T1
- Thread starter Feldspar
- Start date
As in taken down to the node then back up new growth? I didn’t know that was actually possible.

I dont think it will. As far as I'm aware chems will travel up the leaf towards the tip but not down the leaf to then move up the stem.

An option could have been to go with something cheap and cheerful like teb plus ctl to get some protection onto what was there and then go back after the rain when leaf 3 is right out and top it up or if your brave and the crop is clean wait for leaf 2 and top them both up with a T1.5.
Thats what I've done on some late december drilling after beet. The total combined T1 and T1.5 wont cost a lot more than a decent t1 and I have piece of mind if this weather continues for a couple of weeks.

This is exactly what I did on Monday. Ran round everything with 1l CTL because I had in the shed already. Some was due for T1 this week, some due next week. Seemed like cheap insurance - almost like a T0...or T0.5.
Now I have more chemical on the place I will now run round all of it again with teb and moddus, and possibly a bit more CTL on the backward stuff to hopefully protect the correct leaf once its out.

I think he means the septoria ?
a wet few days wont make a septoria epidemic, especially on gleam
but be prepared for the headlines in the fw

Yes, I meant I realised I didn't quite understand exactly how septoria pressure builds and spreads up the plant with the first lot of rain. Is the case that Tuesday's heavy rain means it has already spread up to leaf 3, or will that take a few more rains yet?

I spent Monday morning with plants all over the kitchen table dissecting like mad. Convinced myself that getting the fertiliser on was more important. Not sure whether that was right now. I hate the T1 timing. I always feel I've screwed it up slightly. In hindsight I should have pressed on faster with the rape when the rain appeared and then started with the earlier with the first T1 wheats.

Yeah our T0 went on last week on September drilled wheats, N2 today so T1 in a fortnight ish.

Don't worry about it. If you were writing for the famers weekly then you'd go mental but I'm sure you will have an opportunity in the next 10 days to get something on. If you feel its suboptimal conditions just try and whack some CTL on in between.
In field conditions are so different and variable. Just get it on when you can but lets be honest its been a particularly low pressure year til yesterday it won't magic into chaos straight away. Your flag leaf is still the boy and remember T timings are only an invention in the great scheme of things

Well I went over to main farm to get the sprayer and go spraying. Then realised I'd be up until 1am doing it and it wasn't practical to do half the acreage as it's a long way from base, so gave up and came home again! Let's hope you're right.

I’m sure it’ll be just fine. We can all rush around to fit our own self-imposed deadlines....but nature does as it wishes.
Still cool at night currently so that will slow any disease too.

So finally will have a chance to do the last of the T1 on Gleam that is probably 4 days late after 20mm of rain. Do I do 1l CTL and 0.75l of Ascra. Or ditch the CTL and do 0.87 l/ha Ascra (i.e. put the CTL cost into Ascra) for more eradicant activity?
The first choice
Today you found a window to apply?

When was that drilled (Extase)

Could have done it this evening, but will do the lot tomorrow.
