fluazifop (Fusilade DX)

Rate 0.25 to 0.375 lb ai/A (1 to 1.5 pints/A)

Time Apply to actively growing bermudagrass with 4- to 8-inch runners.

Remarks Apply with 1% (v/v) crop oil concentrate or 0.25% (v/v) nonionic surfactant. Acts very slowly, taking at least 2 weeks and often 4 weeks to show effectiveness. Do not apply to stressed grasses. If weeds regrow, reapply at 0.1875 to 0.375 lb ai/A.
