    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.

    HORT 842APlant Pathology3

    Course Number: HORT 842A

    Survey of the principles and practices of plant pathology. The main and genetic elements involved in plant disease will be covered. Many of the major diseases, as well as their causes and effects, will be surveyed.

    HORT 843JHerbicides and Weed Management Systems4

    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.
