Fusilade II is used for suppression of which turfgrass species in tall fescue or zoysiagrass lawns?

• A. It provides bermudagrass suppression in tall fescue or zoysiagrass.
• B. It suppresses centipedegrass in bermudagrass.
• C. It suppresses bermudagrass and may require repeat applications, with potential temporary discoloration.
• D. It is a postemergent herbicide for annual grasses only.

Answer: (A)

Fusilade II is a grass-selective herbicide used to suppress bermudagrass in cool-season lawns such as tall fescue and zoysiagrass. It works by targeting grassy weeds (an ACCase-inhibitor), causing bermudagrass growth to slow and die back while the cool-season turf tolerates the treatment when applied correctly. That’s why the best choice focuses on bermudagrass suppression in those specific lawn types. Temporary discoloration or the need for follow-up applications can occur with bermudagrass control, but the primary target in this context is bermudagrass, not centipedegrass or annual grasses only.
