With all the recent rainfall, many producers are concerned about the level of weed control that their preemergence and postemergence herbicides will achieve this season. Even with the best management, occasionally something can interfere with a sound weed management or conservation tillage program. Whether it's weed and crop management histories, weather conditions, or what seems like just bad luck, you may feel that you'll have to head to the field with the cultivator this year. More than half of Iowa's producers make that choice every year.
