If it is, it must be pretty mild. It's an invasive in my area, but seems to grow in thickets with a diversity of other trees: sumac, sweetgum, oaks, persimmon, etc. That could indicate that its allelopathic effects are on short rooted plants, and it has little effect on plants with tap roots. I only got 152 hits with the terms 'chinaberry' and 'allelopathy' on Google Scholar, so it doesn't look like it's been studied much.
