Plant Production Major (B.Sc.(Ag.Env.Sc.)) (24 credits)
Offered by: Plant Science (Faculty of Agricultural and Environmental Sciences)
Degree: Bachelor of Science (Agricultural and Environmental Sciences)
Program credit weight: 24
Program Description
This specialization provides students with the knowledge and skills relating to the biology and physiology, breeding, propagation, and management of domesticated plants. The plant industry, in both rural and urban settings, is a sector of growing importance to Canadian and global economies. Graduates are prepared for employment in horticulture or in field crop development, production, and management, in government services, extension, teaching and consulting; or for graduate and postgraduate studies. When taken in conjunction with the Major Agro-Environmental Sciences and the specialization in Professional Agrology, this specialization conforms with the eligibility requirements for the Ordre des agronomes du Québec.

Required Courses (18 credits)
| Course | Title | Credits |
|---|---|---|
| PLNT 300 | 3 | |
Terms offered: this course is not currently offered. | ||
| PLNT 305 | Plant Pathology. | 3 |
Plant Pathology. Terms offered: Fall 2025 The theory and concepts of plant pathology, including the disease cycle, infection, symptoms, resistance, epidemiology and control. The biology and taxonomy of pathogens will be studied, including fungi, bacteria, viruses and nematodes. Techniques of inoculation, isolation of pathogens from diseased plants, disease diagnosis and pathogen identification will be demonstrated. | ||
| PLNT 310 | Plant Propagation. | 3 |
Plant Propagation. Terms offered: Winter 2026 Principles and practical aspects of plant propagation are examined. The course consists of two parts. The first third deals with sexual propagation; the production, processing storage certification and analysis of seeds. The remaining two-thirds deals with vegetative propagation; cutting, budding, grafting, layering, and tissue culture. | ||
| PLNT 353 | Plant Structure and Function. | 3 |
Plant Structure and Function. Terms offered: Winter 2026 The general anatomy and physiology of vascular plants with emphasis on how physiological processes influence function. | ||
| PLNT 434 | Weed Biology and Control. | 3 |
Weed Biology and Control. Terms offered: Winter 2026 A study of the biology of undesirable vegetation as related to the principles of prevention and physical, biological, managerial and chemical control. Emphasis on the environmental impact of the different methods of weed control. | ||
| PLNT 435 | Plant Breeding. | 3 |
Plant Breeding. Terms offered: Winter 2026 Principles and practices of plant breeding, including reproduction of crop plants; plant hybridization; sources of genetic variation; selection methods used for self- and cross-pollinated crops and for clonally reproduced crops; breeding for diseases and pest resistance; applications of biotechnology in plant breeding. | ||
Complementary Courses (6 credits)
6 credits of complementary courses selected from:
| Course | Title | Credits |
|---|---|---|
| AGRI 340 | Principles of Ecological Agriculture. | 3 |
Principles of Ecological Agriculture. Terms offered: Winter 2026 Focus on low-input, sustainable, and organic agriculture: the farm as an ecosystem; complex system theory; practical examples of soil management, pest control, integrated crop and livestock production, and marketing systems. | ||
| ENTO 352 | Biocontrol of Pest Insects. | 3 |
Biocontrol of Pest Insects. Terms offered: Winter 2026 Modern concepts of integrated control techniques and principles of insect pest management, with emphasis on biological control (use of predators, parasites and pathogens against pest insects), population monitoring, and manipulation of environmental, behavioral and physiological factors in the pest's way of life. Physical, cultural, and genetic controls and an introduction to the use of non-toxic biochemical controls (attractants, repellents, pheromones, antimetabolites). | ||
| PLNT 302 | Forage Crops and Pastures. | 3 |
Forage Crops and Pastures. Terms offered: Fall 2025 Ecology, management, and physiology of forage crops with emphasis on establishment, growth, maintenance, harvesting, and preservation; value as livestock feed in terms of nutritional composition and role in environmental conservation. | ||
| PLNT 307 | Agroecology of Vegetables and Fruits. | 3 |
Agroecology of Vegetables and Fruits. Terms offered: Fall 2025 Application of ecological concepts and principles to the design and management of selected vegetable and fruit agroecosystems. Includes selection of varieties and management from seedling to harvest to storage. | ||
| PLNT 312 | Urban Horticulture. | 3 |
Urban Horticulture. Terms offered: Winter 2026 Selection, use and care of plants in urban environments for the benefit of urban populations: landscape design, turf and green space management, urban trees, green roofs and walls, design and management of community gardens, urban agriculture. | ||
| PLNT 322 | Greenhouse Management. | 3 |
Greenhouse Management. Terms offered: Winter 2026 The production of major flower and vegetable crops in greenhouses. Includes greenhouse design, heating, ventilation, lighting, hydroponics, irrigation, fertilization, scheduling and integrated pest management. | ||
| SOIL 535 | Soil Ecology. | 3 |
Soil Ecology. Terms offered: Fall 2025 Exploration of the unique soil habitat for organisms with a focus on the variables that affect the abundance, diversity and interactions of soil biota and, in turn, their influence on soil physicochemical properties, biogeochemical cycles and other factors impacting ecosystem sustainability. Topics include survey of soil fauna, soil food webs, microbial ecology, biological carbon and nitrogen cycling, plant-soil interactions, and the effects of human activities and management on soil ecology, including synthesizing concepts and a critical analysis and interpretation of primary scientific literature in soil ecology. | ||
