Description

Weed management in 2009 was, as usual, a mixed vision of apparent successes and obvious failures. In general, less than complete planning left many producers in dire straits for weed management options after planting. Wet conditions precluded many planned programs and thus once again, untold yield potential was lost due to weed interference. While the postemergence (POST) herbicide applications were generally successful (in killing weeds), it is clear that Iowa fields are becoming more populated by weeds that do not respond to the “programs of choice”. Furthermore, the widespread lack of using an herbicide strategy that includes a residual herbicide resulted in high weed population densities later in the growing season. This does not portend well for the 2010 growing season.
