Broadcast treatments would be recommended if you are needing to actually treat the entire lawn for pre-emergence, if you are only needing to treat small areas or use as a post emergent then you can spot treat. Consult your local Cooperative Extension Service for more specific applications timings for your local area. Their contact information can be found by clicking the link below. https://ahsgardening.org/gardening-resources/master-gardeners/
