However, you should seed your lawn ASAP to avoid bare spots where smooth crabgrass dies. The only way to seed the lawn before the end of September (optimal seeding time) is to hand pull the crabgrass or apply quinclorac (Drive™). Drive is the only chemical that can be applied 10 days prior to Kentucky Bluegrass seeding and will control smooth crabgrass. Use a methylated seed oil adjuvant with Drive. Apply Drive, wait 10 days, aggressively work the soil with a verticut unit or a garden rake, and seed KY bluegrass. Keep the area watered until the seedlings emerge (about 3 weeks). Use a spring crabgrass control in April to prevent crabgrass from infesting the lawn next year.
