THE Grains Research & Development Corporation (GRDC) and CSIRO, Australia’s national science agency, are urging growers and advisers to be vigilant due to reports of moderate to high mouse activity in several regions across Australia.

 There is moderate to high mouse activity in parts of the north Adelaide Plains, Victorian Mallee and Wimmera, and pockets of high activity on the Darling Downs in Queensland, and in the Central Eastern Wheatbelt of WA.
