Not that I want the government in my womb but it is a shame when something is declared invasive soo many nurseries including the Lowes and Home Depot keep selling them.

Is it legal to sell Kudzu even?

do you think that wound was deep enough to expose the cambian ??? .. so that any killer might actually work???

The federal government seems to consider it mostly a state issue, I know several states do not permit their sale. The best course of action is to write to your local state reps and try to get a state law enacted.

Looks like a hack-and-squirt treatment.

"hack and squirt" is right. Infinitely better than trying to spray the foliage, especially with a large tree. This kind of basal herbicide application is used for Chinese Tallow, Chinaberry, TOH and numerous others. Am going to observe this tree next year, surely it will not resprout from the base.

Massachusetts is one of the most proactive states for prohibiting the sale of invasive plants, but Pyrus calleryana is on the prohibited plant list (yet). I have noticed that that in one particular part of town, the callery pears are starting to naturalize in wild areas. It's probably only a matter of time, these pears are planted everywhere (they are pretty in the Spring).

In the meantime, I have my hands full with plenty of invasives, particularly oriental bittersweet. It seems to be spreading at an alarming rate. I keep hacking away at them, but it's a losing battle when most homeowners let their yards grow out of control.
