Wheat Disease Publications and Updates

Two NDSU wheat Extension publications on bacterial leaf streak and rust diseases were updated this winter and are now available for download.

Two NDSU wheat Extension publications on bacterial leaf streak and rust diseases were updated this winter and are now available for download. Both of the publications have updated information on tools that can be used to manage these diseases.

Bacterial leaf streak is becoming more prevalent in North Dakota and was found in 27% of the hard red spring wheat fields scouted between flag leaf and early flowering in 2020. Results from 2020 field research funded by the North Dakota Wheat Commission indicated that that yield loss can vary with bacterial leaf streak ranging from 9% to over 30%. Prevalence of leaf rust and stripe rust can be sporadic because both diseases are dependent on southerly winds (and rainstorms) to carry spores into the state. Currently, there are widespread rust reports of stripe rust in Kansas and as far north as east central Nebraska. It is possible that we may see an early arrival of stripe rust in North Dakota this year, and it will be important to monitor stripe rust reports in the coming weeks, especially from South Dakota.
