Volunteer wheat can provide the summer "green bridge" for the disease wheat streak mosaic and other virus diseases. This almost always occurs as a result of wheat seed shattered from heads during hailstorms.
Research indicates that three inches of water are saved in the soil profile when weeds are controlled in a timely manner after winter wheat harvest and as a result, corn and grain sorghum yields are increased.
Recent observations indicate very high populations of wheat stem sawfly in Nebraska wheat fields, with emergence not only from field edges but also deep within fallow fields. Documentation on infestations is encouraged for successful fall sawfly management.
This year, the Nebraska State Variety Trial team resumed corn hybrid trials. These were planted at four rainfed sites (Saunders, Clay, Perkins, and Cheyenne counties) and two irrigated sites (Clay and Perkins counties).
