Full course description
This course provides an in-depth exploration of weed biology, ecology, and management practices within turfgrass environments. Weeds are not merely unwanted plants—they are biological competitors that undermine turfgrass quality, safety, and sustainability in both recreational and professional landscapes. Students will develop the ability to identify key weed species common to athletic fields, lawns, parks, and golf courses, and will examine the environmental and mechanical factors that contribute to weed establishment and spread.
The curriculum introduces foundational concepts in weed classification, plant morphology, and life cycles, with emphasis on the differences between grassy and broadleaf weeds, annuals vs. perennials, and cool- vs. warm-season invaders. Students will analyze the ecological dynamics that allow certain weeds to dominate, including light competition, soil disturbance, nutrient imbalances, and turfgrass mismanagement.
A major focus of the course is Integrated Weed Management (IWM), which incorporates cultural, mechanical, biological, and chemical control methods. Students will evaluate pre- and post-emergent herbicide technologies, active ingredient classifications, and resistance management strategies aligned with environmental and regulatory best practices. Field-based scenarios and case studies will challenge students to design weed management plans tailored to sports turf, commercial landscapes, and institutional grounds.
