- Summary
- An effective method was sought to control pampas grass (Cortaderia selloana) in conservation sites with difficult terrain. At one such site, the dunes and dune slack communities on Pouto Peninsula, we tested three methods of applying the herbicide haloxyfop from a helicopter: beer keg, weighted nozzle and lance. All three methods gave a similar, high level of control of pampas grass but differed considerably in cost. One year after herbicide application, many of the pampas grass plants in the plots had new shoots, and native plant species had begun to colonise the old pampas clumps. All sprayed plots needed treatment of the regrowth to completely control the pampas grass.
