The Register-Guard has this story about Oregon's testing of an innovative new weed-killing system. Called "Waipuna," the system takes a concoction made up of hot water and a corn/coconut sugar extract, and sprays it on plants as a hot foam. The foam insulates its weedy victims in a 200+ degree F blanket, shocking the plant's cells and usually killing it within four hours. The Bureau of Land Management is testing the Waipuna system on several different invasive plants, both herbs and vines.
