A Yield Loss to Disease Model is being developed that will assist grain growers and consultants to select the best wheat variety and management strategies to optimise yield potential and profitability.

Cereal diseases have a significant impact on production, with wheat diseases – alone – costing the Australian wheat industry $468 million annually in lost yield and control costs.

The new, national tool draws on five years of Australian field trial data and statistical analysis, used to determine likely yield responses to various disease resistance and tolerance ratings for wheat varieties.

A prototype for wheat was unveiled at the 2020 GRDC Grains Research Updates in Perth for interested parties to test and provide feedback so the new tool can be refined and expanded to barley before an official release next year.
