It is a synthetic auxin herbicide (Group O in HRAC classification), however it is the first member of a new structural class of synthetic auxins – the arylpicolinates. It has a unique binding site compared to other synthetic auxin herbicides.
The auxinic mode of action means that it controls weed biotypes that are resistant to other herbicide modes of actions such as ALS inhibitor herbicides, glyphosate and triazine herbicides.
Arylex offers farmers a number of benefits;
- A wide window of application (giving more spray days).
- It works on an extensive range of broad-leaved weeds and is highly efficacious (robust and reliable).
- It controls weeds independently of temperature (reliable).
- Rapidly degrades in soil and plant tissues giving maximum flexibility on cultivations and crop rotation (flexible)
- Very high levels of crop safety - even under tough conditions (crop safety)
Once in the weed, Arylex™ active displays a number of symptoms including cessation of growth, stem and petiole twisting, leaf malformations and chlorosis.
The symptoms of Arylex™ active herbicide damage to sensitive species normally occurs within a few hours. Plant death may not occur for several weeks, but symptoms appear in new growth soon after application. The speed of kill is quicker than ALS chemistry.
Arylex™ active has a favourable environmental and toxicological profile. In the EU it has met all the regulatory requirements (which include environmental and toxicological standards) for Annexe 1 approval.
Oilseed rape, winter and spring crops of wheat, barley, rye, triticale, spelt and sunflower.
Arylex™ active based products will work in all weather conditions though weed death may be slow under very cold conditions. Control is influenced by weed size with smaller stages of weeds more easily controlled. However, unlike most growth regulator herbicides the activity of Arylex on target weeds is not significantly influenced by temperature. This means that control can be achieved under cold (inactive periods of weed growth) and warm conditions with active growth.
