Certainty is approved for which type of grasses?

• A. Good control; for use on warm-season grasses only.
• B. Good control; for use on cool-season grasses only.
• C. No control on warm-season grasses.
• D. Used for ornamental grasses only.

Answer: (A)

The key idea is that pesticide labels define exactly which grasses you may treat. Certainty is registered for use on warm-season turfgrasses, and the label notes it provides good control on those grasses. That means it should not be used on cool-season grasses, and it isn’t intended for ornamental grasses either. Using it beyond the approved grass types can lead to poor weed control and possible injury to the turf, and it may even violate label directions. So the best answer reflects both the effectiveness on the eligible warm-season grasses and the restricted use to those grasses.
