Wheat disease ratings

Please note: This content may be out of date and is currently under review.

The 2017 disease ratings for wheat varieties in Western Australia are available (see Documents). Updated disease ratings for recently released varieties such as Bremer, Chief CL plus, Cutlass, Hydra, Impress CL Plus, Ninja, Scepter, Tungsten and Zen are available. Growers can also access the disease ratings for the commonly grown varieties. These include Mace, Calingiri, Corack, Magenta and Yitpi.


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.

It is important to note that after the discovery of the new pathotypes for leaf rust in Western Australia in 2013 and 2015, some wheat varieties have had their leaf rust resistance ratings altered. The attached documents provide the updated ratings.
