Which list includes other weeds found in Iowa's turfgrass settings?

The correct answer identifies a list of weeds that are commonly found in Iowa's turfgrass settings. Algae, Silvery Thread Moss, and Wild Garlic are all notable for their prevalence in such environments.

Algae can thrive in moist turfgrass situations, often leading to unsightly patches and potentially affecting the health of the grass. Silvery Thread Moss, though not a conventional weed, can invade turfgrasses, particularly in shaded and moist areas, compounding maintenance issues for turf managers. Wild Garlic, characterized by its distinctive smell and ability to spread efficiently, poses challenges in turf management due to its persistence and competition with grass species.

In contrast, the other choices contain either non-typical species for turfgrass, or species that are not as prevalent or problematic as the correct answer indicates. Understanding the specific types of weeds that affect turfgrass settings helps in implementing effective management strategies to maintain healthy turf.
