Why Control of Volunteer Wheat is Critical to Protecting 2018 Yields

Timely control of volunteer wheat and other weeds is key to managing yield loss risk in your 2018 crop. Yield-limiting risk factors affected by weed control include wheat streak mosaic and other diseases, insects (wheat stem sawfly and disease vectors), moisture loss, and increased weed seed production.
