Which product controls a variety of broadleaf weeds as well as wild garlic and wild onion and is labeled for bermudagrass and zoysiagrass only?

• A. Imazaquin
• B. Confront
• C. Escalade II
• D. Monument

Answer: (A)

Selective turf herbicides are judged by two things: what weeds they kill (the weed spectrum) and which grasses they are approved to be used on (the turf labels). The best choice here is Imazaquin because it is labeled for bermudagrass and zoysiagrass and has documented effectiveness against a broad range of broadleaf weeds as well as wild garlic and wild onion. That combination matches the requirement of controlling those weeds while being restricted to those two warm-season grasses. The other products either don’t offer control of wild garlic and wild onion, or they aren’t limited to bermudagrass and zoysiagrass on their labels, so they wouldn’t meet both parts of the given criteria.
