Or yellow rust?

Not alone. I Have seen same in September sown wheat in Lincolnshire. First spotted it thee weeks ago. Out of interest submitted leaves to NIAB for test, affirmative result arrived earlier today - not that I needed it. Previous years these crops would have been treated with Deter - but not last autumn - ta Mr Gove. Impossible to travel to apply pyrethroid insecticide until mid January.
When was yours sown. And when did it receive an insecticide?

You wish! If rust a whiff of tebuconazole reset the clock. That looks like BYDV to me.

Mascani oats, drilled on 27th September, no insecticide used. Previously always used Deter (Thanks Gove) and having read lots on here about not using insecticide, I thought I'd give it a whirl..... Wish I hadn't now. So far I've only seen it in two fields, confined to relatively small areas.

That makes sense - 27 September still in my view be a date when aphids flying. Your area is different to mine. Where I am I consider September sowings as vulnerable but from previous experience and observation the risk reduces here once we get into October and I generally am not concerned with anything sown after 8 October.
With a bit of luck your BYDV will be very small patches/foci confined to a small area. Keep letting us know how it develops. In which case it does support the forthright views on here of a few posters not to treat as you were literally just a few days to early sowing. And if you have been sowing Deter treated in previous years well into October then more area treated than necessary. But a complex picture and one where I can fully understand why farmers and agronomists treat more than is necessarily required.
Fascinating subject autumn aphid migration and BYDV infection.

Interesting. The other field I've seen it in was drilled 3rd October, which was the next field drilled due to 41mm of rain falling between 28/9 and 1/10. Maybe a blessing in diguise?

WB and WO are much more susceptible though? Or at least exhibit symptoms to a greater degree? @Hindsight will know. All I know is that I see BYDV symptoms most years in WB but rarely in ww.

don’t worry there’s the new bydv resistant wheat which I believe has been priced at “deter plus full programme and then some “

If the American GM model is anything to go by I am afraid you are most likely going to be proved right. We can't flog you chemicals but transgenic traits we can...

Is this a hybrid?

Couldn't travel with self propelled, so I did 3 20th sept sown fields with a 3m sprayer on quad bike.
Acres/hour wasn't very good, but I just might have gained myself £3-4,000 in extra grain sales that could have been lost to BYDV. Day and a half well spent?

I thought BYDV showed up red in oats?
