Most pre-emergent applications can be applied in early fall and spring. Please click on the link below for the contact information for your local county extension office for specific times for application. I have also included the number to the manufacturer of Hi-Yield Weed and Grass Stopper for more information on applying this product to your turfgrass. Some types of St. Augustine can be very sensitive to products. http://www.csrees.usda.gov/Extension/index.html VPG-888-583-5296
