S4 E29 Can Silicon Reduce Turfgrass Disease?

S4 E30 Does Manganese Influence Take-All Disease?

In this video, I break down the classic study “Optimizing Manganese Fertilization for the Suppression of Take-All Patch Disease on Creeping Bentgrass.” We examine whether manganese applications can suppress take-all patch, how application timing influences disease control, and why soil chemistry matters. The results showed that manganese fertilization significantly reduced take-all patch severity, especially when soil manganese availability was low. If you're interested in take-all patch management, manganese fertility, creeping bentgrass, and evidence-based turfgrass science, this is a must-watch discussion. #turfgrass #takeallpatch #manganese #soilscience #bentgrass #golfcoursemanagement #turfgrassscience  📌 https://www.gofundme.com/f/TurfgrassEpistemology Thank you for being part of this community and for supporting evidence-based turfgrass science.

S4 E29 Can Silicon Reduce Turfgrass Disease?

In this video, I break down the study “Evaluation of Calcium Silicate for Brown Patch and Dollar Spot Suppression on Turfgrasses.” We examine whether calcium silicate (Si fertilizers) actually suppress turfgrass diseases like brown patch and dollar spot. The results show that calcium silicate did not reduce dollar spot and, in some cases, actually increased brown patch severity, likely due to nutrient imbalances rather than any true disease suppression effect. If you're interested in silicon fertilizers, disease control, and evidence-based turfgrass management, this is a must-watch breakdown. #turfgrass #dollarspot #brownpatch #soilscience #fertilizer #turfgrassscience #golfcoursemanagement  📌 https://www.gofundme.com/f/TurfgrassEpistemology Thank you for being part of this community and for supporting evidence-based turfgrass science.

S4 E28 Does Biological Disease Control Work on Turfgrasses?

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 Podcast https://podcasts.apple.com/us/podcast/turfgrass-epistemology/id1717271379 Spotify Podcast https://open.spotify.com/show/1cTpdrChToeEFAOX9wkXFI iHeart Radio Podcast https://www.iheart.com/podcast/1323-turfgrass-epistemology-129043524/ Podbean https://turfgrassepistemology.podbean.com/ Online consulting Calendly.com/TravisShaddox Twitter Twitter.com/TravisShaddox Email TravisShaddox@gmail.com Turfgrass Programs and Extension Service Information: https://www.usna.usda.gov/assets/images/as_pdf_image/LandGrantColleges.pdf

S4 E27 Tinfoil Turfgrass - 35 Years of Experience. 35 Years of Bullsh*t.

In this video, I break down a lawn care discussion on nitrogen fertilizers and turfgrass performance, separating what’s scientifically sound from what may be oversimplified. We take a closer look at how nitrogen source, timing, and application strategy actually influence turfgrass growth—and whether the claims being made hold up under turfgrass science and soil fertility principles. If you're trying to better understand lawn fertilizers, nitrogen management, and turfgrass health, this video will help you make more informed, evidence-based decisions. #turfgrass #lawncare #fertilizer #nitrogen #soilscience #turfgrassepistemology #lawntips 📌 https://www.gofundme.com/f/TurfgrassEpistemology Thank you for being part of this community and for supporting evidence-based turfgrass science.

S4 E26 Tinfoil Turfgrass - How to With Steve and BS Booster!

In this video, I break down the “DirtBooster Organic Lawn and Garden Treatment” video from How to With Doc and take a closer look at the claims around soil microbes, biochar, humic substances, and “super compost.” The product is promoted as a way to rapidly build soil biology using ingredients like biochar, molasses, and microbial additives, but does the science support the idea that this translates into better turfgrass performance? We evaluate the logic, the mechanisms being implied, and whether these types of organic amendments actually deliver measurable benefits in turfgrass systems, lawn care, and soil management. #turfgrass #lawncare #soilscience #organicfertilizer #biochar #humicacid #turfgrassepistemology Become a member of Turfgrass Epistemology and support turfgrass research: www.youtube.com/@TurfgrassEpistemology/join Voicemail: 859-444-4234 Apple Podcast https://podcasts.apple.com/us/podcast/turfgrass-epistemology/id1717271379 Spotify Podcast https://open.spotify.com/show/1cTpdrChToeEFAOX9wkXFI iHeart Radio Podcast https://www.iheart.com/podcast/1323-turfgrass-epistemology-129043524/ Podbean https://turfgrassepistemology.podbean.com/ Online consulting Calendly.com/TravisShaddox Twitter Twitter.com/TravisShaddox Email TravisShaddox@gmail.com Turfgrass Programs and Extension Service Information: https://www.usna.usda.gov/assets/images/as_pdf_image/LandGrantColleges.pdf
