Azoxystrobin & Take-all

I seem to remember that Amistar at T0 was helpful for crops in the 2nd wheat slot. Anyone care to comment on if this works and what the efective rate is? Last year was a bad year for 2nd cereals here and I have one field of wheat which I am keen to make perform after winter barley.

Will get rolled / early N etc, but was wondering if there was any actual evidence (not from manufactorur) about the chemical options?

You don't use or rate Latitude Static ?

Typically not a user. I know it helps but dont like the cost. After many years of going to see local trials, the data would say it was no better than putting the money into the bank for the one year you get it bad. This was a block that replaced some bobbins OSR, and I only had SPD dressed in the shed. And I have some Amistar in stock and seemed to think it was pimped as something that could help.

It's the least effective take-all measure and any benefit will be masked if you've already sown late, used Latitude and/or used a good dose of early N. If you haven't done any of these, or if you need every last % of control then it will give a benefit.

I think, like the use on potatoes, it needs to be used at a fairly high dose and washed in soon after application.

Ah, so the action is on the soil, rather than encouraging root growth then? I'm not expecting it, as we have done the usual "good things" ie decent nutrition, firm seedbed etc. But after last year's pee-poor 2nd wheat performance.....

You must either have the in laws visiting or no local hunt meet to attend or stuck in the rural depths of Lincolnshire with no pub to frequent on Boxing Day to discuss such matters. Clue us in the name, it will take every thing you throw at it one year in a while, just never know which year!

It's a fungicide so it needs to get to the fungus.

How about adding in some silicon wetter like Silwet with the Amistar to help push it into soil ?

I think that it would be worth while for Static to miss a bit in the field to see if the treatments make a difference ?

Over here on the coast Ami Opti is as good a t0 as anything. Especially if yr is a concern. Doubt it deals with TA tho.

Typically T0 is CTL +/- teb, so CTL + amistar is not overly different in terms of price for a trial.

Late drilling is the challenge - if it is cold and wet then root development from Nov sown wheat is going to be crap here. But was 12 degrees yesterday so I think we are in a very favourable time for fungus development. This was drilled 22nd October so not too early.

Thought it needed going on well before t0 to have any hope of an effect on take all.

I did a trial for Syngenta in the early 2000,s putting Amistar down the spout with the PPF system on a Horsch drill. We saw 0.4 t/ha average yield increase from a dose of 0.5l/ha IIRC.
I think syngenta reckoned on a half life of around three months after drilling, so some protection till after Xmas based on early October drilling. If I had a drill with that facility i would consider doing it again on known take all prone sites. It ought to be possible to soil map the fields and apply a dose to "at risk" areas with modern tech surely?
