Arylex is active at low use rates per hectare, does not accumulate in the stubble crop plants (in contrast to some other Group I herbicides such as clopyralid and aminopyralid) and it dissipates relatively quickly in soil, allowing rotational flexibility in most situations.

It was found that: glyphosate or glyphosate followed by paraquat did not provide commercially acceptable control on a widespread basis; residual chemistry clearly had a benefit with encouraging levels of activity from a range of herbicide mode of action (MOA) groups; double knocks of Group I herbicides followed by paraquat appeared promising and may be suitable where grass weeds are of less concern.  15/8/2018, Agronomy . • 2.
