Stripe rust found in Crosby county

I've began to notice stripe rust on winter wheat across Crosby county this week. This is one of the earlier developing wheat rusts due to the fungus preferring moist, cool conditions. We had some rains on the southern high plains, which has eased some of the stress of the 2016 growing season, but at the same time it has made the wheat more susceptible to fungal infections. Stripe rust appears as yellow-orange pustules (shown below) on the plant and will turn dark and shiny as the wheat grows.

If you've planted a susceptible variety make sure to check your fields and consider using a fungicide. Below are useful links for how to scout your wheat, associated yield losses, and fungicides available this spring.
