According to K-State Research and Extension, "The wheat crop is moving quickly and is ahead of schedule in many locations. Now is a critical time to assess the need for a foliar fungicide application."
"Stripe rust is most yield-limiting when it advances to the upper canopy, particularly flag leaf. The risk of stripe rust causing yield loss is a function of several things, including:
1. Timing of first local disease detection in relation to crop growth stage (earlier detection can sometimes mean higher risk).
2. Weather conditions: specifically moisture and relative humidity.
3. Variety genetics: varieties with better resistance ratings will generally have lower levels of yield loss than those that are susceptible."
