Twisted awns winter barley

[Ormond]

What would cause twisted awns in winter barley. Had axial pro 2 weeks ago before awns appeared.....su to clean up some chickweed a couple of weeks before that. Could it be lack of boron?

Had this years ago, my agronomist suggested it might be drought stress, but I don’t think we ever got an answer

What does the rest of the ear look like?

I’ve got the same this year and it hasn’t had herbicide since early March. I’ve come to the conclusion it could’ve been late April frosts or a nutrient problem caused by the drought in April. The awns that were twisted appeared to be the first 5% that emerged which might point to them being earlier and coinciding with frost.

 

[Ormond]

Looks ok.....Just 10% of the heads have this curly hair thing going on

We’ve got a few in some Mountain, blind grain sites, I think frost is the culprit.

Curly wurly copper!!!!
Could be copper deficiency but considering the year we've had I'd probably be inclined to think it's drought and or late frosts.

 

[EddieB]

The top few awns on mine. I’m going for frost as the culprit here.

 

[cricketandcrops]

Ive got the same, late frost I think

 

[Clive]

copper ? i found this wheat plant a few weeks ago and twitter suggested copper (was only a single plant however)

 

[robbie]

Several years ago I had some twisting and blind grain sites in barley. My then agronomist thought it was late frost but ever since then I've used copper and haven't seen it since, maybe it's just a coincidence but I think foliar copper has helped.

 

[cricketandcrops]

Good point, I ruled copper out though as it had Gramitrel at T1 and also latest tissue results not showing a problem. We did have some hard frost last few days of April/early May

 

[Tractor Boy]

Yes I’m going with frost on mine as I’d put copper on at T1

Sounds like even though you have some distortion on the awns, you are going to have a crop. Spare a thought for the chaps that grew Torrent winter barley, (I think it was late eighties or early nineties). It was a very early variety, probably two weeks earlier than most, popular as an entry for rape and also with livestock guys because of high straw yields. We had some severe late frosts, that coincided with the ear moving up the sheath and most crops had blind ears and were cut for silage in the end.

Early 90s. The variety that brought baymv resistance.

 

[EddieB]

All of my Amistar winter barely was effectively wiped out by frost at flowering last year. Never seen it before, don’t want to again.

 

[Cordiale]

I don't remember that being reported in the press. The breeder obviously wanted it kept quiet!

Frost!!!

 

[robbie]

I think I'm right that sensation is very early like amistar ect, has anyone growing that had trouble this year????

1990. Apollo winter wheat was also badly hit but like Torrent it was the timing of the frost on an early developing variety. Ears were well up the stem and on their way out when a minus 7-8 hit.
