You could do it before a frost too

Ideally I will time this just to get the effect of the product.

Unfortunately you’d be better off watching tele. I heard of a farmer who switched to liquid fert but forgot to tell the tractor driver ( or assumed he knew ) that he needed different nozzles. Said driver applied the fert with flat fans and it did a super roundup job initially, however the crop totally recovered ( from completely brown ) and went on eventually to yield very well.

That's why I'm going to go back and measure the regrowth.
Rolling post emergence of the crop, when you'd just bruised it, presumably?
I was spring rolling winter wheat and in my inexperienced and over-enthusiastic youth decided that I would then get the N on that afternoon - I looked like it had been glyphosate it scorched it so bad but did all recover

Why... we dont have a roundup addiction and it isn't a dangerous chemical so stop spreading sh!t
I had a similar experience once with one of my Canadian clients. I forget the exact rate but they applied UAN through flat fans onto 1-2 leaf maize (may have even been +Glyphosate, as Roundup Ready maize). Every plant was brown and crispy, I was convinced it was a write off...ended up recovering and doing just fine.

Ok, I'll reword. Roundup is political and, like other actives, is looking a bit shakey irrespective of the science. So I thought I'd try and see if there was any other way to kill plants using products that don't need approval as pesticides. There are no other available or pipeline inexpensive, systemic total herbicides.
The debate on our reliance of glypho around the world is a matter of academic record. Here's one for starters.
Trends in glyphosate herbicide use in the United States and globally - Environmental Sciences Europe
Background Accurate pesticide use data are essential when studying the environmental and public health impacts of pesticide use. Since the mid-1990s, significant changes have occurred in when and how glyphosate herbicides are applied, and there has been a dramatic increase in the total volume...

Think you will find this interesting Tesla...loads of this info in US where they obsess about salt loads of side by side at planting etc.
I think the answer might be to start with saturated AN or AS - little to choose between them - and then see how much KCl you can dissolve in it (ie stack the salt index of the two saltiest, useful products.)

Also can you please do a little exp with a latex sticker ie Bond / Pod-Stik......thanks

NVZ regulations may prevent use as a defoliant.

Ty I will read up on this.
I think as with much legislation, the key is what you put on the ticket sadly. Here I will be applying a registered fertiliser pre-planting of a crop and under its nmax. I regularly apply the same products pre drilling, just using different nozzles.

Praise the lord, I have a huge pile of this still in stock from the days when osr still grew.
I think there is a Frontier foliar N product that has pod-stick type stuff in which according to the marketing blurb supposedly forms a skin over the droplets to slow evaporation and reduce scorching. So try with and without

I do not know the legal situation, so my comments are just that, comments and observations. My understanding of the NVZ regulations would preclude an autumn application of nitrogen fertiliser as no requirement for autumn nitrogen. Any side effect as a defoliant would not trump this. But as I say there will be experts who know the correct answer.

Oh I see. Yes, closed periods and all that. Better wait until 15th Jan then.

Years ago we were asked by one of our contract applied customers to apply all the 200 kg/ha OSR nitrogen (28N with 5SO3 as A/S in those days) in one hit so he only had one application cost - we were silly enough then not to charge by the volume applied! It totally defoliated the crop, even using Dribble Bars, as it had a frost after it. However a week later those plants grew back stronger and faster than ever and with no long term ill effects! It could be used as a means of removing CSFB larvae from leaf stalks? Similar to grazing the crop. It was a well established crop mind you.
I just doubt applying liquid fertiliser as a defoliant would cut the mustard. You are trying to kill on one front yet add a growth promoter at the same time. And liquid fertiliser will only act on contact - no systemic action at all.
@teslacoils just for info urea solution is far less scorchy than an A/N and A/N/S mixtures so do not bother trying that. Trouble is straight A/N liquid does not stay in solution unless you keep it hot, it will solidify when cold, and at the point of atomisation from a nozzle it will cool so could be a problem at that point. Indeed this is how granules are made in a tall "cooling tower" where liquid A/N is sprayed into the top and the granules form as they cool and drop to the bottom.
Use a flat fan at high pressure to get as fine a spray as you can - small droplets scorch more. And as suggested by others, any added wetter, or mechanical damage prior to application, to disrupt the wax layer on the vegetation will help. Good luck and keep us posted.
BTW - NVZ rules do apply. Definitely leave until end of the closed period.
