Wheat disease ratings

Page last updated: Thursday, 3 May 2018 - 2:22pm

When selecting a wheat variety to implement in a farming system, it is important to be aware of the variety's disease package to plan management options. The disease resistance ratings for wheat varieties in Western Australia are available (see Documents). Understand the likelihood of disease occuring in a paddock and don't plant a susceptible crop into a high disease risk paddock.


Severity of disease in wheat crops depends on the presence of inoculum carried over from last season, favourability of seasonal conditions, pathotype virulence and varietal susceptibility. In planning which variety to grow or how to manage the variety that has been chosen, it is important to review the current disease resistance ratings. Being aware of disease risks to a crop allows for appropriate planning and proactive management to reduce risk of yield losses. The attached documents provide the updated ratings.
