If it's not resistant, why is it there?We have a patch of Ryegrass on one side of a field sprayed it for 2 years in wheat now in Rape still can't kill it,nothing has worked,tried broadway star ,axial and many others,Agronomist says it's not Resistant to sprays.
Ploughing ryegrass seed down works well, but leave it under for several years before ploughing again.
Yeh, needs leaving down for a while, ryegrass seed does die left under ground. It's not quite so robust as blackgrass seed.in WA I have heard of trials using moulghboard ploughs ( they had to import one especially, we just don't use them here ) to bury the ryegrass seed at a depth it wouldn't germinate from, with some success. However, I did here of one case where the grower was that pleased with the results achieved, that he did it again a few years later. Only to bring all those buried seeds back to the surface again . . .

It's not resistant to sprays?
Kerb in OSR or next time use clearfield?
Why is Clearfield better for grass weeds? Imazamox and the Dash adjuvant might tickle up grasses but even BASF don't claim any superior control from a Clearfield system in osr.

Defy is supposedly better on ryegrass. Also in maize there is dual gold.
