Ryegrass toxicity spreading – Western Australia
THE Department of Agriculture and Food has warned farmers to start checking their livestock and paddocks for signs of annual ryegrass toxicity as the organism which causes the disease is spreading.
DAFWA scientists have warned most areas in the Wheatbelt were now known to contain ARGT organisms and that the Lakes District and surrounding areas north to Hyden could be ‘hot spots’ for ARGT this year.
The disease costs Western Australian farmers an estimated $40 million each year in lost production and livestock deaths, and economist David Kessell said a new map of ARGT affected areas showed the potential for the disease was spreading.
“The organisms that cause the disease are now present from Northampton, throughout the agricultural areas and the coastal plain through to Esperance,” he said.
Mr Kessell said pasture paddocks that were in crop last season were particularly at risk.
“It is important that farmers in at-risk areas look for deformed ryegrass heads and maybe yellow slime,” he said.
