    Q
    Can I apply Ronstar G for lawn bowling greens in Southern California?
    Our Greens are Tiff-Bermuda 328. Mowed at 1/8th inch. We have poa and pearlwort. Is this product going to work to kill this weed? Also, is it safe for our grass. Long Beach Lawn Bowling Club
    A

    According to the label for Ronstar G, this product is not permitted for use on poa annua in California. This product is also not for use on residential lawns.
