An interactive discussion on the current status of herbicide resistance in Iowa and selecting management options for the future.
Herbicide resistance weeds represent one of the most important issues facing agriculture in Iowa. The lack of diversity in weed management has resulted in widespread resistance to glyphosate in common waterhemp, giant ragweed and marestail. The objective of this meeting is to provide information about the causes of herbicide-resistant weed populations, objectively evaluate weed management programs that are commonly recommended in Iowa, and support the design of durable weed management programs for attendees. Individual weed management options will be discussed and assessed for adoption by growers to manage the growing herbicide-resistant weed problem. The program will be interactive and participatory.
CCA continuing education credits have been applied for - 3.0 CEUs in pest management.

Program
| Time | Topic |
|---|---|
| 8:30 am | Registration opens, morning refreshments available At registration attendees will be given a short survey to complete about what weed management programs they are currently using. This information will be compiled for use during the program. All responses will remain anonymous. |
| 9:00 | Understanding herbicide resistance The ecological and biological reasons that herbicide-resistant weeds evolve will be discussed and the implications of current crop production practices on herbicide resistance presented. |
| 9:45 | Break |
| 10:00 | Optimizing the system Current recommendations (both industry and academic) for weed management will be presented and assessed for the potential to select for herbicide-resistant weeds or effectiveness in managing existing herbicide-resistant weed populations. |
| 10:45 | What needs to be done? An open discussion on selecting herbicide programs and weed management strategies that will work on your farm will be the focus of this segment of the program. This will include a look at current programs being used in the area (determined from morning survey) and compare them to what research indicates is required to protect the value of the limited number of herbicides available. |
| 12:00 pm | Lunch (provided) |
