Spraying T1 over the last few days and its obvious the blackgrass control isn't as good as I first thought.

Last year seemed an easy year here, felt like I was in control, this year looks like normal service is resumed.

This weed really is driving every decision on the farm now.

We are the best we’ve been in years.
A couple of let downs is a few scratched tilled fields drilled beginning of October, the adjacent fields in the same block have much less which we no tilled.
Apart from the odd bad patch on some fields I’m really pleased.

How much flufenacet are you using?

One full dose (is that 540? I can’t remember off the top of my head). We didn’t follow up with the extra this year but probably should have done on those few fields. Not putting anything on spring crops so as not to over use it.

Full rate Liberator or Crystal is 240g.

You can go above 240g flufenacet by using the generic straights/mixes.
Think it's legal to 480g. Don't quote me though, I'm hazy, not an agronomist and currently have some weird bloody viral infection which has me floored so could be remembering wrongly

What kind of money would you guys estimate black grass control costs / ha

And just how much does it knock the average yield ? - can’t help but notice the farms that seem to have it worse often seem to be the same ones that claim high average yields ?

£60-100/ha for winter wheat which sounds a lot and is a lot. However many will be spending that on spring barley also which we don’t bother with as it’s usually too dry and knocks the crop.

Anything from 70/ha upto 120/ha on bad fields, probably an average of 100/ha here?
A bad infestation will decimate yield to zero then you’ve got years of weeding aswell.
The odd plant scattered about is ok for a year or two but it soon multiplies!
But pretty good control again this time except a few known problem areas that are being flagged whilst doing t1 for either rogueing when I get motivated or knapsack ..!!
