Frost damage to Canola is a significant annual issue for the nation’s grains industry. Spring frosts in particular are the most economically damaging for growers as crop yields and quality are developing at this time.

In this podcast NSW DPI crop physiologist and frost researcher Dr Rajneet Uppal discusses when and where to search within a canola crop for frost damage, how to identify pod damage and recommendation for minimising frost risk generally.

Dr Uppal’s work is being conducted as part of the NSW DPI and GRDC Grains Agronomy and Pathology Partnership (GAPP). Her work is pioneering infield testing methodologies to help better understand the impacts; single and multiple frost events occurring at different growth stages in canola have on grain production.
