I'd spray that, otherwise it will be well into September till those greens are fit.

We have been grappling with this problem. Bulk sample is testing at 12% but there is a lot of green in it. Some questions I would love answers to:
1. If you put glyphosate on before the optimum timing for the regrowth, what happens to those grains in this instance (particularly with respect to malting quality)?
2. If you cut it with the greens still soft and pulpy in with a lot of fit grains so that overall the moisture is fine, what happens exactly? They equalise in moisture with the surrounding grains OK, but do they actually dry to be something a bit like the fit grains, or is their makeup completely different as a result of being cut too soon?
3. If you do cut with greens in and don't put air through, what happens? I have some wheat with green that started to go a bit solid, and felt hot and clammy. Can the moisture of the bulk sample go up? If so, where does this extra moisture come from? If it can't do this, does it just heat up? What is generating the extra heat?
4. To maximise the chance of getting malting quality presumably the best option is to wait for the green stuff to completely ripen? But then this could take so long that the fit stuff loses quality.

These are all very good questions and I'd second a request for an answer!!

I am no techy but I have wondered if this is a job for a drone with a camera and some optimisation software to decide spray timing. I have walked all over my spring barley and changed my mind about 46 times as to whether/ when to spray it in the end going with gut feeling that best to leave it as we are on sand that burns up pretty quickly anyway given a few hot days. Now we have a strong NE breeze that maybe doesn’t look so clever as the very ripe heads are starting to look precarious. I’d dive in with the combine but it’s land locked with greener stuff and don’t fancy a tank of silage cutting a way through to it. Hey ho.

When malting premium was much higher I had uneven ripening and waited till early September till the greens were ripe
made malting
if the greens are harvested too early they can reduce the germination
but with malting premium low it is not a big loss
unless this year the n level is also high on all the droughtEd low yielding crops and the uneven crops give variable germination
currently cannot find wheat ripe enough so waiting for that
barley not ripe enough either
still only 9 August

Just drive through it without cutting? Or will this tip your business over the edge?

If waiting until September what were the losses under the cutterbar?

What rate of glyphosate are people using. Iv been recommended 1.5 litres of 360, or 2 if there is any weeds. Does 1.5 sound a bit low??

I never use under 1000g of active. Plus wetters / conditioners.

The product label should show recommended rates. You do not need big rates to turn a crop that is already halfway there. Different if there is weeds or couch in it. The more important thing is that you follow the harvest interval to the letter.
That is the correct rate, most labels will say 1 l/ha for pre-harvest management where grass weeds are also present and 1.5 l/ha where broad leaved weeds are present.
If Couch or other weeds are the target pre-harvest then the label will allow 2-4 l/ha depending on levels of weeds.
7 day interval for Cereal crops before harvest regardless of rate.

I think if you have grain on air floors you will be ok if you manage it for a few weeks. If not it’s going to require moving with a bucket or a stirrer. Or drying after harvest. Green grains are hitting Hags.

But really, seven days is a waste of time. Wants two weeks easily to do any good, beyond tramping the tramline greens anyway.

Having a similar when to spray dilemma with wheat and oats. It will no doubt rain for a week as soon as I make the call! I am not keen on pre-harvest glyphosate but not much other option this harvest having not applied any herbicides this year and with such uneven crops.

If in doubt get it on. Times a tickin. I'll do oats end of this week.

Ordered enough round up this morning to do the lot . Sadly the green bits show no sign of catching up naturally in a sensible time. All over the shop, every combination of greeness and ripeness you can imagine.
Ploughing has exacerbated the problem by drying out the sand causing early ripening then secondary regrown and delaying germination on the clay so it has first tillers still green. Direct drilled spring barley is better and more even.
Most of the direct drilled.february winter wheat is shite also with 50% regrowth. Best bit was direct drilled in January after rape and previously a grass ley and looks almost respectable.
Tbis is the year that kills slow draining but drought prone farms. Turdliest year ever.Still another fortnight before we harvest anything by the looks of things. A thunderstorm or two would put the top hat on it.

I might need to add a drier rather than a wetter to the glyphosate tank mix...
The monthly outlook they are really hedging their bets..
"17-23rd August. Around this period, high pressure is likely to be near to the British Isles, or out to the northeast over Scandinavia. This should bring plenty of dry and settled weather, perhaps with multiple sunny days for many parts of the UK...... There is also the risk that low pressure is instead more influential right over the British Isles, bringing unsettled weather more widely across the UK"
About as useful as writing "17-23rd August, expect British weather. Best to confirm actual weather on the day using a weather stone"

This is our spring barley. Even the early germinated bits some way off glypho. Luckily it is only for own feed use.

not a lot more that year but all made malting
this year who knows if we avoid this weeks showers losses will be low
