|Plant Nutrition & Nutrient Management||3|
Course Number: HORT 824
Macro- and micronutrient elements and their function in the growth and development of plants; the role of single elements; interaction/balances between elements and nutrient deficiency/ toxicity symptoms as they affect the physiology of the whole plant; and the relationship between crop nutrition and production/environmental considerations (e.g. yield, drought, temperature, pests). (Cross-listed as AGRO 824)
Course Number: HORT 842B
Presents fundamental concepts underlying the science of crop physiology, including crop phenology, canopy development and light interception, photosynthesis and respiration, and dry-matter partitioning.
Course Number: HORT 843K
This course focuses on the physiological principles and industry practices in the production, moving, care, and maintenance of ornamental trees, shrubs and ground covers. The purpose of this course is to provide students with the career tools to install and maintain woody plants. This goal will be accomplished through the review of the pertinent literature and through class exercises designed to improve students’ skills and knowledge of woody plant physiology, care and maintenance.
Course Number: HORT 896
Presents fundamental concepts underlying the science of crop physiology, including crop phenology, canopy development and light interception, photosynthesis and respiration and dry-matter partitioning.
|HORT 817 OR HORT 842A||3|
HORT 817: Plant Pathology: Principles & Applications or HORT 842A Plant Pathology
|Management of Horticultural Crop Insects||3|
Course Number: ENTO 803
Prereq: Introductory course in biology. Credit toward the degree cannot be earned in both ENTO 303 and ENTO 403/803. Biology, ecology and management of insect pests of horticultural crops such as vegetables, fruit trees, trees and shrubs, greenhouse crops, turf and ornamentals. Employs IPM strategies to maintain pests below damaging levels while minimizing the use of traditional insecticides.
|Entomology and Pest Management||3|
Course Number: ENTO 812
Prereq: Introductory course in entomology. Principles and practices of managing insect pests. Pest management theory, use of sampling, evaluation, tactics, types of insect pests, and current issues.
|Turf Disease Management||1|
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 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.
