Wheat T1

[Steevo]

1.0 Aviator + 1 CTL + 1 3C + 0.1 Freeze (trinexpac) + magnesium, copper & zinc

How many applying close to a litre of Aviator are mixing CTL with it?

CTL is so cheap feel free to put it in however you like.

Interesting point this. There has been quite a bit of discussion previously about antagonism between Aviator and CTL.

Is that still considered the case?

I've never had a satisfactory answer to this. In my opinion, Bayer are supporting Aviator + CTL because they would struggle to sell much otherwise. CTL is a key component of a septoria control programme and this will not change.

I'd agree with this. Even to the point that Bayer are intentionally ignoring any potential antagonism. There is one person who might know..... @Mike@Bayer might be able to set the record straight.

As you say, CTL is so key that if it were possible you'd think they'd reformulate and then have a HUGE announcement about it. All costs compared to ignoring it though.

I guess some firms might use that to allow them to sell Boogie Xpro + folpet instead!

 

[robbie]

Any rust risk? What variety? 1st or second wheat? Previous crop?

Proline + CTL would improve eyespot control but is weaker on rust. Tracker would do both nicely but keep rates high in this unsettled weather

Diego second wheat after spring barley so big rust risk. As you say proline is weaker on rust over epoxi so I think tracker is the weapon of choice but d you think a litre Is enough.

My understanding is that Bayer accept there is antagonism between Aviator and CTL.

I think they state not to mix Aviator with CTL at T2 because of reduced "kick back" on leaf 2 which is a vital part of the T2 timing.

However, they are "happy" to include CTL with Aviator in a T1 situation because it is working mainly in a protective situation without a great need for kick back to leaf 4.

I personally wouldn't be using Aviator + CTL on a late applied T1 when leaf 3 has been exposed for a long time in wet weather.

Agree with this ^^^^^
I'm planning up to 1.25l of Bugle (imtrex) + 0.5l Cortez +1l Ctl , total cost £38/ha.
I think I need a strong eradicant, bearing in mind the weather and no varieties have REAL Resistance.
Normally get away with Cortez and Ctl at T1 -won't be good enough this year, or Aviator on dirtier varieties, but the antagonism is a worry this year so don't want to use it.
The triazoles aren't going to do much for me (not worried about eyespot or rusts) so why pay for expensive prothio ? A litre of Aviator +Ctl would be £37/ha but I think my mix is stronger and more flexible, I can alter the dose on the day. Probably consider a T1.5 of Ctl as well, if the pressure remains.

 

[Zippy768]

Leaf 3 about half emerged in late Sept sown Siskin here. Very high disease weather though. I'm glad I put a T0 on leaf 4.

I am glad and relieved I renegade on my previous decision not to do a t0. Phoew

The used to say the Ctl reduced the curative powers of the aviator. .

Here earliest drilled wheat, so 5 to about 15th october, is pretty much all starting to show leaf 2. Kerrin to a lesser extent than Skyfall and Gravity.
Given the urgency of T1 therefore, what are peoples thoughts on spraying in non-ideal conditions? Especially into / onto a falling dew? ie midnight not 7am

Moddus .15 a litre of mantra and CTL

I wouldn't rely on mantra now, especially if you think T1 is urgent. Put an sdhi in there and wait to spray when conditions good. But don't think a dew will matter especially with ctl in the mix and mantra is a very good formulation

I'm normally reluctant to "recommend" rates as that is best done by the BASIS registered person who walks your crops, not some bloke you're talking to on the internet. 1 litre of Tracker gives you 62 grammes of epoxiconazole which = half rate Opus/Cortex/Rubric which is not enough in the West Country. If you want my keyboard agronomy opinion then a litre of Tracker will do your eyespot coverage and rusts but is not enough on septoria & you should top up the triazole dose with a straight or SDHI blend.

 

[franklin]

62g of epoxi and 233g boscslid is not enough chem for me in the east.

What sort of money is adexar and aviator this year?

 

[franklin]

Aviator £166 for five litres.

 

[yellow belly]

will be going with a t1.5 here on early developing wheats basset which is one of the first to leaf 3 emerged
leaving leaf 2 unprotected in the hope that sdhi has enough kick back is too big a risk
because if sdhi resistance does build up we will only know about it when it is too late to save yield
the spend is the same just an extra pass through in mid may but saved a pass in march with no t0
net result no additional cost but reduced risk win win all round

have you already done T1 ?
T1 here not done & with rain & rain forecast T1 is looking like being a T1.5 !

 

[Case290]

wheat far to thick Diego & far to tall
1lt chlormerquate .2 moddus at t0/ t1 any body giving there's another .1 moddus at t1.5 with 1 lt chlorothalonil . Or will that over do the trinexapac.

 

[franklin]

T1 on earliest wheat here won't be for a week to ten days. Maybe a fortnight if it goes cold again.

 

[Crabtree]

What sort of money is adexar and aviator this year?

Aviator £165/5l
Adexar £310/10l

Can save a bit mixing your own adexar, and therefore up the SDHI rate more cost effectively.

Looking at the forecast, it won’t be going on for a week here, was hoping to get some on tomorrow but now gives more rain!!

L3 over 50% out and no T0 on Lili, Barrel and Mulika!
