Am I correct?

Hi

I'm afraid you are not. Indeed both Japweed and Russian Vine have been classified as Polygonum species in the past (Polygonum cuspidatum and Polygonum baldschuanicum respectively).

This means that indeed the introduction of a natural predator has potential dangers even if it only to the commercial growers of Rhubarb.

All the best
