Summary
In this video, I review the research article “Strategies for Increasing Ferrous Sulfate Efficacy Against Dollar Spot of Creeping Bentgrass.” We examine how ferrous sulfate (FeSO₄) can suppress dollar spot, how application techniques affect performance, and whether combining it with chlorothalonil improves disease control. 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 [email protected] Turfgrass Programs and Extension Service Information:https://www.usna.usda.gov/assets/images/as_pdf_image/LandGrantColleges.pdf
