With the short timeframe for fieldwork this spring prior to planting, early weed management may fall to the bottom of the priority list for many. For those who have persistent issues with winter annuals (field pennycress, horseweed/marestail) in no-till, an early burndown treatment may be worth the extra effort this spring. Winter annuals resume growth soon after the arrival of warm temperatures, so as soon as fields are fit the weeds will be susceptible to spray.
