Yuzu Essence as Weed Killer?

While looking up information about yuzu, I came across this scientific paper from the Fourth Congress on Allelopathy. It's crammed full of scientific jargon, as you would expect, but the gist of it is that it's possible that essence of yuzu might be useful as a weed killer. The idea to investigate uses for yuzu waste came about because the large yuzu industry on Shikoku is starting to experience some environmental problems due to the concentration of waste products from yuzu production. The experimenters discovered that essences derived from yuzu peel waste could inhibit production of roots in cress, crabgrass, alfalfa, lettuce, and ryegrass. Of course, I'm waiting to see what the results on field bindweed are!
