Default Alliaria petiolata (Garlic Mustard) is allelopathic

Some of you may have known this already, but I didn't. I've seen this stated a few different places. Even more reason to remove Alliaria petiolata (Garlic Mustard)

Here is the site I'm quoting from:
https://njaes.rutgers.edu/fs1212

"Research shows that garlic mustard is allelopathic, meaning that it releases chemicals which can inhibit the growth of other.plant species."

I'm not sure that I knew this and forgot...or I never knew this.

That said, I guess it doesn't surprise me, but you are right...even more of a reason to eradicate it.

I have to be very thinkful that, in spite of all of the nasties I have dealt with and continue to, I've never seen this species on my property or even in my neighborhood. Whew!!!

I just read through this paper https://bioone.org/journals/the-jour...-15-00059.full which is a review of the Allelopathic effects of garlic mustard. It shows that yes the compounds the plant creates are allelopathic in some controlled experimental studies, but they are more transient in the field, that is the compounds are broken down quickly by other plant enzymes and soil microbes. I think the other features of the plant combine with the allelopathy to make it such a nuisance, like the early and late season growth and the high seed production.

You are fortunate in that respect.

Yes, Jack. You are lucky Jack. So far I just have seen a few here. I hope it stays that way.

Skip, thanks for the link. I must admit I ended up skimming not reading the paper you referenced. I'm not sure I'm convinced it isn't allelopathic but the complaint that studies didn't recreate field conditions sounds reasonable. I definitely like the idea garlic mustard causes harm only with the tools I already knew it had.
