I was under the impression you could use arylex extremely late on cereals as well, around GS45 even? I wouldn't want to be doing that with ally or hormones.
Yeah, used it at gs30 on ww and spring barley with 1/2 ally. Did this because my local distributor had a shortage of straight fluroxypyr, and i didnt want to wait.
Pleased with the results, only about £0.50p acre more expensive.
Not sure about resistance management though, its a recommended mix from corteva.
