XL (benefin + oryzalin) is for use on which grasses?

• A. Tall fescue and warm-season grasses only
• B. Fine fescue and fescue blends
• C. Bentgrass and creeping bentgrass
• D. All turfgrasses

Answer: (A)

XL is designed for use on tall fescue and warm-season grasses because those grasses tolerate the benefin plus oryzalin combination at the labeled rates and timing. The active ingredients act as a preemergent herbicide, and the label limits use to grasses that have proven tolerance, which excludes fine fescue and fescue blends as well as bentgrass. Bentgrasses are notably sensitive to oryzalin and can suffer injury, so they aren’t included on the label either. Since the label does not authorize application on those grasses, the only grasses listed as safe and effective are tall fescue and warm-season types. Always follow the label to prevent turf damage and ensure proper weed control.
