2019 t0

Colin · Mar 28, 2019

Just done alto elite, MN, cu, moddus. Rust and septoria evident, nearly needing a mildew spray as well but hoping it holds until later. Up here it's insurance to tide us over, next spray will be end April. However I'm also trying some areas that just get nutrients and pgr on a couple of different varieties to see how it goes. Trials up here show that a cheap t,0 pays and should allow lower spend later.

Soil tests always low in Boron and so are tissue tests.

Same here so trying some to see if it makes a difference. My soil man is always pushing it.

Jonathan Blake says reasonably consistently now that T0 don't really have impact on yield or disease. Citing info from Ireland where Septoria is rife he says they get little discernable benefit from it.

Personally even though I'm in Septoria central I'm not sure I'm going to do anything at the moment. Its cold in the mornings, dry all day, crops are growing fast etc....

If it did get a bit shitty and warm I could always change my mind.

And to get the T1 conversation started I can't really see a reason to divert from Aviator and CTL, unless it did get very dry or another SDHI is cheaper. Last year was warm and dry down here and my T2 was just a litre of CTL.

I used Aviator last year because of the catchy weather and their rain-fastness claims. Not sure if that was the right idea. From memory Adexar was actually cheaper per litre than Aviator and is a more powerful product, so I'd be choosing that for T1 this year. Have epoxi in the shed, and will add Imtrex from nothing to a good dose depending on weather.

For barley I'm wondering whether to go;

0.5 l Imtrex + 0.5 l Proline
or
1 l Siltra
(both work out same money)

A lot of trace elements seem to be going on. I've yet to see any quality, independent evidence to suggest any of them are worthwhile (on our heavy soils). Just because a tissue test says something is low, the key thing is what is the evidence that informs the validity of those tissue nutrient levels? I'll bet you could put trace elements on crops that test low on tissue tests and you'll get no response.

UK seems to have gone boron crazy! Not being divisive, we have used it at low amounts on cereals for years as high ph chalks & loams and obviously on beet and OSR. Tissue testing drives what we apply, and it is pretty much always the same-the soil does not change! Is this all serviced recommendation may I ask?? In response to testing?

Chalky clay soils here. 5 pre T0 tissue tests...boron 2.9-3.1 ppm, much the same as last year. 50% what they should be.
Are B and K given more consideration in areas fearful of drought stress? Probably

Agro recommending on winter wheat
0.5l/ha Eclipse (Fenpropimorph 250g/l; Epoxiconazole 84 g/l )
0.7l/ha Chlorothalonil
and growth regs + nutrients. Tempted to just do the growth reg and nutrients, what do people think?

John Slejpner · Mar 28, 2019

Looking at the forecast, its the next 48 hrs or bust for PGR's (too cold after)

What varieties? Have you a lot of mildew to knock down? Lot of fenprop in that Eclipse...
Personally i wouldn't use either active in Eclipse at T0, but Mantra at T1 still standard practice here (fenprop, epoxi, k-m strob)

Tissue testing. Always short of boron in both wheat and oilseed rape.

Do you still do Albrecht stuff?

Crikey... 1 litre of Siltra seems excessive!

What is Boron delivering at this stage in the crop?

Varieties are Santiago, Kerrin, and Gravity.

Rob, for WB T1, 0.6 Siltra should be plenty.

Siltravator??

Here today i will put a litre of alto elite on gravity and kerrin, and probably skyfall also. This will ensure it does not rain for the next month.
Montana will just get the PGR

1 CCC
0.1 Moddus
1 CTL
Manzi + Hi Mag

Involved with potassium in moving sugars around the plant. Low boron associated with reduced pollen viability and poorer grain set.
For some reason one is to try and avoid putting boron on a crop actually flowering.

Unless that's a typo, 1l of Siltra is way higher than needed. Given current weather conditions, 0.5l would be fine IMO. That's what we've done anyway.
