticides, and foliar nutrients. When tank mixing with broadleaf herbicides, use the higher label rate. Some products can reduce efficacy - always check the current label compatibility guidelines or consult your agronomist before mixing.

Q: How does AXIAL® Xtra fit into a resistance management program?

As a Group 1 (A) herbicide, AXIAL® Xtra is best used as part of an integrated weed management (IWM) strategy rather than as a sole solution. Best practice includes:Rotating herbicide groups across seasonsCombining post-emergent applications with pre-emergent herbicides (e.g. Group 15 chemistries)Monitoring paddock resistance history and testing weed populations where neededFollowing WeedSmart principles to reduce selection pressure on any single mode of actionUsed strategically, AXIAL® Xtra is a valuable tool in a broader program - particularly in paddocks where fop-resistant weed populations are present.

AXIAL^® Xtra delivers wheat and barley growers improved activity on grass weeds such as wild oats and phalaris, without impacting crop safety. Designed to maximise application properties, compatibility and performance, AXIAL^® Xtra delivers exceptional results without compromise.

5 key reasons to choose AXIAL^® Xtra

Proven formulation, protected investment
Syngenta's patented formulation maintains full potency from storage to application - outperforming generics across Australia's variable water quality and challenging field conditions.
Superior grass weed control, even under tough conditions
Increased activity against Phalaris and Wild Oats versus other Group 1 (A) herbicides, with faster brown-out of treated weeds reducing crop competition and limiting seed set.
Complete, ready-to-use application solution
Built-in adjuvant system eliminates additional adjuvant costs and guesswork. Improved broadleaf herbicide compatibility enables flexible tank mixing to optimise spray timing and logistics efficiency.
Australia's leading ACCase resistance management herbicide
Integrate seamlessly with pre-emergent herbicides, helping to prolong “den” susceptible populations for a zero-tolerance approach to grass weed management.
Maximise spray uptime, minimise equipment downtime
Advanced formulation prevents crystallization, blocked nozzles, and excessive foaming - keeping spray operations running smoothly during critical application windows.

Frequently Asked Questions

What makes AXIAL® Xtra different from other grass herbicides?

add remove

AXIAL^® Xtra is a purpose-built post-emergent grass herbicide combining two active ingredients - pinoxaden (50g/L, Group 1/A) and the crop safener cloquintocet-mexyl (12.5g/L) - with a built-in adjuvant system that improves weed uptake without the need for a separate additive.

Key points of difference include:

Crop safety - registered and proven safe in both wheat and barley, with the safener protecting the crop from herbicide activity
Tank-mix compatibility - stable, low-foaming formulation that works across variable water qualities and mixes reliably with broadleaf herbicides, fungicides, and insecticides without crystallisation or nozzle-blocking
Faster brown-out - the built-in adjuvant drives quicker weed knockdown, reducing crop competition and limiting weed seed set
Resistance management - pinoxaden's distinct mode of action within Group 1 makes it a useful option where resistance to other Group 1 (fop and dim) herbicides exists
Flexible application - apply between GS12–49 (two-leaf to first-awn stage), with a maximum of one application per crop; also registered for selective spray topping of wild oats to manage seed set

For growers and advisors managing grass weeds in cereals, AXIAL^® Xtra offers a reliable, operationally straightforward option that fits within a broader integrated weed management program.

Will AXIAL® Xtra work on resistant ryegrass?

add remove

Annual ryegrass resistance to Group 1 (ACCase-inhibiting) herbicides is widespread across Australian grain-growing regions. AXIAL^® Xtra contains pinoxaden, which has a different molecular structure to many 'fop' and ‘dim’ herbicides and can be effective against some resistant populations - but it should not be relied upon as a standalone ryegrass solution where resistance levels are high. Resistance testing of your weed population is recommended before use.
