Surflan is labeled for use on which grasses?

• A. Tall fescue and warm-season grasses only
• B. Fine fescue and bentgrass
• C. Bermudagrass and centipedegrass
• D. All cool-season grasses

Answer: (A)

Surflan works only on the turfgrasses that the label says it can safely be used on, because different grasses tolerate the chemical in different ways. The label specifies that Surflan is safe on tall fescue and warm-season grasses, so those are the grasses you can treat with confidence when following the label directions. Other cool-season grasses, like fine fescue and bentgrass, are not listed as labeled uses, typically due to a higher risk of turf injury or inconsistent results. It isn’t described as safe for all cool-season grasses either, since tolerance varies widely across species. The takeaway is to base your choice of herbicide on the label’s listed turf species—use Surflan only on tall fescue and the warm-season grasses it approves; for other grasses, pick a product that the label covers.
