Avoid planting winter wheat next to late maturing green corn fields or late maturing oat fields. Much of the control for wheat streak mosaic hinges on successful control of volunteer winter wheat and weeds in stubble fields and other areas. These are big users of soil moisture and nutrients. If soil moisture is available, they may use as much as three inches of soil water after harvest. Moisture conservation and weed seed production especially are important if one is considering planting a crop in that field the next spring.
Several options are available.
Most years sweep blades can be used immediately after harvest. The weather must be dry and hot to successfully use a sweep blade, as weeds must wilt within 30 minutes for good control. Usually, if you do not blade immediately after harvest, it is impossible to get the blade into the ground later unless moisture is received. Two bladings usually are necessary in the fall for good weed control, since the first usually plants weeds seeds. Another option is to use herbicides.
