Multiple stresses, plant health, and plant health promoting products will also be discussed.

Dr. Paul Koch teaches this course which provides a comprehensive introduction to the primary diseases of cool-season turfgrass. Students will learn how to identify diseases, receive the most up-to-date research related to integrated disease control strategies, and work to develop comprehensive disease control programs specific to their location.

Dr. Jim Kerns leads this course which provides a comprehensive introduction to the primary diseases of warm-season turfgrass. Students will learn how to identify diseases, receive the most up-to-date research related to integrated disease control strategies, and work to develop comprehensive disease control programs specific to their location.

This course is taught by Dr. Ben McGraw. The class is designed to provide a fundamental understanding of the basics of entomology, an extensive overview of the major cool- and warm-season turfgrass insect pests, and integrated pest management strategies for their control. A major emphasis of this class will be on identification and behavior of key turfgrass pests. Chemical management will be covered in-depth and the latest findings from university led research will be covered.

Dr. Kerns leads this course which focuses on turfgrass integrated pest management, the diagnostic process in turfgrass systems, resistance management, disease epidemiology, principles of disease management and cultural control strategies.

This six-week course will address management and communication science as it applies to leadership roles in golf and sports turf.
  • The first two weeks will focus on the manager's role as communicator and the brand, or message, the manage conveys staff and stakeholders.
  • The second two weeks will focus on managing the message and making sure the right information has the intended effect.
  • The final two weeks will focus on using management and communication skills to achieve optimal outcomes - in other words, leadership skills.

The in-person, online discussions not only will cover the content of the course, but also will allow participants to discuss and explore management challenges specific to their roles and responsibilities in the industry.

Part II: Manager as Informer. Expository writing—informing the reader/listener—is focused on the message. Many operations and tasks in greenkeeping are foreign to staff and clientele. An important skill for any manager is to clearly communicate the operation’s mission and improve its workflow. Presenting clear and concise information is the goal here. Requires Mastering Mgmt & Communication I.

Manager as Influencer. Effective leadership is demonstrated in the ability to influence the culture and success of your operation. Effective leadership requires understanding how people behave and work as a group, and then moving the group toward the organization’s visionary goals. The required reading will address leadership skills that require empathy, negotiation, strategy, and decision-making. The outcome will be to produce a publishable article in a newsletter or on social media. Requires Mastering Mgmt & Communication II.

Precision turfgrass management uses observations, data, and models to improve management efficiency in turfgrass systems. This course will cover turfgrass growth potential, various turf and pest models, manipulation of growth with nitrogen and PGR programs, clipping volume, crop sensors, mapping date and construction of prescription maps for precision applications with variable rate sprayer systems.

Dr. Paul Koch leads this important course on responsible pesticide use in turfgrass systems. Topics will include pesticide toxicity, use BMPs, measuring pesticide risk, organic and pesticide alternatives. The course also focuses on disease models to time fungicide applications. Students will finish the course with awareness of IPM goals and ways to document progress achieving those goals.

It's been said that common sense and drainage are needed to grow turf. And, if short on the former, than add more of the latter. This course covers various aspects of turfgrass drainage including slope, soils, layers, root zone construction, drainage technologies and cultivation techniques to improve drainage.

This course will cover various aspects of turfgrass fertilization including a thorough examination of nitrogen fertilizer, other secondary and micronutrients, cost-benefit of different fertilizer sources, nutrient demand & clipping volume, and the impact of fertilizer in the environment.
