The study found that nozzle selection and application strategy influence performance, and that ferrous sulfate can reduce the amount of chlorothalonil needed and extend its effectiveness against dollar spot. If you manage creeping bentgrass greens or fairways, this research provides valuable insights into dollar spot management, iron applications, and fungicide optimization. #turfgrass #dollarspot #golfcoursemanagement #turfgrassscience #bentgrass #fungicides #soilscienceBecome 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","meta_description":"In this video, I review the research article “Strategies for Increasing Ferrous Sulfate Efficacy Against Dollar Spot of Creeping Bentgrass.” We examine ho…","key_points":[],"chapters":[],"topics":[],"duration_seconds":4099,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/turfgrass-epistemology-6708747/episodes/s4-e15-do-spray-nozzles-and-volume-influence-dollar-spot/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/turfgrass-epistemology-6708747/s4-e15-do-spray-nozzles-and-volume-influence-dollar-spot.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
