Modes of action are a major consideration when designing an effective herbicide program. This is particularly true now in Pennsylvania, as herbicide resistant weeds continue to proliferate throughout the state. One of the biggest causes of herbicide resistance is the use of the same herbicide mode of action repeatedly with little diversification. Alternatively, diversifying herbicide modes of action helps slow the establishment of resistant weeds. Because of this, knowing how to select and interpret mode of action is a precursor to designing effective application programs. This brief, 9-question quiz is a fun and informative way to test your MOA know-how. All answers are completely anonymous. You can see your score and the correct answers after clicking "Submit."

The quiz was written by a team of university extension weed scientists from 14 universities and the USDA Agricultural Research Service, and is being distributed in several states including PA. Find more information on weed management tactics and herbicide resistant weeds.
