The war against weeds in the NSW Central West continues and one Charles Sturt University (CSU) researcher is determined to help win the battle. A dominant weed in the region is serrated tussock, one of Australia's most noxious weeds estimated to cost NSW farmers more than $40 million each year in lost production. Dr Aaron Simmons from the University’s School of Agricultural and Wine Sciences will be talking at regional meetings organised by the NSW/ACT Serrated Tussock Working Party about results from research conducted over the past four years by researchers at CSU and the NSW Department of Primary Industries. “The research has been used to improve current guidelines on best management practice for controlling serrated tussock in native pastures,“ Dr Simmons says. “'Serrated tussock has no boundaries - it is not just a 'farmer's' problem, it's an environmental problem that belongs to the whole community.“
