This online graduate certificate in Ornamental, Landscape and Turf offers a selection of courses that focus on the turf and landscape aspect of horticulture. Core courses lend a solid science background providing the student with a greater understanding of how to manage turf and ornamental areas. This basic knowledge is then interwoven with situation-oriented disease, weed, and insect classes to help the practitioner advance his/her management knowledge.  Students who complete this certificate may also wish to pursue a Master of Science degree. 

This certificate is designed for:

  • Horticulturists employed in Extension programs
  • Golf course superintendents
  • City parks and recreation employees
  • Landscape maintenance practitioners
  • Those working in nursery/landscape-oriented garden centers

    HORT 814Turf Disease Management1

    Course Number: HORT 814

    Course focuses on diseases of grasses maintained as turf, emphasizing diseases that occur in the northern Great Plains of the U.S. In addition to strategies used in managing the diseases, the biology of the causal organisms and the influence of environmental conditions are examined.

    Course Number: HORT 843J

    The overall objective is to familiarize advanced students with the current state of knowledge on herbicide modes and mechanisms of action and recent developments by industry and universities in herbicide physiology. In this course, we will integrate plant anatomy, plant physiology, biochemistry, plant breeding, and principles of weed science as they relate to herbicide modes and mechanisms of action. This course is designed to examine how a herbicide molecule is absorbed (uptake) by plants, how it moves within plants (translocation), how it acts within plants (mode and mechanism of action), and the importance of metabolism as a means of selectivity between crops and weeds. This is not a course about weed identification, weed control recommendations, and weed management systems using biological, cultural, and chemical means.

    HORT 843MWeed Science4

    Course Number: HORT 843M

    In this course we will study weeds and weed control methods in agronomic and horticultural crops and turf grass with an emphasis on chemical weed control. The course is divided into lecture and laboratory sections. The lecture portion will count three-fifths (3/5) of your total grade and the laboratory will count two-fifths (2/5). In lecture, we will discuss the history of weed control, weed characteristics, weed competition, and methods of weed control including mechanical, cultural, biological, and chemical. Herbicides will be discussed by family with specific regard to their chemical structure, efficacy, mode and mechanism of action, crop selectivity, soil activity and persistence, and cost. In lab, we will examine the practical aspects of weed control including weed seed and plant identification, sprayer equipment, sprayer calibration, herbicide formulations, herbicide labels, crop/weed response to herbicides and injury symptomology, and Worker Protection Standards.

    Course Number: HORT 844B

    Physiology of plant responses to environmental stresses, with emphasis on current research in selected physiological, molecular, and biochemical mechanisms for tolerance to environmental stresses such as temperature extremes, drought, salt, pathogens and other plants.
