Rust Fungus Cure? for Himalayan Balsam

Came across this on my travels:

A Rust Fungus that exclusively attacks Himalayan Balsam

http://himalayanbalsam.cabi.org/the-proposed-solution/

and this:

"26 August 2014 – From today, not-for-profit research organization, CABI, will be releasing a rust fungus at locations in Berkshire, Cornwall and Middlesex as part of field trials to control the non-native, invasive weed Himalayan balsam (Impatiens glandulifera) using natural means."

So it wont eradicate Himalayan Balsam, just make it look a right mess?

 

That's interesting Kristen, wonder if they can find one that does Rapeseed too, that's crowded out the Balsam along the Parrett.
