Any time you are using a post-emergent herbicide, including ones like Fusilade, the weeds or grasses you are targeting must be in an actively growing state and soil temps need to be above 65 degrees consistently for you to see maximum results. You will also want to make sure you are using a surfactant with this product like the Southern Ag Non Ionic Surfactant.
