However, I want to point out that efficacy is a side issue unrelated to my concerns about the communication from the VBA. The communication was a call for action from the membership based on very little information outside of the assumption that this intervention would eliminate Japanese knotweed from Vermont and that this would reduce the nectar flow at a time when nectar would be particularly useful. The UK study suggests that the this particular control agent is not likely to be able to eliminate knotweed, so I would propose that the concern raised in the VBA communication is unwarranted (especially as it was having trouble overwintering in the
UK). The UK studies also suggest that this agent is very specific to knotweed. But I again digress a bit, as I do not want to necessarily advocate one way or another, my objection was that the communication itself was very one sided and totally failed to actually educate the membership on the issue. Literally 30 seconds of "Googling" got me those links. One might find points to find fault or concerns in them, sure. But the VBA communication made no effort to even do that, it was little more than the opinion of whoever wrote it and served as dog whistle to the VBA membership without any attempt to actually inform the membership. That is what I objected to.
