  • S4 E32 Bandwagon Appeal and Social Pressure
    Jun 25 2026

    Why do people conform to group pressure even when they know the group is wrong? In this video, we explore Solomon Asch's landmark conformity study, Opinions and Social Pressure (1955), and reveal what his famous experiments teach us about social influence, peer pressure, independent thinking, and human psychology.

    Paper: Opinions and Social Pressure (1955) Author: Solomon E. Asch

  • S4 E31 Dr. Jada Powlen - Summer Nitrogen on Tall Fescue?
    Jun 23 2026

    Does summer nitrogen really make brown patch worse in tall fescue? In this interview, Dr. Jada Powlen discusses her 2024 study and explains why cultivar selection may be more important than nitrogen rate for managing brown patch disease.

    Paper: Brown patch severity of five tall fescue cultivars as influenced by summer nitrogen rates (2024) Authors: Jada S. Powlen, James P. Kerns, Michael A. Fidanza, and Cale A. Bigelow

  • S4 E30 Does Manganese Influence Take-All Disease?
    May 28 2026

    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.
