Winter beans pre em

[dontknowanything]

Managed to get a field of beans in the ground yesterday. Not pretty, but better than nothing.

We normally wait 2-3 weeks before doing pre-em and glyphosate on beans, which would be propyzamide & nirvana. I'm sceptical though that the Nirvana will provide much of a benefit at the end of November - I mean how many BLWs will there actually be coming up at that time of year?

Nothing that propyzamide couldn't handle I suppose. But it must be applied within seven days of drilling.

I would get it on asap, with this weather you dont know that you will be able able to travel in 3 weeks and if you miss the boat on beans then your in a muddle.

Not a problem here, luckily.

What about the BLW that will come in the spring? I'm sure @Clive wouldn't bother?

You have Crawler post em for grass weeds but that doesn't really do any broad leafed weeds at all. If charlock or other cruciferous weeds are a problem the Imazamox will do them well & the residual effect should last a while at this time of year. As you say, there won't be much emerging for the next few months. Post em options are limited to bentazone + oil only for broad leafed weeds, which is expensive and not very reliable.

If it were mine, I'd do the Nirvana + clomazone (cleavers & hedge mustard) but I have a big broad leafed weed burden.

I tend to use straight PDM and clomazone with the Kerb. Does the imazazox add much? Another route I considered was adding some prosulfocarb instead of the PDM.

Really?
My agronomist here (who I don’t have a huge amount of faith in) said nivarna was no use on charlock...
I moved all my cropping plans around due to this as I was planning on my beans being where there is a patch of charlock.

The Imazamox drains your bank balance faster.

Difficult to advise the OP without knowing the expected broad leaved weed burden although my money says the bigger more problematic sorts arrive in spring anyway which is months away.

Imazamox is the ingredient in Clearfield that nukes charlock nicely. It all depends on the dose, timing, growth stage etc.

and how much of the nirvana is likely to still be around by then, in your opinion?

You could look up the half lifes.

Feels like we’ve had a metre of rain since I sprayed mine (beans just emerging now), which makes me wonder how much is around even now?

 

[Clive]

I've just gone with propyzamide and glyphosate - Nivana is expensive and like @dontknowanything not sure if it's adding much at this time of year unless weather is very mild

I wouldn't have bothered with the propyzamide but it's a cheap oppertunity in the rotation

not brave enough to do the no glyphosate thing again this year, although it did work I feel I may have been lucky with timing and with the weather as it has been I'm not feeling in the mood for risk-taking this season!

I’ve often read on here how unreliable bentazone is yet Jacob always gets good results. I do wonder how many operators are following the label recommendations of 300+ litres/ha or doing it twice at half rate?

I must confess to applying bentazone at 150-200 l/ha + a litre of methylated oil & it has mostly done the job unless the weeds were too big. I should really buy some bigger nozzles and accept the lower work rate.

I can't find a pesticide called Jacob. Is he handy with a hoe?

Jacob is my son / sprayer operator. I’ll let others on here advise you on the wisdom of suggesting that he might be handy with a hoe, especially to his face.

 

[Trial Officer Barney]

Any beans drilled around Oxfordshire/Buckinghamshire/Gloucestershire? Looking for 2 fields (at least 10 km apart) to place a small trial (approx. 800m2) on beans against BLW's. Recently drilled - not emerged and no pre-em on it (yet)
The Farmer compensation would be £400-£500/trial.

Got some winters drilled yesterday. Bucks / Berks / Oxon Border...........
