Blackgrass after two year Spring break

It's supposed to be a cover crop. Black Oats and vetch.

No point spraying now though because the BG isn't hurting so it'll get 4 litres in March then no till linseed and then herbicides in the linseed. Then glyphosate pre harvest.

Then a cover and then linseed again.

Well that's the plan anyway.

I would roundup it now as there is enough growing to stop more from chitting, once they are dead another lot will grow.
 
So the experts view of two years Spring cropping will seriously deplete bg is wildly optimistic then.
It's a loads of bullocks.

The experts don't know anything about BG. One minute they were saying shallow tillage and multiple glyphosate passes, then they said ploughing, then they went Spring crops, then they were saying cover crops and now no till is the latest saviour.

They have to say something to keep selling things! It's their fault BG is around because they pushed everybody into ww/osr rotations because that maximised their income due to the inputs you needed to produce those crops.

They have absolutely no idea what they are talking about. How many experts actually farm land themselves and write the cheque's?
 
Blimey. Was control poor in the last spring crop or is that seed bank?
The situation in the picture is 3 yrs ago there was no BG. Last year we found a very small area (under half an acre) and sprayed it off. Then this year in the no tilled swheat it just appeared from nowhere across the whole field.

The field as said hasn't had any soil movement so all the seeds are on the surface at the moment.

Not sure why spraying now will give any benefit really? The plants aren't going to drop new seeds so we might as well wait.

The reason for spraying now is to remove the enzyme that is preventing more seeds growing.

I think the argument from the "experts" and some plant scientists is that once you have reached a sort of critical mass of emerged BG then it will suppress any further germination. From what I have seen I would agree with this as we have areas that come up like a lawn and as it grows it can all be a similar growth stage, but no fresh seems to come. We spray this off and more miraculously appears. This usually goes on for three kills before we have to drill if it's in with a winter cereal.

I don't agree with that. BG seeds will grow if they are there.

I think we are fortunate that all this seed bank is on the surface so the seed bank has now chitted.
 
Just walked our direct drilled winter wheat after spring barley and then spring beans which has had 4lt Crystal + 0.25l DFF and Avadex and there's still quite a bit of BG in.

Spraying off BG multiple times is not a good idea. There's no evidence to show that growing black-grass inhibits the germination of more black-grass unless you get so much BG that it actually shades the soil surface.
