Perennial grass weeds are the most difficult to control. True or False?

• A. True
• B. False
• C. Not specified
• D. Depends

Answer: (A)

Perennial grass weeds persist by vegetative growth and underground storage organs, so they survive and regrow even after cutting, mowing, or partial herbicide damage. Their rhizomes, stolons, or crowns can re-sprout new shoots long after the visible weeds seem to be gone, and their deep root systems allow them to endure stresses that kill or weaken annual weeds. Because of this, a single treatment often isn’t enough; control usually requires multiple, systemic herbicide applications timed to move through the plant’s tissues, along with cultural practices that weaken the weed and strengthen the desired turf. In contrast, annual grasses complete their life cycle in one year and are generally easier to eradicate with timely, targeted treatments, which is why the statement is true.
