Its another bad spring for BG... I think many farmers are currently feeling the same. The dry september last year didn't chit much at all (huge amount of vol barley in wheat to prove that).We have a big issue with grass weeds and it’s getting worse. We are ok if we have a big spread of crops but it simply just doesn’t pay due to poor yields of spring crops such as spring linseed, spring barley, spring beans spring wheat. We’ve also tried grass but without our own livestock we get hammered on the selling price. We find ploughing isn’t helping and under Direct Drilling the problem is by far worse. Ryegrass, Blackgrass and Brome appear any time now in winter cereals and from late June in spring cereals. If we can’t grow cereals we might as well pack up.
We min tilled in the 90’s and 00’s and never had this issue. The soil movement got weed chits which we destroyed before drilling. We never used pre-em’s and just did a post em herb followed up with a clear up in the spring. Under DD we get a weed chit but I’m thinking we aren’t getting a full chit so when we run through with the direct drill seeding we are then germinating the dormant seeds that would of germinates had we moved the soil. We have used contractors with JD 750, Horsch Avatar and Horsch sprinter with Bourgault tines as well as our own Sabre Tine. They are all the same and germinate grass weeds. We have tried late drilling which does help but risky if it comes wet in late oct because then you can’t get on the fields. We’ve tried grazing a cover crop which doesn’t help either and is a loss leader without our own livestock.
So I’m thinking shallow min till disc and press straight after the combine, then spray off, then disc again and then spray off before a mid oct drilling? Anybody else in this mess?
Pretty much my whole approach.What have you changed?
Beans, osr and linseed are all crops we grow and the BG control in each of them is incredibly hit and miss from our experience and is basically pot luck. Abit like the massive variability in efficacy of cereal residuals year on year.Pretty much my whole approach.
Went from plough to mintill, that's where it really went wrong.
Mixing it through the profile is the worst thing to do.
Then to tine DD, was treading water with a few major hiccups in some fields, this was where I started heading down the point of no return with it, it either went well, or was a disaster.
Cropping changed also from wheat, wheat, rape.
To wheat rape wheat spring beans, this helped to a degree, until all chemistry in the beans was useless against BG.
Then added in a few spring wheats, this is where it went horrifically wrong in a couple of fields.
Untouched chopped straw overwintered, tine drilled spring wheat in, the BG came up faster than the wheat, badly.
Should have written it off but didn't.
It's taken me about 6 years to sort that cock up out.
Then gd drill purchased, further cropping changes.
I'll stick with the real nasty bits here.
Went winter beans, followed by linseed, followed by wosr, then a cock up with Jan drilled ww, then linseed again, back to wheat fir this year, almost clear.
I spot spray anything I see when travelling through.
Used avadex on the drill, followed by ffct etc.
It isn't vanity, it's pure common sense, where BG has a chance to get out of control it knocks seven bells out of the yields, chucking pots of money at it and not controlling it is madness.
It's better, and more sustainable, and profitable to have a good crop right through the rotation than to have weedy crops that have the kitchen sink chucked at them and still underperform.
I am seeing blw control reduce massively, it is intended to reduce the spend on BG, but it's got to be fully under control first.
Horses for courses, but I'd sooner not be contaminating the ground for the future.
Linseed I rarely have to do anything.Beans, osr and linseed are all crops we grow and the BG control in each of them is incredibly hit and miss from our experience and is basically pot luck. Abit like the massive variability in efficacy of cereal residuals year on year.
Sorry was thinking of winter linseed which we grew last year (never again) which was quite dirty, although the following wheat drilled mid september isn’t too bad.Linseed I rarely have to do anything.
I cover crop, graze off, burn off, drill.
Very little BG grows, if you plant late enough.
BG control here has taken a massive leap forward by not bringing anything up from depth, indeed all weed control has.
I've never understood the winter linseed job, the only advantage is early harvest, there's none of the late spring drilling BG control at all, and it doesn't have the chemistry available to control BG.Sorry was thinking of winter linseed which we grew last year (never again) which was quite dirty, although the following wheat drilled mid september isn’t too bad.
agree with not bringing more up. we have found if we have a made a situation bad we can get on top of it much quicker again compared to the constant burying and bringing up of seeds we used to do. I think leaving seeds on the surface is a really good way for them to either naturally degenerate or grow.
I did it to drill something early and harvest something early. The BG control does suck.I've never understood the winter linseed job, the only advantage is early harvest, there's none of the late spring drilling BG control at all, and it doesn't have the chemistry available to control BG.
I'd love to see plenty of sheep here in Suffolk, a county that used to have huge numbers of sheep in the "wool towns".Learn to love sheep, problem solved.
A concern if i start to use a stubble rake on larger areas... when the ground is cracked in august am I sweeping weed seeds into the profile?Mixing it through the profile is the worst thing to do.

We have had some pretty poor results from herbicides this year, some years they just don't work so well, easy to cry resistance but in many cases i think its simply down to weather and conditions before, during or after application
9 years out of 10 however I would say we get cleaner crops under zerotill than we did under min till
Get it tested if I was you. See attached. Defy no longer works as this test was a few years ago.
