Anyone applied Glpho to cover crops when ground frozen but foliage dryish? say 11am?
Why?Yes but wheelings won't be controlled.
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 problemsYes but wheelings won't be controlled.
I've also experienced this, sprayed some stubbles early last year in the cold and wheeling didn't die...Yes but wheelings won't be controlled.
Thought glyphosate didn’t work very well in frosty conditions because of slow uptake.
Spray a bit on a wet lawn see what happensLeaf needs to be dry, or drying, to work IMHO.
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.Spray a bit on a wet lawn see what happens
It does take a while to work I admit. But it does alway work. I do mix it with a quality adjuvant.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.

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.It does take a while to work I admit. But it does alway work.

Never tried mixing glyphosate with liquid N. How does that improve its efficacy?Last spring I had a fairly hit and miss control with 4L 360 glyphosate, adjuvant and a bit of liquid N.

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.Never tried mixing glyphosate with liquid N.
