Rough looking barley

[Flat 10]

Winter barley. Glacier slightly worse than hyvido. Herbicide damage? Looking a bit like the spring barley l had that l put down to drought stress.

Rhynchosporium?

What spray has it had? A neighbour sprayed his barley early post em and that looks like it's had a dose of roundup.

Liberator pre em and some pdm/dff washing’s out of sprayer

What rate liberator. Was the seed well covered.

Full. I thought so. Bit cloddy. Not sure what ffct damage would look like, isn’t showing any dff bleaching type symptoms.

I think it's Net Blotch

Net blotch

Rhynchosporium

I'd go with net blotch too. Not worth treating in the autumn unless you don't like looking at it & fancy splashing the cash on something you'll never get your money back on.

 

[robbie]

I must admit, it does look more like disease than spray damage,but other than a bit of mildew surely it's to early for diseases to be present.

 

[Flat 10]

Didn’t expect disease this early..... I sprayed neighbouring barley stubbles off in an attempt to destroy green bridge but perhaps not soon enough

 

[robbie]

Was it ploughed? Could it be disease carry over from previous crop residues left on the surface.

I've got some non inverted barley after barley and its a bit yellow where last harvests swaths where but that's the toxicity of the chaff. Touch wood I can't find any disease at the moment but now you've posted about it I'll be keeping a close eye on it.

Looks like net blotch to me. See it in barley in the autumn from time to time. Not worth worrying about now, it's barley, the stuff is a weed. BYDV spray and manganese and leave it be, it can fend for itself. I have seen barley look a bit weather beaten before looks similar, probably a bit of both going on a times.

Ploughed after ww. 2nd cereal

It will have bydv and mang end of next week all being well

+1 for net blotch. Any seed treatment used??

Hyvido celeste trio, and glacier rancona from memory

If seed bed dry and coarse, you could consider adding foliar phosphate at modest dose, but it's your dollar.

 

[robbie]

I've often wondered about foliar phospate to give crops a kick start but what's it cost?

Very much depends on the product, who makes it and the dose. Yara, for example, make a fairly Rolls Royce product in MagPhos K which is a 3 (includes magnesium and potash) in one, if you only have smallish plants then you need only do half rate or something. It's not going to be £20/ha or anything.

It isn't the sort of thing I would blanket on every field every year but I've saved the life of a few crops with the timely use of this kind of product.

I don't know what trial data exists all I is my own anecdotal experiences of what I have seen. People who grow root crops or maize will have more insight into foliar products as they are more commonplace in those crops.

It isn't a replacement for good fertility it's just a way of trying to help a crop in distress if you like. A coarse, dry seed bed, second cereal, perhaps a lot of straw trying to decompose etc, you get the idea.

Obviously the land around me is not that kind, I will try to post some photos to show what I have been confronted with in the past and where I think this kind of product has a fit.

Very young for net blotch? what sort of weather you had?

Ant...
