Stripe rust on wheat flag leaf

We’re midway through spring, and stripe rust is spreading to wheat fields across the U.S. Earlier in the year, the cool weather caused rapid development of stripe rust in Louisiana and spores were forecasted to move north. Since then, Kansas State University has reported stripe rust in a few counties in the state and cautioned that cases are expected to increase soon.

With the potential to cause yield losses of up to 40%, your bottom line can take a significant hit from stripe rust if you’re unprepared.

To help you take action against stripe rust and prevent yield loss in your fields, consider these tips:

• Plan ahead with a resistant variety. Each season, plan to plant a variety resistant to stripe rust to protect wheat fields from infection and help build your comprehensive crop protection program.
• Monitor your area’s weather. Stripe rust development occurs when the weather is moist and cool (50-60˚F). Under these favorable conditions, rust infection can occur within 6-8 hours, so keeping tabs on the weather is crucial.
• Start scouting early. Scout your fields early for yellow flecks on wheat leaves. Symptoms later appear as yellow or orange pustules in a striped pattern.
• Apply a preventive fungicide. If a susceptible variety is planted or if fields have a history of stripe rust, consider a preventive fungicide application. Feekes growth stage 8 is the optimal application time to manage this disease.

To protect your yield potential against stripe rust and other key flag leaf diseases, we recommend an application of Trivapro® fungicide. Delivering longer-lasting residual control, Trivapro helps prevent diseases from starting and shuts down existing infections. Plus, it delivers consistent plant-health benefits to help you maximize yield potential.
