Climate change is likely to increase the number of weeds on Australian farms and undermine traditional methods of killing them, scientists have warned.

Dr Peter Hayman, from the South Australian Research and Development Institute, said rising levels of carbon dioxide and higher temperatures would increase weed problems.

“Farmers face an array of changes cascading from the global climate shift that will require a whole range of adaptive management measures on the ground”. Haymen said.
