Yes, Drexel Diuron 80 Herbicide would injure the myoporum ground covers and ornamental shrubs. Per the product label, “do not use on home plantings of trees, shrubs or herbaceous plants, nor on lawns, walks, driveways, tennis courts or similar areas” Ronstar Herbicide will control weeds in myoporum ground cover and other ornamentals, however, is for commercial applicators only. It cannot be used on residential lawns. We would suggest reaching out to the local nursery in your area or contacting the Master Gardener with the County Extension office.
