Wheat pre em

[Mr Tree]

Morning

Presumably most are still planning on planting wheat in the next month or so.

With current prices and profitability what’s everyone’s thoughts on pre em choices and rates ?

cheers

Entirely depends on the weed spectrum/density/difficulty

Personally we have historical ryegrass and blackgrass in varying quantities.

Desnsity and difficulty seems to change each year !!!

Used luximo last season and not that much difference…

Just looking for thoughts on a standard program.

Different for each of those weeds imo. Fortunately enough I only really have BG in varying densities. I will base everything on FFCT, DFF and pdm and use Avadex and proclus as required. No fields in ww this year that require luximo I don’t think.

Seedbeds all rolled. With price of spray, I want to be drilling into moisture. Probably just maximum flufenacet. But I also have some stomp to use up. May do some autumn Atlantis to see if it adds anything after resistance results come back.

Some fields will have Luximo + Proclus fb Liberator + PDM. Some less.
Barley will be FFT,PDM,DFF and triallate based.

Blackgrass probably cost me 1 - 2 t/ha this year over all my acreage of wheat and barley. We are ploughing 40% this year, and using all the tools including late October drilling. Spring cropping not an option on a large proportion as too risky.

SUs have no effect on BG here.

Yeah, I'm mainly doing it as an experiment. I'm dubious about avadex, but I thought I'd do a split with avadex, nothing, and Atlantis used as preem . Lexus was always jolly good value, and I'm not sure that avadex is worth the money.

Ouch.

Fcct/dff + proclus + pdm +avadex as and where needed.
Follow up with fcct and perhaps defy as havnt used it for years.

It allowed me to get rid of an emerging black grass issue here entirely.
I can see that costs would be jaw dropping if you had to do the entire wheat area though.

2nd and 3rd wheats half rate Flufenacet, DFF and PDM. 1st wheat after OSR same, with a sniff of Defy.

Everything will be Direct drilled here this year.
Having had to create a fire break around the Linseed before burning, we could not believe seeing the massive increase in earthworms! Soils are in VG condition and as long as they don’t bake out, should DD well.
Predicted moderate rainfall should help.

Everything getting/has just had 1.5 l/ha Roundup Excel.
Pre ems will be:

Wheat:
3.6 l/ha Avadex Factor (Tri-allate)
0.7 l/ha Luxinum Plus (Cinmethylin)
2.0 l/ha Stomp Aqua (PDM)

Barley:
3.6 l/ha Avadex Factor (Tri-allate)
4.0 l/ha Crystal (PDM + FFT)
0.2 l/ha Sempra XL (DFF)

Bandur was a big mistake on the Barleys last year. Hence going back to Crystal DFF.

Can’t mess about in a year like this. It has to have the full works to get BG under control.
If heavy rain is predicted, I may well split the Crystal so as not to have it damage germinating seed in the drill slot.


Beans:
Nirvana is planned atm.

I think Luximo will work better with a wetter autumn. Too many dry cloudy seedbeds last year to do it justice IMO.

Defy (prosulfocarb) has the edge on ryegrass but needs a good dollop of flufenacet too.

I'm planning on returning to Avadex as we have a big blackgrass burden and it works OK if it is dry. I'm expecting the agronomist to write recommendations for a fairly big stack of herbicides again. Not much brome, ryegrass or wild oats as we throw plenty at the blackgrass.

A strip till drill doesn't help by disturbing soil at the point of drilling so we've been doing stale seedbeds already, helped by a wetter August and several generations of the damn stuff killed off already.

Avadex needs to be a feature where you have serious issues.

Not planting till the end of October onwards. We’ll have 2 x glyphosates between now and then. Pre-em will be luximo plus and stomp and post-em not decided yet.
If people keep drilling in September using min till techniques they will end up with resistant ryegrass like we have and then you are in another world of pain.

Your chem spend is about 1/3 of mine then.....

The real problem with ryegrass and some bromes is spring germination. Early drilling a non starter

 

[yellow belly]

Will use Avadex on most fields half its cost covers wild oats

probably use luximo plus pdm with dff wheat blw are a problem

plus 1 application. glyphosate

all notilled so only have surface germinating weeds all drilled in September

ryegrass is our thing, don,t think luximo bought enough to the party over liberator only a bigger bill!

Last year had to go back with topik post Avadex for w oats. Very disappointed.

Anybody tried or thinking of trying an adjuvant by Sangosse called Byte?
Costs about £3/acre.

Supposed to slow down the movement of pre ems through the soil.
Not sure of any benefits on Direct drilled stuff, but am open to suggestions.
