Some early winter wheat harvest results in South Dakota have shown some low test weights. One field reported 47 pounds per bushel which is far below the 60 pound bushel that is needed to avoid a price discount at the elevator. SDSU Extension Plant Pathology Field Specialist Bob Fanning says about the only option for very low test weight wheat is to harvest it for hay.
Fanning says if a producer harvests his crop for feed wheat they need to check with their crop insurance agent to see what options they have. They also need to check their herbicide, fungicide and insecticide labels to make sure they’re past the pre harvest interval. He says if a producer is harvesting wheat for grain, steps can be taken to try and increase the weight.
Fanning says this is the latest wheat harvest he’s seen in 25 years. He says several factors can lead to low test weights including drought, diseases, crown and root rots and high infestations of aphids.
