As promised last week heres a few before and afters of a small area of mares tail that I sprayed off with a 4:1 solution of Agritox 50. I had to walk about 500m down my road due to getting a bit carid away with the knapsack last year and destroying all roadside weeds about the house Lol.
Before at approx 6.30pm yesterday
After at approx 7.30 this morning 13hrs. You can see it's already taken quite a knock and is starting to wilt heavily as are the nettles.
I'll keep taking photos over the next few weeks but I'm fairly confident that the test patch will be totally eradicated and fully wilted by monday.
Would applying agritox in late summer be more effective? With knotweed it is best to apply at this time, when the plant is getting ready to go dormant for the winter - drawing down energy from the top growth and into the crown, where you want the glyphosate to go.
yes it is more effective in late summer it definately works quicker and the chance of needing a second application is slim. Glyphos has very limited effect on mares tail other than scorching it to ground level and if you don't kill it first time it develops a resistance to it.
Cheers Pablo.
On the subject of legislation; can you still buy 20ltr tubs of concentrated weedkiller, such as roseate or roundup, or do you need documentation these days?

I'm not aware of whether it is or not but it goes through the knapsack just fine and I wear a full suit and mask when I use it. It does start to turn into a mouldy solid after about 48hrs of being mixed with water so you have to be careful how much you make up and the sprayer needs rinsed straight afterwards. Al yes you need to be certified to use any commercial grade chemicals although the enforcement is pretty much non existant meaning it's pretty easy for anyone to walk into a suppiers and buy some pretty potent stuff. I usually buy chemicals in 5-10ltr containers it's easier to pour and measure and store that way. Also they all have a use before date and I wouldn't use them often enough to get through 25ltrs before it was up.
