With mouse populations at high to moderate levels for this time of the year in some cropping regions of Victoria and South Australia, local grain growers are being urged to remain vigilant and take measures to eliminate food sources over the warmer months.
Recent strong winds some parts of the southern cropping region have knocked grain to the ground and combined with any grain spilt at harvest will provide a ready food source to maintain mouse populations through summer, posing the risk of an outbreak in autumn next year.
The latest reports from the Grains Research and Development Corporation’s regular mouse monitoring program indicate that populations in the Mallee are high and damage to crops continues, however baiting appears to be effective. Riverland growers are reminded that baiting must not occur within two weeks of harvest, due to the withholding period.
