Blackgrass after two year Spring break

Found this a bit worrying earlier. Field was Claydon drilled 1st Oct and sprayed with Vigon after rolling. 2015 harvest was Spring barley with no visible blackgrass after 2014 sugar beet with a few plants.
If it hadn't been drilled when it was it wouldn't have been drilled til Spring and I don't know with what. I was hoping two Spring crops would have prevented this.image.jpeg

No quick fix, just keep at it!

No, but most of it has built up where there is no Spring cropping at all. I'm not sure other than Spring barley what Spring crops are any good at out competing it either.
as far as 'competition' surely only grass? even then?.....other crops just allow cheaper/different chemistry really...don't they?

Grass would be good. I just don't know anyone with livestock, or how far it is feasible to cart silage to an AD plant.
would they want it?...if you've an ad plant maize would be a goer?.....if your land could take pigs?....i'dve thought outdoor pigs would be good for blackgrass as they'd be constantly turning/germinating/killing it?

edit...from the photo your dirt looks to heavy for piggies:(

Finding exactly the same. Worse after spring crops the only way I'm making real progress is through glyphosate in June in the standing crop

Yes. Too heavy for pigs, maize would be a disaster for soil health.

Spring barley seemed to work, but how many years in a row would be needed? Trouble with in crop glyphosate is where do you turn off!

Not sure I agree with Linseed - pretty uncompetitive crop with blackgrass in my observation. Spring Barley the kiddie.
Also after thinking will every body please grow S Barley and I should have mentioned Linseed is aweful to combine,
and yields aweful, bad to store, cannot control volunteers cheaply,difficult to dry, no market, the price will dive very soon,
I will re think my last post ;-) ,,,,

While linseed can be a reasonable break crop, unless fops and dims still work (which they don't) it may reduce seed return it won't prevent it.

Project Lamport 2020

  • 0

Project Lamport, now in its seventh year, is the UK’s leading R&D trials event. The original concept aimed to develop a cultural approach to blackgrass control, but has since evolved over the years. The site now explores improving soil health, as well as a comprehensive research project that investigates the impact of cultivations, compaction and cover crops on soil structure, organic matter and microbiology.

Expect weekly updates on Project Lamport, allowing you to participate in the entire journey rather than just the final product. These updates conclude with the official Project Lamport site demonstration and a live Q&A with our experts on the 15th of July.
