Complete options for weed control with Arylex active products

Four herbicides, based on Arylex active, are providing growers with options for weed control and use patterns, especially in winter cereal crops.

Paradigm, Trezac, Pixxaro and Rexade Arylex active from Corteva Agriscience, have been formulated to suit a range of different scenarios.

Corteva Agriscience area sales leader and technical specialist Ian Corr said the product line-up was designed to make sure there was an option for any weed scenario in winter cereals.

“We have options to get most of the spectrum you need, as well as having that selectivity and tank mixability to not cause issues in terms of compatibility and rotation,” he said.

The range of Arylex products have been showcased at the Corteva Agriscience facility at Breeza in northern NSW over the past few seasons.

In 2020, the Breeza site included the full range of products in tank mixes with other herbicides and across a wide range of cereal and pasture species.

“Paradigm is really forming into a mainstay product,” Mr Corr said. “It has a fantastic spectrum. It has great crop safety, selectivity, really good in terms of mixability. The mix with MCPA LVE, in particular, has really exceeded expectations.”

Paradigm is registered for post-emergent control of a wide range of broadleaf weeds in wheat, barley, triticale, oats, fallow and established ryegrass pastures.

Mr Corr said that, along with the cereal crop uses, the pasture registration was a great option for
livestock producers.

“It has a really strong fit for the weed spectrum in many pastures,” he said. “It targets the key weeds in pastures without having a detrimental impact on established ryegrass.”

Paradigm can be used to control volunteer forage brassicas early in the ryegrass phase and provide the base for long-lasting pastures.

“Controlling volunteers from brassicas, in previous crops, is really the key to success if you want a productive pasture that is going to last for a long time,” Mr Corr said.

Trezac Arylex active herbicide was launched in 2020 as a replacement for Hotshot herbicide and an alternative for metsulfuron-based tank mixes in many situations in northern cropping regions.

“Hotshot had been the mainstay for buckwheat or bindweed control,” Mr Corr said. “With the registration for Trezac Arylex active, we see that standard being surpassed.”

He said Trezac offered flexibility in terms of mixing partners and mixing partner rates.

“For small Bindweed, you can manage the rate of Starane down for six to eight leaf or for bolting bindweed you can still keep that rate up and get very robust control,” Mr Corr said.

“Aminopyralid in Trezac brings the additional residual control, widens the weed spectrum and compliments Arylex on many weeds.”

Trezac mixed with Tordon 242 is another option for additional spectrum on Deadnettle and other weeds without the antagonism and the plantback limitation of Metsulfuron and other herbicides.

“There is very robust volunteer legume control and some good residual on Milk thistle, based on the Tordon 242,” Mr Corr said.

“As we go further west, they are looking for more residual and we see Trezac fitting into those use patterns.”

Trezac is designed as a key mixing partner for the control of key weeds in wheat, durum or barley, in northern black soil cropping zones.

Pixxaro Arylex active herbicide is a new herbicide for the control of broadleaf weeds in wheat, barley, oats and triticale as well as knockdown control of broadleaf weeds, when mixed with glyphosate, in fallow situations.

Mr Corr said Pixxaro was particularly suited in fallow situations, as an alternative to Group B and G chemistries, for the control of marshmallow, sow or milk thistle, prickly lettuce, volunteer legumes and many other weeds in combination with glyphosate and other products.

“It is very soft on winter cereal crops controlling a range of problems weeds and has a short plantback period to canola, winter cereals and summer cereals,” he said.

Rexade Arylex active herbicide is a selective herbicide for post-emergent control of grass and broadleaf weeds in triticale and conventional wheat.

With six grass weeds and twenty-four broadleaf weeds on the label and good compatibility with other products, it offers a one-pass herbicide solution. Rexade is particularly useful for growers wanting to rest their Group A grass herbicides as wild oat resistance to those products increases in many areas. It also has a flexible application timing and short plant-back period.

“With our Arylex range of Rexade, Paradigm, Pixarro and Trezac, we really feel like we’ve got all weed situations covered in the northern cereal market,” Mr Corr said. “There is an offering to suit every use pattern.”
