Looks highly suspicious of blackgrass to me, happy to be proven wrong though.

That is Blackgrass, !
Should have been winter wheat, hopefully spring barley soon.
Bad blackgrass field, lots of it and boy does it grow. I know its been a mild winter but that could have a head out in March? Any autumn drilled wheat that hasn’t been sprayed for blackgrass this spring is going to struggle to work now?

Bit of a silver lining then.
That depends on when it established. Blackgrass here varies from the growth stage of your picture where it germinated nearly as soon as it hit the ground on undisturbed soil to early emergence in stubbles sprayed off in late February that will need a second glyphosate dose pre drilling. I'm glad to say that plants in wheat, barley and osr sown last autumn here are not that far forward.
Would it be fair to say that the plant in question is on land undisturbed since harvest?
Killing blackgrass in stem extension is very difficult indeed. Even with glyphosate!

its coming S Barley!
Thanks. I should read the post better!
Still hard to kill though. What would you do with it?

Er I think 4lt/ha of glyphosate has a reasonable chance of drawing this thread to a close.

4lts of 360 in 150 lts to be applied in a LEGAL breeze, bigger target..

I personally would not recommend someone spray a stubble with just that in it at 4 litres. 4 litres is generally enough to kill off full blown grass leys that have root systems, not piffly little weeds in stubbles.

Your opinion, blackgrass needs a good dose when starting to run is my opinion, and not being argumentative but you were not 100% sure it was blackgrass earlier in the thread!!

Been a very long time since I went to look for a blackgrass plant (2015 and counting)!
