Frequently Asked Questions

Arylex™ is a member of what herbicide chemical family?
Arylex is a member of the Arylpicolinates, a completely new class of synthetic auxin chemistry within the Herbicide Resistance Action Committee’s Group O category. Chemical substitutions resulting in the addition of an aryl ring to the pyridine-carboxylate auxin molecules yielded a new compound with significantly increased herbicidal potency that paved the way for a completely new generation of lower-dose-rate, synthetic auxin herbicides.

What is the herbicide mode of action of Arylex™? What advantage does this offer to growers?
Arylex active is a synthetic auxin herbicide active ingredient that acts through a synthetic auxin (growth regulator) mode of action. With Arylex, farmers have an alternative auxinic herbicide mode of action to manage susceptible weed biotypes that are resistant to other herbicide modes of action, including acetolactate synthase (ALS) and glyphosate resistance.

What three unique characteristics separate Arylex™ from other auxinic herbicides?
Arylex mimics naturally occurring hormones by binding with specific auxin receptors in the cell’s nucleus. The pattern and level of affinity of Arylex to bind with specific receptors differentiates it from other synthetic auxin herbicides.

Another unique feature that makes Arylex™ active stand out among other synthetic auxin herbicides is its superior efficacy at low dose rates. Post-emergence use rates as low as 5 to 7.5 grams of active ingredient per hectare effectively control many common and invasive broadleaf weeds, including susceptible ALS and glyphosate resistant species.

One of the most advantageous qualities of Arylex is its flexibility for highly effective weed control across variable climatic conditions, even in the cold, wet conditions encountered in late autumn or early spring. Unlike most growth regulator herbicides, the activity of Arylex on target weeds is not significantly influenced by temperature, so control can be achieved under cold (inactive periods of weed growth) and warm (active growth) conditions.

Arylex™ can safely be applied to what cereal herbicides and why?
Arylex is rapidly metabolized in cereals to inactive metabolites. Complementing Arylex with a safener, such as cloquintocet, increases the cereal plant’s ability to metabolize the product, ensuring selectivity and crop safety over a wide application window.

Arylex can safely be applied to winter and spring wheat, triticale, durum, barley, rye and spelt.

When can Arylex™ safely be applied to cereals?
Arylex can be applied between early leaf development up to late boot growth stages in cereal crops.
