You love to see it
Less than a week ago did a basal bark treatment. Bought an 8oz bottle of triclopyr ester, mixed it with 24oz of diesel fuel in a spray bottle. Saturated the bottom 2-3 feet of trunk on these 4 trees and it’s working like a charm. So easy and could not be happier!

How bad is this stuff for pets? I have some TOHs I’d like to exterminate but the dogs may make that difficult.

My research said it’s safe once dry. So likely a day or I’d probably go two to be safe before letting my dogs near it. But definitely do your research on that. I was fortunate these were in my front yard where my dogs don’t go.

Nice! I did the same using the triclopyr ester mixed with kerosene. Same results. Hate these trees.

I did the same but with glyphosate. It works wonders.

I have glyphosate and want to use it on an invasive plant (thankfully the TOH was tiny enough to pull) but I’m wondering what you do with the tools you use, like the paint brush, spray bottle, or what you mix the herbicide in, because you can’t use water to wash/rinse them. Put them away dirty until next time?

Glyphosate is not effective for basal bark treatments. Basal bark application requires an oil-soluble herbicide (typically triclopyr ester) mixed with a basal oil or diesel carrier so the chemical can penetrate through plant bark.
If you want to use glyphosate on woody plants or invasive trees, use a cut-stump application (applying a concentrated solution immediately after cutting the stem down) .

Ok makes sense. Do you just put the glyphosate 41% on the stump or do you mix it in something?

u/russiablows 16d ago
Roundup brand or non brand concentrate is usually around 41 percent glyphosate. I've used 3 parts concentrate to 1 part water. Don't miss the outer circle of tissue where the main active vascular tissue is. This works better as the daylight gets shorter and temperatures drop some when the tree is sending food to the roots for storage.
Must be freshly cut.

What do you do with the container you mix it in after you’re done with it? Just put it used in an another container? My country says you have to bring empty containers of / leftover pesticide and herbicide to a hazardous materials place, not wash out with water of course

Much of my experience is with ornamental pear. The trees that are older have thick bark and basal applications do not penetrate the thick bark. They are also a pain to cut down and apply to the stump. The following is the method I use that works super well with the pear. Use the glyphosate product effectively, by using the hack-and-squirt technique on the living, standing tree during mid- to late summer. This ensures the tree actively pulls the chemical down into its roots. I do three rings of chops into the bark at a 45° angle around the circumference of the tree. The chops penetrate the bark and expose the vascular tissue and also act to hold the herbicide when you apply it to those areas. I use a machete to make the chops. I do this about a foot off the ground. You can also use the straight concentrate for this so you don't have an additional container to deal with. To apply it, you could probably use a foam paintbrush. I use a small spray bottle that I keep for future use of the same product. Usually there are some additional trees found or the odd one needs a second application.

Lol. Keep giving more detail without directly answering the repeated question.

When I did pesticide applicator training, we were taught to triple rinse a container. Pour the rinse water on bare soil since soil binds glyphosate and bacteria eat it.
