Our lawn was sprayed with Sure Power Selective Herbicide mistakenly by a contractor who came to the wrong address. We have established Zoysia approx 40yrs. Areas are yellow on the top and some areas are burnt and others appear dying. Can you offer any suggestions to improve the situation. We have not received any guidance as to what we can do to prevent further damage. We are watering the areas during the day. Please we would appreciate any information.
We are really sorry to hear about this mistake you are dealing with. Yes, many herbicide products that are used on cool-season turfgrass lawns should not be used on zoysia or bermudagrass. Unfortunately, there is not much you can do at this point. We recommend continuing to water as you are doing and hope that will help flush out the products but we cannot guarantee this will help. You will have to wait and see. I am sorry we cannot offer other suggestions.
