## Resource

In this video, I break down the research on biological and oil-based fungicides for dollar spot control in turfgrass. We examine whether products like biological fungicides, mineral oils, and plant-based treatments actually work compared to traditional chemistry. The results show that most biological products failed to provide consistent, season-long dollar spot control, while some oil-based products offered limited suppression under lower disease pressure. If you're interested in dollar spot management, fungicide alternatives, and evidence-based turfgrass science, this video is for you. #turfgrass #dollarspot #fungicide #soilscience #golfcoursemanagement #lawncare #turfgrassscience Become a member of Turfgrass Epistemology and support turfgrass research:www.youtube.com/@TurfgrassEpistemology/join Voicemail:859-444-4234 Apple Podcasthttps://podcasts.apple.com/us/podcast/turfgrass-epistemology/id1717271379 Spotify Podcasthttps://open.spotify.com/show/1cTpdrChToeEFAOX9wkXFI iHeart Radio Podcasthttps://www.iheart.com/podcast/1323-turfgrass-epistemology-129043524/ Podbeanhttps://turfgrassepistemology.podbean.com/ Online consultingCalendly.com/TravisShaddox TwitterTwitter.com/TravisShaddox EmailTravisShaddox@gmail.com Turfgrass Programs and Extension Service Information:https://www.usna.usda.gov/assets/images/as_pdf_image/LandGrantColleges.pdf
