Blackgrass Herbicide

[ajd132]

Anyone trying anything slightly different this year?
Bigger stacks? Small stacks?
Avadex or no avadex?
Genetics or the proper stuff?

Or is it generally much of the same

Avadex.
Big dollop of flufenacet.

But mostly doing nothing until there is some soil moisture.

Mainly trying to work out where the 2 or 3 days are where BG germination drops off a cliff and going after rather than before, no doubt I'll cock some of it up as usual!

Avadex flufanacet
Fine spray nozzles. None of those air inclusion things.
200 litres water
October drilling

Atlantis still works here but always try to save it till the spring

I’m also not convinced about those air inclusion nozzles

Gone for .6 pincer(generic liberator) any field/patches with a history of BG will get .3 pincer and 2L of crystal.

I do the opposite. Always before Christmas if possible.

There's nothing wrong with air inclusion for pre ems, but I do use 200 litres not 100.
Indeed I like the angled ones for better coverage.
More hits the ground instead if blowing away in the force 10 gale most seem to use them in.
Round me the worst BG fields are done using flat fans, loads of drift, high booms, ignoring high winds.

I won't call it delayed drilling, its just a sensible drilling date, mid October onwards, better in all ways, less BG, less BYDV, less diesease, less Take-all, less lodging etc.

IMO better to spend money on a big drill that works in the second half of October, than pallets of herbicide, insecticide, fungicide and PGR's.

All the black-grass trials I visited this year advocate drilling from mid October onwards.

As for herbicides,

Pre-em: Liberator + Avadex Factor

1-2 leaves: Atlantis + Flufenacet (Atlantis still gives 50-60% control here, also covers Wild Oats and many Blw including cleavers if autumn applied).

With a much smaller area to do, I'm hoping being able to pick my days for drilling and spraying will do as good a job as upping Chems. While applying during a light drizzle is supposed to help, I've found as soon as soil sticks to the tyres I get more BG in the tacky wheelings.

Forgot to say alternate angled nozzles

And 25cm nozzle spacing and lower boom height

And good sprayer capacity with obsessive operator (me)

Good article. She sounds eminently sensible.

I'm hopefully trying to replicate last years results

Mid Oct drilling into shallow tilled seedbed
Avadex,ffct,pdm and dff in the stack
No contacts

Worked so well this year I really have to do the same again...

What products are you using. Named main brands, generic, or individual actives and making your own?

I'm lowering the rate of Liberator to save some cost but keeping the DFF rate up as broad leafed weeds are an issue. Seedbeds will be moist and we won't be starting until October given the forecast. I've been running full rate FFCT for years & the brome seems to be better. A few known bad fields will be getting full rate Crystal + DFF. Branded Liberator is more keenly priced these days so I will probably go for that. Hurricane seems to be the preferred form of DFF with a sensible formulation. I do not believe that some of the generics are the same quality as the branded material. They have to save cost somewhere to compete.

No Avadex or big stacks here - by the time it gets that bad we should be changing the system towards more spring cropping as the previous methods clearly aren't working.

It's a job for this week to look into the residual order, but probably Crystal + hurricane and Liberator, the group has keen prices on the main brands and seeing as they are formulated to work together and come in one can, I'd err towards them...

I was thinking about using individual actives and making my own but only worked out about £1.25/ac cheaper, going for pincer and adding crystal where needed.

I'm at that stage now. Avadex on all w barley and any suspect wheat ground. Full pre em etc.

Still controlling blackgrass with this approach but realising maybe the game will soon be up.

Spring beans and spring barley after cover crops going in on 20% area for the first time.

Aiming to stay ahead of blackgrass, grow some protein for pigs, improve OM levels and reduce soil disturbance

Flufenacet at maximum rates are the cornerstone of our control. Today’s rain is a very welcome addition to the equation. All of our wheat ground is ready for the rapid, but previously pretty dry. Today’s rain means l’ll be able to wait for the first flush of weeds and drill into ideal seedbeds. Seedbed quality has a much greater impact on residual performance than application technique IMO.
