Mateno® Complete Herbicide

The Complete Package to control a broad spectrum of grass and broadleaf weeds HAS ARRIVED!

Mateno Complete combines three active ingredients from three modes of action, including aclonifen, a new herbicide mode of action for Australia. Mateno Complete will provide residual control with flexibility in use rate and application timings to enable outstanding performance in a range of scenarios.  In wheat, Mateno Complete can be used in an early post emergence (EPE) use pattern which delivers weed control across the complete soil surface profile - in the furrow, on the furrow shoulder and in the inter-row. In both wheat and barley, Mateno Complete can also be used in an IBS (incorporated by sowing) use pattern.

Optimizing the timing of early-post-emergence (EPE) applications of Mateno® Complete.

Mateno Complete provides powerful control of grass and broadleaf weeds at the EPE timing, including weeds that emerge in the furrow that are traditionally difficult to control with pre-emergent chemistry.

Optimising weed control in barley with Mateno® Complete; guidelines for the best results

Tim Murphy, Bayer Market Development Agronomist, walks us through his small plot trial at Giles Corner South Australia, where Mateno Complete has been applied incorporated by sowing (IBS) in barley. Mateno Complete provides barley growers with an effective tool for weed control, where options are currently limited.

Mateno® Complete in disc-seeded wheat – considerations for crop safety & performance  

Angus MacLennan, Market Development Agronomist NSW, explains how to ensure crop safety with Mateno Complete in disc-sown wheat. Growers have limited registered herbicide options for disc-seeding systems, and Mateno Complete will deliver powerful weed control and flexibility advantages.

The proof is in the trial results

A new benchmark for annual ryegrass control

Mateno Complete representes a new benchmark in annual ryegrass control, particularly when applied early post-emergence (EPE) following the application of an effective IBS herbicide from another MOA group.

incorporated by sowing (IBS) control of barley grass

Mateno Complete applied IBS provides an improved level of control and reliability on barley grass compared to Sakura.

outstanding control of wild radish when applied early post-emergence

Mateno Complete provides a high level of control of wild radish when applied at the EPE use timing.

suppression of capeweed when applied IBS and control when applied EPE

Mateno Complete provides useful suppression of capeweed when used at the IBS timing, and a high level of control when applied at the EPE use timing.

Why has Bayer developed Mateno Complete? By combining three active ingredients, Bayer has developed Mateno Complete herbicide to provide a new tool that when applied IBS (Incorporated by sowing) gives class leading levels of residual grass weed control, the flexibility to use in wheat and barley and the ability to use knife point press wheel or disc seeding systems and when applied EPE (early post-emergent) gives broad-spectrum control or suppression across a range of grass and broadleaf weeds in wheat. 
What are the active ingredients in Mateno Complete? Mateno Complete contains three active ingredients; aclonifen, pyroxasulfone and diflufenican. Aclonifen is a new active ingredient in the Australian market.
Which Herbicide Mode of Action (MOA) Groups do the active ingredients in Mateno Complete belong to? The active ingredients in Mateno Complete are from three different Herbicide MOA groups; aclonifen (Group 32), pyroxasulfone (Group 15, formerly Group K), and diflufenican (Group 12, formerly Group F).
What mode of action does aclonifen have? Aclonifen has been classified as an SPS inhibitor. Currently it is the only active ingredient globally that is classified as a Group 32 herbicide. 
What does aclonifen bring to Mateno Complete?  Aclonifen is a herbicide that has activity on both grass weeds and broadleaf weeds and works best when in combination with other herbicides due to its synergistic properties. 
What does herbicide synergy mean? Herbicide synergy is the outcome of an interaction between two or more active ingredients that results in a combined level of performance which is greater than the expected outcome from the combination of the (known) performance of the individual active ingredients.
You’ve called aclonifen a synergist? What does that mean for Mateno Complete?
Synergy is complex and often involves two or more modes of action. Globally aclonifen has been recognized as a synergist in combination with certain other herbicides. Aclonifen has patented synergy in combination with pyroxasulfone and diflufenican, the three active ingredients that make up Mateno Complete. This means that when formulated together in Mateno Complete, these three active ingredients deliver a combined performance far higher than would be expected from the known performance of the individual active ingredients.
Is Mateno Complete available to purchase?  Registration for Mateno Complete is now approved. Product is now being produced and despatched. Contact your Bayer agent to order or for more details.
What will the price of Mateno Complete be?  Pricing will be confirmed prior to the 2022 season. Contact your Bayer agent for more details.
In what pack sizes is Mateno Complete available? 
Mateno Complete is available in both 10 L and 100 L packs.
In which crops can I use Mateno Complete?
Mateno Complete is registered for use in both wheat and barley.
Can I use Mateno Complete at different application timings?
Mateno Complete can be used at either the IBS (Incorporated By Sowing) timing in wheat or barley or EPE (Early Post Emergence) timing in wheat.
At what crop stage do I apply Mateno Complete when I use it EPE (Early Post Emergence) in wheat? Mateno Complete is active on weeds via both root and shoot uptake with the best results delivered when weeds are small (up to 2, 3 or 4 leaf, depending on the weed species) and good coverage of the weeds and soil is possible (to control current and future weed germinations). Mateno Complete must be used prior to crop growth stage Z23.
What are the application rates for Mateno Complete? Mateno Complete has a flexible rate range of 750 mL/ha to 1 L/ha when used in wheat at either IBS or EPE application timing.  When used in barley at the IBS timing, the application rate is 750 mL/ha. Under scenarios of high weed pressure, the higher rate should always be used in wheat with consideration of a suitable a tank mixture partner when using the 750 mL/ha rate. 
Which weeds does Mateno Complete target?
Mateno Complete targets a broad spectrum of hard-to-control grass and broadleaf weeds. Grass weed targets include annual ryegrass, barley grass, toad rush (a sedge), silver grass, annual phalaris, great brome and wild oats. Broadleaf weed targets include wild radish, capeweed, doublegee/spiny emex and prickly lettuce.
Can I use Mateno Complete at the EPE timing following Sakura applied IBS?
No. Mateno Complete should not be used in conjunction with or following the use of Sakura® herbicide, due to herbicide rotation guidelines, as well as potential crop safety, residue and recropping interval impacts.
Is Mateno Complete compatible with other post-emergent products?
Bayer has conducted a comprehensive range of compatibility trials with common pre-emergent and post-emergent herbicides, fungicides and insecticides and will be able to advise on their suitability upon registration. The use of higher water rates ≥80 L/ha can aid compatibility. The use of coarse inline filters (i.e. 50 mesh) can improve performance in sprayers.
Can I use Mateno Complete IBS with a disc seeding system?
Mateno Complete has a good fit for use in disc-seeding systems in wheat. Trials have shown comparable safety to existing pre-emergence herbicides currently registered or recommended for use with disc seeding systems in wheat. The product label outlines important guidelines for maximizing crop safety in disc-seeding scenarios. Mateno Complete should not be used in combination with a disc seeding system in barley.
Are there rotational crop restrictions with Mateno Complete?
Plant back restrictions are largely dictated by the pyroxasulfone component of the co-formulation, please see the label for full details.
Are all intended registrations on the current Mateno Complete label?
 A number of label extensions are planned for Mateno Complete, so the current label does not contain all the intended registrations. We will also continue to evaluate the effectiveness of Mateno Complete on additional target weeds and use patterns for further label expansion.
