Case studies are an effective way to demonstrate real-life issues growers face and to showcase solutions to resolve them. As a technical specialist, we help growers from all walks of life, ranging in size and production scheme. This session will outline various case studies of common abiotic and biotic issues seen in the greenhouse with strategies you can use to enhance your diagnostic capabilities. Each case study will accompany present-day cultural/chemical/biological/nutritional recommendations for management and prevention.

Why My Weeds Won't Die: Understanding Herbicide Resistance and Other Factors Contributing to Failed Herbicide Applications 

 Dr. Kurt Vollmer, University of MD Wye Research & Education Center

Herbicide resistance has been documented in at least 14 species in Maryland, with only 4 having been documented as being glyphosate-resistant.  However, 90% of all herbicide failures can be attributed to factors other than resistance. This presentation will discuss how weeds develop resistance, ways to tell if resistant weeds are present, and external factors that can contribute to herbicide failures.
