Thickening a liquid

Remember the croptex glove for chemically hand roguing wild oats from wheat?

Never got my hands on one:-)

There were no wild Oats on the home farm and I used to sort them in Winter Beans on the outlying arable.

I've not used it extesnsively, just a few occasions around my lot. I found that the recommended dilution had no effect on the woodier plants to upped the does to 5% iirc. A couple of months later, all the woody brambles just tipped up and died, for good. Marvellous stuff.

5% solution. If my maths is correct thats 20:1, no ?

Thats the dilution I always use. Kills brambles eventually but as they are still dangerous even when dead, so have to be cut out anyway I prefer to cut them back to the ground. They grow again I know but I gain great satisfaction from emasculating them. One tripped me up last week. Fell flat on my face and cracked a rib. I think they may be fighting back.

They are just biding their time...

Yep. Iirc, the packaging said 3% to start with and I ended up with 5% (or perhaps 8%), it wasn't a hugely expensive or highly concentrated exercise to find the sweet spot which killed them off.

Bleedin' Triffids, they are.

There are/have been chemical sprays intended for woody plants. The EU has caused some to be withdrawn.

The place to look is..

Grazon was a good one.

Broadshot?

Roundup kills brambles . At 10* normal strength. On the leaves.

[Tim Lamb]

Maybe. You are supposed to avoid killing the top growth without leaving time for the chemical to translocate to the roots.

[Tim Streater]

AIUI, some plants just take longer than others to get offed. I carried a sprayer across the lawn a couple of weeks ago, without realising it was dribbling. Now I have an unexpected brown path across the lawn.

By contrast, take japanese knotweed. 15 years ago there was a clump of it, which, not knowing what it was, I had dug up and the bed rotovated. Suddenly instead of one plant I had a billion, as I then discovered that knotweed regenerates from 0.25" or so of root.

Even after digging up and burning the rootball, it still took me 7 years of roundup applications to kill it off entirely.

Some stuff is tougher than others and it's not clear that just spraying on super-strength is the way to go, rather than following the instructions.

[Grimly Curmudgeon]

What happened with my brambles was an apparent non-occurrence then suddenly, about two months later, with the onset of the colder months, they died off. I presume the sap had withdrawn to the root ball and killed it. Magical, it was. Honestly until that occurred, I was beginning to think they were indestructible.
