Wheat is currently near flowering or recently past flowering across the state. Thankfully, scab risk has dropped statewide due to recent dry weather. Current weather forecasts indicate little or no significant chance of rain in the coming week. Therefore, small grain crops that are heading and flowering in the next 2 weeks should remain at low risk of head scab, and will not need a fungicide targeted at this disease.
