BYDV

[T Hectares]

For those fortunate enough to have wheat established ( sorry to those who haven't!! )
What are you doing about BYDV??
I've not found any Aphids, I'm assuming they've drowned!!
It's been really mild but we had -4 and 2 x-3 two weeks ago, I really don't want to spray...

Thoughts please.

we will be doing the same as we have for the last 5 years, nothing. nature is the best weapon.
we only ever had very small areas affected by bydv it was the same when we used the insecticdes...

We are in the same position , Barley drilled 24.10 been pretty much blowing ànd raining ever since, on the odd sunny day we have the fieĺds are shining with cobwebs catching any aphids that might be around ?? But just had recommendations to spray for aphids with weed spray due to high risk of bydv !! but I'd sooner leave it out . Thoughts ?

The organic oats I grew last year had a few patches in a few sheltered spots, drilled two weeks earlier than my wheat too

Different weather though, we were under snow this week last year!!

Realistically there is very little you can do.

Yes you can spray early on but that isn't a guarantee.

All my wheat sown before mid October got treated in late Nov using the T Sum app. I haven’t treated the rest and will not bother unless I see foci of the virus.

No, trying not to use insecticides anymore. Haven't used dryer for 3 years before it was banned. These insecticides won’t work soon anyway so we need to build up the farm ecology and beneficials.

Deter!

Would spraying now not just be shutting the stable door after the horse has bolted?

No reports of aphids in crops, surprising given the mild winter, but if you have lots of cobwebs the spiders will have eaten any aphids around.

Bird Cherry aphids here in November.

Try that strategy in Cornwall and you’ll be losing crops to BYDV regularly. You are still right though.

Even beetle banks make no difference to crop pests that fly in en masse.

Here not sprayed for 20 years
september planted wheat October emerged not usually any bydv
when bydv came in the 80s we had mid September emerged wheat and barley
the predictors take out many of the aphids plus 97% of aphids do not carry bydv

In my view, if the weather isn’t or hasn’t been suited for spraying, you don’t need to worry about aphids too much (unless you plant early and aphids become established in a leafy crop and you don’t get in to spray them).

 

[texelburger]

I fear,here in the West,we may see a lot of BYDV. We're in a hot spot and aphids were migrating in the autumn.I don't think many crops have been sprayed.Time will tell.

I drilled WB in early Oct, not sprayed. If no severe frosts I will treat when I get chance. Later drilled ww won’t be treated.

I've done similar here,wb and wheat drilled in the first two weeks of october was sprayed for bydv with its herb in mid November.

Interestingly wb drilled on the 4th oct reached spray thresholds ,according to the ahdb aphid thingy on the 26th oct, 6th dec and again 15th jan.
Even stuff drilled in the second half of November reached threshold to spray on years day!!!!!
