About this episode

This episode discusses the effectiveness of organic fertilizers in suppressing dollar spot disease in turfgrass and their impact on microbial populations.

In this video, I break down the classic study “Microbial Populations and Suppression of Dollar Spot Disease in Creeping Bentgrass with Inorganic and Organic Amendments.” We take a close look at whether organic fertilizers actually suppress dollar spot and how they influence microbial populations in turfgrass systems. The results show that while some organic amendments increased microbial activity, dollar spot suppression was inconsistent and often less effective than fungicides, with nitrogen and growth response playing a major role. If you’re interested in dollar spot control, soil microbes, organic vs synthetic fertilizers, and turfgrass disease management, this is a must-understand paper. #turfgrass #dollarspot #soilmicrobiology #fertilizer #turfgrassscience #golfcoursemanagement #IPM📌 https://www.gofundme.com/f/TurfgrassEpistemology Thank you for being part of this community and for supporting evidence-based turfgrass science.
