Postemergence herbicides are used to selectively control which types of broadleaf weeds in turfgrasses?

• A. Annual only
• B. Biennial and perennial
• C. Annual, biennial and perennial
• D. Only perennial

Answer: (C)

Postemergence herbicides are used after weeds have emerged and are designed to selectively kill broadleaf species while grasses remain unharmed. Because many broadleaf weeds can appear in turf with varying life cycles, these products are capable of controlling annuals, biennials, and perennials. So, the best choice is that postemergence herbicides can selectively control broadleaf weeds across all life cycles—annual, biennial, and perennial—in turfgrasses.
