Does scotts turf-guard fertilizer with crabgrass killer kill Bermuda grass?

There is nothing in Scotts Turf Builder with Halts Crabgrass Preventer that will harm Bermuda Grass. You will want to wait to apply the product though until the lawn is out of winter dormancy. If you apply the Scotts Turf Builder with Halts Crabgrass Preventer before the lawn is out of winter dormancy then it could cause some damage to the grass. If your lawn is still dormant, but you want to apply crabgrass preventer now, Scotts does sell Halts without the fertilizer in it.
