Just a quick update on what is happening in the WI wheat world today. The Soybean and Small Grain Research Crew was at Chilton today after digging soybean roots at Arlington this morning. Yes soybean does comes first…. At Chilton, powdery mildew was evident in the lower crop canopy, but had yet to move up the stem.
Most varieties have wheat heads emerging from the sheath. A couple early wheat varieties had a few heads starting to flower. However the majority of flowering at our Chilton site should take place late this week into the weekend.
The southern 1/3 of the state has or is experiencing wheat flowering now (Damon Smith applied the FHB fungicides today at Arlington). Below please see a risk map regarding today’s risk for FHB. West central WI is located in the medium to high risk zone so please scout accordingly. Remember risk is associated with weather conditions and crop growth stage. Fungicide options for FHB are found at Management of Small Grain Diseases Fungicide Efficacy for Control of Wheat Diseases.
