Blackgrass chemical attack

I know there’s another general BG thread but this is just a particular question about chemicals.

Basically what are your ‘chemical’ approaches to BG. We aren’t doing a proper job so looking for ideas please.

I think as much FFCT as you are legally allowed plus Avadex would be my choice of chemical products. I used monolith last year on some tricky BG and was surprised how well it worked (mixed with half rate liberator) I don’t know how much the new chemicals add if anything.

I budget on 0.6 liberator and 0.6 pincer. How you apply them would be up to you.

Mainly, I aim to drill only when the date and weather would suggest the flufenacet won't have run out before Christmas. So typically mid October.

Avadex + liberator has worked well. I like to rotate the chem. Next year will be 360g flufenacet plus three litre of stomp.

And rogue all the time. With a napsack if needed.

Firstly dont drill to late and have patchy emergence as this will be worst case, I like to drill last week September 1st week October, followed by avadex and liberator. Then maybe a quirinus in November if neccacary.

Establish a good crop in mid-late Sept. avadex with the drill, full rate Crystal + DFF peri-em, rogue about now. mow/spray anything that can’t be rogued. Zero tolerance. Double or more spring break if required to reset.

I’ve found over the last 5 years that delaying drilling and fine seed beds along with full rate crystal and avadex applied on the worse fields has worked well for me. It the first time this year my agronomist has said I can start drilling a little earlier this year if I want. I have had zero tolerance on bad patches in the past, top them before seed is viable and spray off the re growth. This all works if the weather plays along with the drilling strategy. Sorry must add I go with liberator aswell if required or I can travel to get it on.

My approach is either full rate liberator or 50/50 liberator+crystal following an October drilling.
Then repeatedly knapsack any survivors with glyphosate May/June.
Wheats get cleaner and cleaner anything else (rye/peas/linseed) we go backwards on as can’t do as good a job with the knapsacks compaired to the wheats.

2 glyphosate applications pre drilling (mid Septemher FB a soil move and consolidation FB another one 24-48 hours pre drill)
drilling mid October onwards
Liberator 0.6 + Defy 3.0 @ pre em
generic FFCT/DFF 0.3 + Stomp Aqua 2.25 @ GS12/13

I have some wet places in sp.barley that are now heaving, was too dry for any pre-em to work anyway.
Suspect a 360 haircut may be best approach in these patches.

After all the cultural controls have been employed it’s all about a big residual stack here
Avadex and Crystal + DFF pre, Liberator post

Occasionally I use a bit of Pacifica plus and now I use it very little it does work a bit finishing off weakened plants, but it’s not something I rely on

Some Manufacturers trials here over the last few years have really shown the value of pre-ems

Last harvest one farm I do had the worse black grass I have ever seen. Autumn 19 was so wet little pre em went on and a crap March so Atlantis was late. This was such a problem 1 field was planted with Lucerne so that we don’t have to touch the soil for at least 3 years.

This year same land has the best control I’ve seen. For the 1st time ever I managed to apply glyphosate twice before drilling, I think this was key. Then crystal followed up with spring Pacifica.

Lots more roundup this autumn I hope.

Could a ‘Meat Tax’ be on the cards in the UK?

Written by Richard Halleron from Agriland

The latest machination coming from the so-called ‘opinion formers’, who seem to have the ear of government advisors in London, is the introduction of a ‘Meat Tax’ at consumer level.

This approach, it is argued, would have the combined impact of reducing meat consumption levels (I can really see the health benefits coming through now), while also helping to reduce the overall carbon footprint of production agriculture.

What absolute drivel! In my opinion, none of this makes sense at any level. This is a scurrilous and unfounded attack on livestock farming in this part of the world.

Yet, it has to be taken seriously. I make this point because economists at Rothamsted Research have already crunched the numbers where the introduction of a ‘UK...
