Spring barley fungicides

[MikeNeaverson]

It’s been a long time since I’ve grown spring barley, what are people using for fungicides and growth regs this year? Crop looks well with good potential

 

[robbie]

No growth regs here, I never apply them to spring barley but if your on fertile land or pushing it with lots of N then CCC+/-modus followed by terpal but that would be the extreme.
Fungicides 0.4 siltra or Fandango or prothio and strobe but they are all similar money, infact Fandango would probably be dearer for a weaker product.
T2 siltra, revystar, elatus or Fandango all similar money. Revystar is the muts nuts choice and will give ramularia control which may be important depending on location.

Is it any better on ramularia than ctl, I’m not convinced

If you’ve still got some ctl could I have some of it please!

 

[robbie]

No it isn't but we haven't got CTL any more so it's Hobson's choice.

 

[teslacoils]

A proline bixafen product is the way forward. Choice up to you.

 

[robbie]

Not much choice in that one!!!!! Especially this year

Nowhere near as good as CTL, which itself gave around 50% control at best.

My thoughts exactly.

 

[Northern territory]

No it isn't but we haven't got CTL any more so it's Hobson's choice.

My point was it wasn’t as good as ctl when you could use it so is it bringing much else to the party but higher cost

 

[robbie]

I agree but now CTL has become a distant memory it's the best(albeit not much good) we've got. If CTL was still about revystar wouldn't even be thought about for ramularia control.

Is it even worth bothering with it, the pounds spent versus control doesn't look very good,

 

[robbie]

Probably not but it makes some people feel better to know they've tried to do something about it.

The response to fungicides in spring barley is quite inconsistent. The loss of CTL for ramularia control has changed the game a bit.

Be aware that the recommended doses of some of the triazole + SDHI products are just matching the cost of the competition!

Isn't revystar the only chemical with similar efficacy to CTL when it comes to ramularia?

 

[robbie]

Don't think Similar but is the only one offering "some" control.

 

[Northern territory]

Probably not but it makes some people feel better to know they've tried to do something about it.

Yes I’m not trying to be antagonistic just interested on peoples views of revystar versus the prothio products

 

[Brisel]

Prothio is losing it's efficacy with repeated use, as expected with any single site fungicide. We keep needing new actives just to stand still in terms of disease control.

 

[robbie]

It seems rather daft and a bit scary when you look at the fungicide chart and see just how many are heavily relient on prothio but I suppose that's what they want now it's off patent is It to become use less very quickly so we have to move into the new stuff.

Prothio is losing it's efficacy with repeated use, as expected with any single site fungicide. We keep needing new actives just to stand still in terms of disease control.

Can’t disagree with that although in the case of ramularia I think they will only do it through breeding

 

[Gong Farmer]

Revystar is good on other barley diseases and gives an opportunity to avoid a prothio application. Not sure on the ramularia bit, it has reasonable activity but not at the doses appropriate for spring barley. Unfortunately this catchy weather is ideal for the disease.

Oh yes, then there's Folpet but I'm not going there.
