Delta T is calculated by subtracting the wet bulb temp from the dry bulb temp
.Graph gives an idea tho. This concerns evaporation losses.
Maybe somebody more experienced might comment on the "hotness" score of your mix

Marketing guff. It is still 250 g/l trinexpac as an emulsifiable concentrate. The p*ss I being royally taken.
Dispersible concentrate, a new type of formulation. This formulation means you only need 75% of a moddus dose. It works better in the cold is more tank mixable and slightly kinder to the crop although it can still bite in the wrong conditions like any trinexapac. 0.15 of evo is v effective and you knowwhere it has worked. Marketing plays a part of course but a good product none the less.

Are you just trying to wind things up deliberately?? The UK is a bit bigger than just Somerset! It may well have rained over in your part of the country but we got nothing last week and haven't had more than about 1-2mm in one go since early March, desperate for a rain for the spring crops to keep them going and to wash fert in on the winter crops. Crops on lighter parts of fields starting to show the effects of a lack of moisture now with the higher temps in the last few days! We don't recon we have had more than 10-12mm in one day since at least March last year!

No I am not. People posting: 'applying a T0 or any PGR of any kind are off their heads' or similar is not helpful, in fact, for people who are not entirely familiar with the technical aspects of cereal husbandry comments of that kind made without any background or explanation are probably misleading. Many of these comments on this thread are made without reference to the region or circumstances involved. There is enough confusion for the average reader as it is, one could be forgiven for believing that fungicides are now apparently just for lining the pockets of multinational companies, and that bloody chlormequat is going to incinerate a crop that is exposed to 20 degrees.
I recognise that some regions of the country are habitually dry this time of year, I have no issue with that. But telling folk to just shut the gate or leave out any PGR this season is not helpful in my view. There are some farmers do not need much encouragement to forgo virtually any kind of agrochemical input and who do not understand the need for them as it is.
Ollie, your posts are falling into exactly the same category as the posts you criticize. We may be “habitually dry this time of year” compared to you. But this year for many regions it is not like a normal year, here the soil is dry throughout the profile after an incredibly dry summer, autumn, winter and now spring.
Put it like this, yesterday I put the first fungicide on my rye, but I didn’t put the planned PGR in. Would you put a PGR on a crop that is beginning to roll its leaves in areas with moisture stress? And that’s RYE!

Why did you put a fungicide on, did it need it or because agrono said to do it? I have not put any fungicide on anything this year including rye so I'm curious

You've said in previous posts your an agronomist and I think from this post you've just nailed your colours to the mast.
What you've said is pretty must word for word the guff I was told. Better formulation, kinder etc but what you didn't mention is although its only required at 75% of "normal" moddus as it's priced atleast twice as expensive as moddus and in some cases three times that of generic trineaxpac it still works out dearer so who's benefiting?????
Oh yer agrii and the agronomist of course and not the farmer.
Brown rust coming in. I walk my own crops.
The weather we are getting at the mo has brown rust written all over it. Last epidemic in April 2007-warm days & dewey nights. Nothing moves as fast as BR when it gets going. Those with no triazole/strob protection on rye & other BR susceptible vars should be having a look, before being quite so sure doing nothing is best! It is management of risk after all-and its your risk as the grower.

Been so dry and a week of frosts before this warm spell
T1 ctl plus epox
Save the sdhi for flag if desease looks like developing the weather can change and has before
The trials data over the last 35 years show in the 25 % driest years cheap protection of rust plus ctl is the only paying fungicide
If you have had descent rain in the last month then other options apply
No more growth reg with out significant rain in the forecast as n is not freely available to the crop

My agronomist loves PGR in general and Moddus in particular as much as you do.
All clients have been asked to ring him before starting T1 sometime this coming week.
Now that the rain is mostly off the forecast i GUARANTEE he will pull Moddus from all recs, despite it being on farm ready to go. This will be the third year in a row some or all of Moddus has been pulled last minute.
You talk about confusion. If you want confused put Moddus on a crop about to go into a bit of genuine drought stress. It may not go any particular shade of yellow, but it will stall out and stop growing.

Who is saying spray stressed crops with moddus? I am sure the technical bilge states you categorically should not do that. A bit of chlormequat is not going to torch the crop as other fear.
If the crop is that stressed then atlantis or SU chemistry will do it no favours either, especially at high rates.
I'd be more inclined to go with the fungicide and manganese at this stage if things really are looking poorly.

"Not stressed at all today, but probably about to be" is the call the farmer / agronomist has to make here.
But what good would the chlormequat do? Why are you putting it in? Will the crop fall over without it?

Some of us will get rain mid week if
the forecast is to be believed

Lucky you - this certainly wasn’t the case for most arable areas of the uk

Over 70 mm,this month,in North West Herefordshire .Think South Shropshire had the same. Very localised.
