Wheat T1

[Hereward]

Static i might have to give up membership of the "Mantra at T1 - obviously" club, despite having it in shed ready to go.

For example Montana direct drilled 30th Oct continuous wheat. Not too high a seed rate as advised, it looked ok for its drilling date but absolutely nothing to get excited about pre first N early march.. .a lovely dark green and no visible disease of any sort is all you could say for it. Good disease scores so at least fung cost can be in the Siskin 60-70 quid bracket.
Or so i thought.
In march following N1 50 kg it went mad !!! Most other wheat i have stayed put or went backwards, but this Montana has its own plan and apparently it eats Beasts from the East for breakfast.
Now its plenty thick enough, the two pgr's in T0 (applied the evening the heatwave broke) are belatedly getting to grips with straw strength...and the alto elite wont have done much yet esp as YR not present.
But oh my golly gosh...what a shedload of septoria there is all over those leaves that were so healthy looking even a few weeks ago, as they stand, moddused to attention, rubbing themselves all over leaves 4 and 5.

Long day i'm rambling sorry.

Given decent disease scores and a very open crop stand at least till mid march, if montana has this much septoria where is everything else at? More or less the same.

This might be the one season in 10 / 20 or a generation where the "we don't do septoria we do yellow rust" mob might have to depart from past experience and react to what is in the field here and now.

On friday i meet agronomist and topic A on MY agenda is Mantra out SDHI in. Dave is not a fan of SDHI at T1 because he is independent, TAG influenced, and has never seen it pay on his patch.
This might be the year it DOES pay. (Here - i do appreciate in septoria land 2 SDHI is a no brainer)

I'll report back later how meeting goes

It's been a prefect start to a Septoria year, wet and then warm with many crops not having seen a Fungicide either by choice or lack of opportunity. So from where we are a robust SDHI at T1 is problem in order. Whatever plenty of CTL should be in the mix too.

So out of interest ...what do our friends in the south-west consider the best option for septoria at T1 out of the many available options????

A litre of CTL is a given....BUT as a quality CTL went on no length ago it could be omitted and kept for a T1.2 / 1.5 with whatever traces tissue test calls for - this would facilitate turnaround of T1 in catchy weather and may happen regardless. (Bittersalz and Krista SOP don't dissolve themselves in any great hurry)

If Elatus Era was already on farm for T2 (or that was the thinking at the time) does that change anything?

What rate are you including the Krista SOP and what timings ?

 

[John Slejpner]

What rate are you including the Krista SOP and what timings ?

5+kg ha all timings. 5kg a sensible limit if 5kg bittersalz already in the water...if using mag nitrate (which i am moving to but still have sulphate to use up) then i can put a bit more SOP in.

sorry for going a bit off topic here but have you ever done tramline comparisons with the SOP ? are you using it just on wheat or all cereals ?

My maths, from my prices make it £2.20ha saving over a litre of adexar.

If I save a quid an acre per fungicide pass in all my crops then I would be a happy man indeed.

Probably spending it all on muck and magic though. Foliar K.

Not sure how many intended to, but havent, got any Atlantis on, but plenty of starane in the mix too.

We did some Pacifica and Palio instead of T0 where there was a particular problem. Will mix some more Palio in to T1 to clear up what's left. Didn't have time to use Atlantis on fields that only had a smattering of black-grass. Probably wouldn't have bothered on these anyway.

half our wheats had Atlantis (using up some stock) and half Palio - looks to be doing a decent job and hope thats job done now re herbicides- I don't like mixing either with anything and like a higher water volume with them so do separate pass

Can Pailo be mixed in with t1? Got some late drilled exposed ground that, up to now, had nothing to target re herbicide.
Also does there need to be a gap between Atlantis and fung? Still half tempted to tidy up the odd headland here and there, but t1 will be next week and weather is poop at mo

Have been told we can as we put all PGRs in at T0. I think you can add two other products (fungicides in our case) on top of the Palio + ajduvant to be OK, but I would check yourself.

Palio will not get into the leaf if you mix it with chlorothalonil. Ctl will effectively form a barrier on the leaf surface. Unsure about mixing with other chems.

Oh dear. This is news to me. What about if you go round and spray Palio first and then come back straight away with the fungicide mix?

I have been told to give the Palio at least 6 hours before fungicide but ideally another day. Can’t do either with the wet or wind at the moment.

Agronomist has spoken to Dow who say you can mix Palio with Bravo (but not Bravo and Prosaro).

 

[solo]

Not very helpful when one agronomist has opposite advice to another. Hopefully the person at Dow has better knowledge.

 

[lincolnred]

Nobody seems to mention keystone for t1, The price seems competitive but is it not as active as some other sdhi fungicides ?

Bravo will slow the uptake of any other chemical in the tank mix, I would guess you will not get the best from the Palio in a tank mix with Bravo, but if it makes the difference between getting it on or not, sometimes you have to compromise.

 

[franklin]

Well, I have ordered mine now. :sheepish:

 

[B'o'B]

I've abandoned my plan of only 1 SDHI on at least half of my wheat and I'm poised to go either way on the other half.

Not as eradicant, so not a good choice if it's the first spray this spring. Otherwise fine.

Amazing the amount of discussion over a leaf that contributes up to 7% of the yield. Since the flag leaf contributes 50% + then the T2 thread should run to 50 pages
