Small grain harvest is progressing across Minnesota, with early reports showing strong yields and good grain quality in many southern areas. However, some oat growers are facing challenges with green stems, even when grain moisture levels are suitable for harvest.
Spring wheat producers in the Red River Valley are also being encouraged to scout fields for Fusarium Head Blight (FHB). Fields planted with susceptible varieties, especially those following corn, should be checked first because they face a higher risk of infection.
Growers should assess whether FHB symptoms are present in more than 1% of spikelets. If infection levels are significant, inspecting kernels for damage can help determine the best harvest and grain management strategy.
Lightweight, shriveled kernels can often be removed by increasing combine airflow during harvest. This may reduce grain losses and lower DON toxin levels, helping farmers avoid quality discounts.
When infected kernels are near normal size, removal during harvest is less practical. In those cases, storing grain separately, testing for DON levels, and using methods such as blending, grain vacuums, or gravity tables may help improve grain quality and marketability.
