As thread title.
Extase?
Dawsum? (Kerrin!!!! × Costello)
I need to brush up knowledge on this, hence the thread.

If we lose Teb, what varieties of w wheat you planning to grow?

With COVID I've not been to a trials day in four years. So no idea.

are several that express good resistance to Yellow Rust. And certainly sufficient to be supported by other chemistry. Just will not be such a useful eradicant active available. And some to varieties to avoid. main industry issue is Group 1 varieties which have either weakness for Yellow or Brown rust. Be more important to be aware which varieties are starting to lose resistance to swap out of. While another valuable active there will be cultural solutions.

Plenty of information available without need to go to trials, although good social events.

I will probably just grow oldanddepressed...

Oh god I'd not want to go to chat to other farmers. Can't think of much worse. No, I like to see for myself tbh.

Thanks. Yes, I'd understood Teb had eradicant properties, but other chemistry was mainly preventative.
Vale of York, so I'm thinking in a normal year looking for rust resistance is more beneficial than septoria resistance. Obvs I'd Like both! but always seems to be a weakness.
All feed on one heap, unless I dare grow nothing but Extase.
Graham?
Retirement seems a good idea, although some legume fallow to follow this Autumn, so wheat it is. Dad is 80, so can't really get away with retiring before he does, but 40% stewardship has reduced peak time demands

Ones with an 8 or 9 for resistance
although I only grow them now is at all possible
yr may be easy to control but in a bad year it needs spraying every 3 weeks from t0 which is closer than the outer diseases need

Of tebconazole is endocrine disruptor, and we stop using it, can't really use excuse of depressed! (Not meaning to joke about depression tbh).
We have Graham and Champion in neighbouring fields. Last week while weighing up a T0 it was deemed not necessary on the Champion but the Graham was quite dirty.
Weather might change the rec as nothing done yet and its romping away.

Actually most of the varieties on the recommended list possess good resistance to yellow rust. As yellow belly says in his post go for resistance rating 7 and above, and maybe try to not have a variety with juvenile susceptibility as this may raise a false alarm. Depending on genetics and race development the resistance tends to break over time. Be more important to be ahead of this.
I've sown 96% Extase, with 3 tramlines of Dawsum as an experiment / potential seed crop.
And the former has looked better at every stage through the winter since the day it emerged. Lush and upright, versus thin and prostrate. The jury's out until it's over the weigh bridge.

Loosing Teb will be a huge blow, not only in Wheat but also for OSR and Beans too, I don’t have too many rust issues here so only plan to use Teb at T3, I use it more in OSR and Beans
Growing resistant rust varieties is the sensible answer, Elatus Era and Comet are the Chem controls without Teb, but inevitably they are more expensive products

When teb goes, which won’t be long, unless new milling varieties come through no one will be able to grow milling wheat. The gp1 varieties are too bad for yellow and brown rust.
the mills will need to accept extase or other varieties.
I’ve been labouring this point repeatedly to the board of our central store like a broken record but I think it’s really important that the mills realise the reality of the situation we are in. I will keep banging on about it!

It will go the other way, I would put £50 on it.
extase is extremely fast growing but doesn’t tend to yield anything special.
Dawsum is much slower, like its parent Costello. But tillers well and come may looks brilliant and has very good specific weight which is inherited from Costello.
they are my two main varieties. Dawsum for early drilling giving it time to get going and extase for later drilling second wheat as it romps out the blocks and seems to shrug off poorer conditions well. Dawsum drilled in that position really didn’t work very well. (All no till).

Will pyraclastrobin not sort it anymore? Used to be the standard for rust control
I’m not sure. Went all through worst case scenario at niab last year in a cpd meeting and the outcome for the worst varieties was basically don’t grow them

Depends. There are the strobes and Solatenol (as in Elatus Era) and a couple of the newer actives are reasonable. But they all lack the exellent eradicant activity that was found in epoxiconazole and tebuconazole. Do not always require eradicant activity but in the varieties with least resistance is often the case. So no exact answer.
