Wheat Issues – Stripe Rust Alert
Over the last week, stripe rust has been reported in several counties across North Carolina. A stripe rust epidemic can develop much quicker than a leaf rust epidemic. If scouting reveals stripe rust in your field, a fungicide should be applied as soon as possible to preserve yield. Wheat varieties rated susceptible (S) and moderately susceptible (MS) should be scouted immediately. Resistant (R) or moderately resistant (MR) varieties are at low risk. Consult the Variety Characteristics Sheet to determine Stripe Rust susceptibility for common varieties. Apply fungicides to fields containing multiple stripe rust foci first before moving on to fields with less noticeable infections.
ALTHOUGH, I DID NOT FIND STRIPE RUST, we most likely have it. With that said, you should consider treating your wheat for stripe rust if your variety is rated S or MS and you have good yield potential. Products that control stripe rust controls leaf rust. Powdery Mildew was fading with hotter temperatures slowing this disease. However, for the next 2 weeks, temperatures are forecasted to be below normal with normal rainfall.
