We need more Tinfoil Turfgrass episodes! Keep up the good work!
Really enjoy having this podcast queued up. Dr. Shaddox does a great job of sharing his knowledge (especially with a trained monkey like myself) while still holding my attention.
Travis speaks like a true professor. Dull and monotone. His sentences start off normal and then he eventually ends them mumbling in a low voice. Maybe it’s just me, but if there is any background noise I can’t understand half of what he’s saying. Grab a good pair of isolation headphones. You’ll need them.

This show centers on evidence-based turfgrass science, focusing on practical management for golf course greens, sod production, sports fields, and lawn care. Topics span disease control (dollar spot, red thread, brown patch), nutrient and irrigation strategies, dew and leaf-wetness management, and critical appraisal of marketing claims in the turf industry. A recurring strength is rigorous scrutiny of published studies, with host-led explanations, real-world anecdotes, and a willingness to challenge sales-heavy messaging. The format tends to appeal to turf managers, extension-minded professionals, and informed homeowners who value data-driven decisions and transparent discussion of methodology and limitations.
