S11E6 - S11 E6 - Crabgrass

In this episode, Joe and Alyssa talk crabgrass with Purdue's Dr. Aaron Patton and PhD candidate Vera Vuković, covering why smooth crabgrass dominates lawns, how mowing height and fertility can dramatically reduce infestations, and what new research reveals about seed dormancy, germination cues, and emergence timing. They break down practical pre‑ and post‑emergence control strategies—including phenology-based timing and herbicide options—while also touching on emerging issues like quinclorac resistance.   https://edustore.purdue.edu/turf-100.html   https://turf.purdue.edu/turfgrass-weeds/   Aaron Patton on X: @PurdueTurfDoc
