Lantana bushes may greatly contribute to your field of bushfires.
I think i may need more attention.
Looks I am loosing a battle, Green stock is increasing exponentially reagardgess of my effort. Even If I have time to spray each clump, there are millions of them everywhere.Then only 1 in 100 is likely to die after soaking in my herbicides.There is also lack of machinery to deal with Lantana in AUstralia.
