A combination of low glyphosate prices deterring preemergence applications and a wet June preventing timely postemergence applications has resulted in weeds reaching levels capable of interfering with crop growth and yield potential in fields across the state. While many fields will still be able to be ‘cleaned up’ when they dry, the lost yield cannot be recovered.
