Anyone applied Glpho to cover crops when ground frozen but foliage dryish? say 11am?
Spraying Glyphosate on the frost?

Why?
unless the nozzles behind the wheels arn‘t working they will be controlled just as well as the rest of the field, done this many times with no problems

I've also experienced this, sprayed some stubbles early last year in the cold and wheeling didn't die...

Gave it a go. Did a nice area, sunshine feels warm, came desperately close to getting stuck , so bailed now🫣
Thought glyphosate didn’t work very well in frosty conditions because of slow uptake.

i am largely on volunteer wheat ahead of barley, I would imagine it’ll do those well enough. There are actually some buttercups, (bad for them here), I am interested to see what happens to them… but not serious as I can deal with those in the barley… if I actually ever get some growing

Leaf needs to be dry, or drying, to work IMHO.
Spray a bit on a wet lawn see what happens
Since they banned the tallow amine part of glyphosate it's got much less reliable in less than ideal conditions.
I've seen it barely do a thing when plants aren't growing actively, and at 4 l /ha too.
Yet 2 litres in perfect, warm growy conditions work perfectly.
So I now only go when the plants are growing actively.

I’m sure it’ll work, but the point is to ensure good activity apply it when the conditions are in your favour, the active could be reduced down a bit too in ideal conditions.

It does take a while to work I admit. But it does alway work. I do mix it with a quality adjuvant.

More ideal than a wet or wetting leaf. It’s all relative.“ideal conditions “
Last spring I had a fairly hit and miss control with 4L 360 glyphosate, adjuvant and a bit of liquid N. The plants just went dormant due to the cold winds we had at the time, then came to life when it warmed up a bit. Normally the liquid N would be classed as supercharging the application, certainly wasn't the case last spring here.

i was just thinking… if it hadn’t been so bloody far from ideal conditions since the beginning of October, no one would be spraying glyphosate in January

Never tried mixing glyphosate with liquid N. How does that improve its efficacy?
It seems to really get it going. Many of the adjuvants you buy are simply ammonium sulphate anyway. Admittedly mine was a mix of urea,AN and AS, but I'd used it before with no issues, indeed it seems to get into the waxier leaves better.
It's only since tallow amine was removed it's got troublesome
