2 credits: 1A, 03, PA
Annual bluegrass has historically been an important weed of many, if not most, commodity and specialty crops. The extensive reliance upon herbicides as the primary means of control has led to an almost overwhelming presence of herbicide resistance. This course will discuss the currently reported cases of annual bluegrass resistance to various herbicides and how to develop an effective herbicide program.

Annual Bluegrass Resistance Management


Course Description

Annual bluegrass has historically been an important weed of many, if not most, commodity and specialty crops. The extensive reliance upon herbicides as the primary means of control has led to an almost overwhelming presence of herbicide resistance. There are very few commonly utilized herbicides that annual bluegrass has not evolved resistance to – albeit often in isolated or unique populations. However, the worrying trend is that for some turf scenarios, we no longer have effective chemical means of controlling annual bluegrass. This course will discuss the currently reported cases of annual bluegrass resistance to various herbicides and how to develop an effective herbicide program.

After completing this course participants will be able to:

  • Discuss herbicide resistance best management practices
  • Distinguish between the different classes of herbicides and their different sites of action
  • Describe how herbicide resistance is developed and how it can be avoided
