Re-applications and timing will depend specifically on what program you choose to use. Please review page 4 of the product label to determine the program that will best suit your needs. For example, if Program 1 is done (which is the most recommended for residential lawns), it will provide 3-5 months of pre-emergent control. Most pre-emergent products will have to be applied at least twice a year to prevent Spring and Summer weeds. Be sure that you do not exceed the maximum annual rates for your specific type of turfgrass.
