PS - we used to kill ryegrass very successfully with 300ml / ha of 360 in the 1980's . . .

Grass the area out and silage it repeatedly.
There are few other ways to put the genie back in the bottle now it's out; apparently most farmers can f**k a ryegrass paddock in under 7 years - just copy their methods

We grew it for silage at home, so we were killing the regrowth, (after taking 1st cut off to plant corn ) always applied a hot mixture of Gramoxon ( Paraquat) along with crop oil concentrate. 3 pints per acre.... was quite well zilched , never had any survive that treatment

In the USA low rate on bigger weeds caused resistance plus multiple applications of one product on every crop
In the uk most of us use several different chemical mode of actions plus rotation
Plus some use cultivation or cutting
We all must be observant and spot new to the farm weeds when they first arrive not after control has failed
Spraying fertilising and combine operators should spot any new weeds
In the 1980s we had a field that had a patch of onion couch appear
spotted early and pulled out over the next 3 years no spray needed
Not seen any since
If you get a patch of rye grass assume it is resistant and do every thing to stop it before it spreads
We have triple r resistant ryegrass as tested by bayer. Pre ems in ww work great until the spring, then it all comes through regardless. Low disturbance drilling, spring cropping and all the herbicides you can think of in osr (cmax, Kerb, crawler) is a start.
Spring oats did a good job suppressing the rye grass. Unfortunately we have ryegrass spread evenly throughout the soil profile, so have adopted zero till in some areas, to keep seeds on top. Hopefully hitting with glyphosate whenever we get a chance. Our sp wheat, sp oats look fairly clean so far but if we throw the simba sl through it and try to grow ww we will end up with bad rye grass. Thinking of a very shallow pass with a carrier once to chit, perhaps a second pass to mechanically take out a few and chit a few more. Not sure. Maybe just stick with the uld/zt drilling.
