Whole lawn has lot of bentgrass I think. If I replace with new sod. Do you recommend using tenacity on the dirt before rolling out new sod.
If you are doing a full lawn renovation and wanting to kill existing plants before sodding, then we would recommend using a non-selective herbicide to clear the area before planting. You could use a product like RoundUp QuikPro for this application. Then after any existing plants have died and the lawn is prepared, you could put down your sod. We would suggest applying Tenacity after the sod is down as a pre-emergent (or post-emergent as needed) as long as the turf is one that is listed as tolerable on the product label. Keep in mind that the best time to use Tenacity for bentgrass will be in late Summer/early Fall.
