Updated Wheat Fungicide Table
With wheat growth and development ahead of normal in 2012, it is important to pay attention to the growth stage when determining if there is a need for the use of foliar fungicides. Active scouting is important to determine which diseases are present and either the incidence and/or severity of each disease relative to wheat growth stage. To help in understanding the efficacy of different fungicide active ingredients, the NCERA-184 (Management of Small Grain Diseases) committee reviews and updates the Fungicide Efficacy Table for Control of Wheat Diseases each year. Ratings for different active ingredients are provided and range from poor to excellent for the following wheat diseases: powdery mildew, Septoria leaf blotch, Stagonospora leaf/glume blotch, tan spot, stripe rust, leaf rust, stem rust, and head scab. These ratings are based on results and observations from trials conducted across different locations (i.e., states) and years and is meant only as a guide. It is important to read and follow the label carefully regarding application timing and recommended rates against different diseases.
