Is this safe for ryegrass lawns?

The listing states that this product is intended for ryegrass lawns. But then lists that both annual and perennial ryegrass are targeted pests. If this kills ryegrass, this is a very risky listing and I'd be quite upset if I bought it and it killed my ryegrass lawn.

Answer:

The product label states that The Andersons 21-0-10 Fertilizer with 0.25% Dimension Turf Herbicide will control annual and perennial ryegrass at the "Program 3" rates and will suppress at the "Program 2" rates. The label also states, "This product should only be applied to lawns and ornamental turfs that are composed of the following turfgrass species that have been determined to be tolerant to applications of this product. When applied as directed under the conditions described, the following established turfgrasses are tolerant to this product:" and it lists it can be used on perennial ryegrass (not annual). "Program 1" rates can be used on perennial ryegrass as long as you are following the instructions on the product label.
