If you can't burn 'em, poison 'em

Researchers in Scotland think they've finally come up with an effective way to fight the invasive shrub Rhododendron ponticum, a Eurasian species thought by some to be the most invasive plant in the UK (what about knotweed :-)). As reported by The Scotsman, field tests have shown that injecting herbicide directly into the plant's stem can kill it within six months, at which point the dead growth can be easily removed. This method of managing infested sites is relatively inexpensive, which is sure to make it a popular choice in the years to come. The ISW fisrt posted about R. ponticum back in November 2003.
