WOYM – Let’s Go Viral, Kelsey Andersen Onofre
In this episode, Aaron Harries speaks with Dr. Kelsey Andersen Onofre, an Assistant Professor at Kansas State University specializing in plant pathology and the impact of diseases on wheat crops.
We discuss the significant disease pressures affecting the Kansas wheat crop in 2024, emphasizing the challenges posed by stripe rust, leaf rust, and stem rust, along with the emerging threats of viral diseases.
Stripe rust emerged as the most destructive disease, with early detection in April and increased severity in May.
Effective management strategies include genetic resistance, timely fungicide applications, and controlling volunteer wheat.
Diseases like stripe rust and stem rust can lead to severe yield losses, historically reaching up to 25% due to common bunt.
Viral diseases, particularly wheat streak mosaic virus and triticum mosaic virus, are becoming more prevalent in central Kansas.
Producers should utilize resources like the Kansas wheat variety guide to make informed decisions on disease management.
Controlling volunteer wheat within two weeks of planting is crucial to prevent wheat streak mosaic.
