General thoughts/ preference's?

Our agronomist seems to want to chuck kitchen sink at it, t0 was epoxy 0.5/ ctl 1l. T1 epoxy 0.5/ ctl 1l plus full rate adexar then at t2 full rate ceriax!

Thoughts and opinions welcome?

We are still too far away to make the call, however boscalid based where eyespot could be an issue is a certainty

Still a week away from T0 here, don't think there will be 21 days between each one this year.

Epoxi at T0,1,2. I wouldnt like that.

1.5lt/ha Tracker here, with some extra epoxi to take it to "full rate", 1lt CTL. Or something like that. Havent seen prices yet, but my T1 will be based on 125g/ha epoxi.

We are looking like 2-2 1/2 weeks away from t1 here! Not huge amount of disease pressure about yet!

Having looked at a few crops this afternoon...I think we have missed T0 as some of the main tillers on our Deigo are at a good GS31...! I would post some dissected pics if I had not lost my camera..! But the crops all look very clean, no doubt a few more days with temperatures of 22C and rust will become more of a concern than septoria...

Your thoughts on Eyespot please, do you consider it to be a Major problem ?? or is it a good
commercial disease?? Sharp Eyespot?? I could be wrong.

Always control septoria, before it is a problem then control rust as and when..

Nope more of an emotive thing......certainly been well "sold" to farmers as it is this first thing some ask about, by the manufacturer not distributor I might add!.......one thing is a very high dose of Boscalid is required to reduce levels......stem base disease look low this year.....on rusty/low septoria varieties need to focus on foliar disease so other options come into play

Leaf 4 still only just tipping here so T0 mid end this week. Too early to call on T1 mix but will have ctl in it.

125g epoxi/ha is the full annual dose of triazoles in wheat, allowed in Denmark from this season....

Most agronomists here think it won't be a big problem most years, to keep the full season use below that level.
You must either have cheaper fungicides than we do, or get tremendous respons from those doses to spend all that money on fungicides?

We have tax on all pesticides, the level depending on environmental impact, to "guide" us to use the "correct" ones and in "sensible" doses. But since we as a nation didn't respond fast enough to these taxes, from this season we also have restrictions on use.

a 125g epoxi/liter product, will have a tax of 22£/liter which is more than 50% of the total price. Total price will be around 38£/liter.

Generic epoxiconazole is around £19 per litre. I wont use more than that per ha in a season, as I will use other azoles for later timings.

Here, if you use 125g epoxi/ha, you can't use most other triazoles at all in the same season as well. Prothioconazol and metconazol are not part of these restrictions, but all other triazoles are. That also means products with several ingredients are restricted. We only have 1 SDHI, boscalid, and for wheat we only have products containing that, mixed with epoxi, so we have to consider the full strategy before we start the season.

With these new restrictions was also a "guide" to only use the same type of product twice a year. If we fail to understand that voluntarily, that will probably be part of the next regulations. They really want us to grow resistant varieties and limit our need for pesticides by all means possible, rather than just buy what makes sense economical.

I dont want to use them if there is nothing to use them on. But I will be using an epoxi product for this timing, and will just tweek the rate and send back what I dont use.

I'd be looking at either no azole or just tebuconazole at the T0, epoxiconazole at T1, prothioconazole at T2, and metconazole at T3.

Prothioconazle is expensive. Metconazole less so. Expoxiconazole and teb are both fairly cheap now with epoxi at around £20/ litre, and teb £10 / litre.

I have actually never used prothioconazole before. I think the use in DK at the later timings is a toss up between that and boscalid, both mixed with epoxy. My agronomist has always favoured boscalid. That will change now, as Boscalid only is available mixed with epoxy for wheat, and prothioconazole is without restrictions right now. I will also use it this year. We only have 1 product with pure prothioconazole here, proline ec 250, and it is expensive. About £47/liter, with tax being £6,3 of that.

Epoxi was widely used here at all timings in the past, but we will have to change that now.

To answer the OP, T1 here is planned to be 0,2l/ha Ceando. But since it's probably a month away, that can still change.

Prothioconazole is around £44/litre here. A decent dose will do eyespot at T1 though my agronomist is favouring 0.75 Tracker + 0.5 Adexar + 1 CTL.

I haven't seen eyespot in a crop for years...

I think that level of product at your T1 is comparable to my planned T1,2 and 3 combined, which in most fields will be all it gets.

Adexar and CTL is illegal here. Tracker is widely used, but mostly from flagleaf-stage. Early sprays is mostly at rust and mildew with later ones almost only septoria.

Is it because you (as in british farmers) have very high levels of fungus pressure or because you have higher yields than us, that it pays to use these levels of fungicides? You must get greater yield-responses than we do to these sprays. I think average wheat yield in DK is about 7,5t/ha. I could be wrong though, as is varies some between regions.

So this is my point really are we as British farmers really getting the benefits of high fungicide spends and application rates or are we doing it because a salesman/agronomist has told us that's what we should use? After all anyone who sells these products will have decided months ago what products we will be using, otherwise they can not react or get any products in time if they wait and see how the season unfolds. So who is steering who here?
