Killing weeds-mostly dichonda . I have standard & palmetto St Augustine grass. I do not want to harm my trees. I need products that are inactive in soil.
Southern Ag Atrazine Weed Killer for St. Augustine Grass can safely be applied to St. Augustine lawns for targeting listed weeds. It should not be applied to trees or over the rooting area of the trees. We are not aware of a product for selective control that is inactive in the soil. Please let us know if you need further assistance. We are happy to help!
