There is a new, terrible emergent weed species dyschoriste nagchana (common name in Australia is snake herb), that takes over and smothers disturbed or grassed areas in particular. It chokes out virtually all competitors and spreads rapidly.
Managing or eliminating it at this stage appears really difficult unless you catch it very early and meticulously pick it out by hand, bag, and remove it.
The first action by most people has been mechanical, mowing or brush cutting, PLEASE DON’T, IT DOESN’T WORK, every cut fragment can become a new plant.
The main vector for spreading appears, at the moment, to be mowing and gardening contractors who have seeds or fragments attached to equipment.
A good understanding of how to manage, treat, or eliminate it is very limited at present, even in Brisbane, where it has spread from. Early identification is the key, if you get to it quickly, you will save yourself serious costs and heartache. Good luck everybody.
