hey manny ...

cut any branch.. or root.. and you will see a thin green line right under the bark .. that is the cambian layer .. that is the vascular system of the tree .. and that is the ONLY place a killer will work ...

drilling into the wood is just a waste of chemicals ...

stump killer or roundup .. 100% from the 41% solution for round up .. dripped on the cambian.. will EVENTUALLY kill the root system ...

just snip off a sucker as they are called.. and drip some killer on it .. and do it every time you see a new one ... and in a year or two.. the root system will die and start rotting away ...

dont you wish you would have never planted that thing??

ps: at the link.. you will find a very precise applicator for single drips .... please do not harm mother earth with excessive application .... nor explosive incendiaries ... lol ...

pps: tnt might work.. but the neighbors will probably be really p.o.'d ...

Here is a link that might be useful: link

LOL I love the applicator link!

Either triclopyr (Brush-B-Gon, Garlon, etc) or glyphosate (RoundUp, Gly-4, etc) can do the job well. As Ken said, use them in their concentrated form and apply them to the freshly cut phloem (technically, not the cambium, but unimportant unless you are studying how it works). It's also important to treat all the suckers (not just a few or a few now and a few some other day).

use them in their concentrated form and apply them to the freshly cut phloem

==>>> yeah.. get this.. its actually in the instructions.. lol .. its a labeled use ... go figure on that ...

garlon is not available to the home owner ... regardless.. its the active ingredient that is important ...

ken

ps: at least he didnt argue that it applied to the vascular system.. lol.. or is that next ....

Nope, that's what I was actually suggesting!

BTW, homeowners shouldn't have much problem finding Garlon. Farm supply stores and similar places should have it. A license is not required to apply it on your own residential property (at least in most places).

Thank you all guys for responding to this thread. I will try the chemical application as described by Ken.

way back.. 10 years ago.. i was told garlon was restricted [in MI at least] ... but after reading the roundup brochure .. i didnt need it ..

good luck manny ... took me 3 years to kill a poison ivy vine .... its more about followup and constantly doing it.. rather than hard work ...

please do secure the mis-labeled applicator.. or better yet.. since you arent diluting it.. put it back in its properly labeled container after every use ...
