Frost is a costly and often unpredictable problem that costs Australian grain growers more than $300 million a year, but the GRDC’s National Frost Initiative is proactively working to develop more frost resistant varieties, identify best frost management practices and to create tools to predict frosts.It’s important to recognise the psychological and financial cost of frost and how devastating it can be, particularly towards the end of the season when producers anticipate harvest only to have it damaged by frost.
