paint and plant ...

it gets sucked into the wood .. and thats it ...

it will not.. in the dark of the night.. then run around the yard and infect other things ... nor ... if the roots touch in the future.. cause any problems ...

you might need a fresh cut on the stump.. to insure you hit the cambian layer ... no need to apply it on the woody center ...

if any new shoots pop up .. snip them and use a drop of RU on them ...

Thanks, I was mostly worried about roots intertwining. The euonymus mostly stays put at night. Although I do have a couple others...

From Chemistry Word magazine, Sept. 15, 2015 issue:

California’s Environmental Protection Agency (Cal/EPA) intends to list the herbicide glyphosate – the active ingredient in Monsanto’s RoundUp – as a carcinogenic chemical under the Proposition 65, which requires the state to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. Theannouncement came on 4 September, following a conclusion by the World Health Organisation’sInternational Agency for Research on Cancer in March that glyphosate is a probable human carcinogen.

Sales of the product are not restricted by the Cal/EPA listing, but adding glysophate to the Prop 65 list would mean that businesses will be required to provide a ‘clear and reasonable’ health warning on Roundup and other glyphosate products. World usage of glyphosate is at an all-time high, with its use increasing more than 20-fold since 1990, according to the Center for Biological Diversity (CBD). The conservation advocacy group says this upsurge is largely due to the widespread adoption of crops, particularly corn and soy, which are genetically engineered to withstand what would otherwise be fatal doses of glyphosate.Recent research also indicates that chronic, low-dose exposure to glyphosate can cause liver and kidney damage, and studies have pointed to glyphosate as a leading cause of the decline in monarch butterflies.

It a Euonymous, not a Cottonwood...don't worry about killing it with RoundUp and just break off the few sprouts that do grow.

I dug one up last fall. It took alot of elbow grease.

Regardless the ultimate status of glyphosate's safety, the cut-stump method involves a tiny amount of active ingredient and a chance of operator exposure down near zero. We need to keep these things in mind when discussing this or any other chemical tool. BTW, I'm certain that the natural world is full of toxins...plants poisoning each other via allelopathic chemicals all over the planet. Must we ban these species of plants because someone could, via truly bizarre methods, manage to poison themselves? No, I didn't think so...
