If it is necessary to reseed large areas, work the section of the field to be reseeded in a rectangular shape. The area then can be seeded and harvested separately. This will avoid spring and winter wheat mixtures, which will be discounted at the market. Calibrate drills to plant 20 live seed per square foot. Rapid planting of a new wheat crop after tilling an existing stand will greatly increase the chances of wheat streak mosaic moving to the emerging wheat.
Losses generally are most severe when wheat is infected just after emerging.
High speeding in the late season is a natural tendancy. However, as seedbeds dry, equipment performs differently usually through loss of seeding depth control. Higher speed increases this problem especially with spring loaded double disc drills. These units have a tendency to both bounce and seed shallow across hard spots at higher operating speeds. Packer wheel load settings need attention as soils dry and clods harden.
