Fighting Powdery Mildew With UV Light & Breeding Hemp for Better Grain and Fiber

On this week’s Hemp Show, we’re back at Cornell Agritech for part three of my Cornell trilogy. In this episode I visit plant pathologist Jane Hamilton, who’s testing UVC light as a non-chemical tool against powdery mildew, and Luis Monserrate from Larry Smart’s breeding program, where seed size, yield and chemotype drive decisions for grain and fiber growers. Next, we walk through Jane’s UV cabinet and the powdery mildew chamber, talking dose windows and why powdery mildew (unlike some fungi) doesn’t have melanin to block UV. Then it's over to Luis for small-plot yield math, why bigger seeds can jump-start canopy closure and how chemotype IV lines can keep hempseed meal within ultra-low cannabinoid limits.
