In this episode of Turfgrass Epistemology, I sit down with Dr. John Inguagiato to discuss his peer-reviewed research on phosphite use for suppressing cyanobacteria (blue-green algae) on putting greens. Together, we break down the science behind phosphite chemistry, application rates, turf safety, and what the data actually say—beyond marketing claims.
Dr. Inguagiato’s 2017 Crop Science paper, “Effect of Phosphite Rate and Source on Cyanobacteria Colonization of Putting Green Turf,” is one of the most frequently cited studies on this topic. In this conversation, we explore how phosphite differs from phosphate, why cyanobacteria respond differently to these compounds, and how phosphite applications can reduce algal crusting without relying solely on traditional fungicides
This discussion covers:
If you manage putting greens, work in turfgrass research, or want an evidence-based explanation of phosphite products that cuts through anecdote and advertising, this episode provides critical context straight from the study’s lead author.
