Oil as a sub to trichlpyr

[metalman1]

People,

I heard that instead of trichlpyr/kerosene (or ethanol) one can use a dab of motor oil. Example- strip a section of bark at bottom of s bamboo stem, say, 2" high, and all around exposing cambium. Then brush on some used/old motor oil. Know if this really works like trichlopyr?

Thanks, people.

Works on everything but sumac.  That stuff is a survivor, always comes back. 

 Dirtier the oil the better. Gas atf hyd brake fluid etc.

Wow, good to know (and to have it verified). Why would someone pay $$ for trichlopyr??

But why Sumac? It is a plant, and plants eventually run out of starch if they do not photosynthesize. Eventually, that sumac gotta die (right?).

No clue.. Im just a man with hammer.   I couldnt kill sumac with waste oil hack n squirt.

Thanks, Mike. I will try the oil trick on the huge bamboo. They say (like sunac) they are hard to kill. But they cant live forever.

Sumac!! We had someone cut the fields for about 3 years. They never took the back swath, next to the stone walls and every year they was about 6 feet away from the wall. Bushes came in quick and hard. I bought my Father a riding lawn mower to mow around the fields. Best invention ever he said!!!  ;D  The oak and the maple died within a few years. Dad use to say, We grow them to death. But those sumac took years to die, and I do mean years. They kept coming back and this was mowing them every few weeks too. All the other bushes died.
