Fungicides and Species Resistances Affects Dollar Spot

In this video, I analyze the 2025 Zhang et al. study on how fungicide scheduling and bentgrass cultivar resistance interact to influence dollar spot control. This research provides some of the strongest evidence to date that curative, damage-threshold-based fungicide programs can dramatically reduce inputs—up to 78 percent in certain cases—when paired with disease-resistant bentgrass cultivars. I explain how the researchers designed the field trials, what the low damage threshold means in practice, how 24-hour and next-application-day schedules performed differently, and why resistant cultivars such as Declaration produced such large savings without sacrificing control. I also discuss how inoculation affected disease pressure, why susceptible cultivars behaved differently, and what this means for superintendents trying to reduce fungicide use while maintaining high-quality fairways. If you want a clear, evidence-based explanation of how timing, cultivar resistance, and disease pressure shape fungicide performance, this video brings the science into focus. 🎓 Turfgrass Epistemology — How do we know what we know? 📌 https://www.gofundme.com/f/TurfgrassE...
