Major in Agricultural Biology, Weed Science Concentration

The Agricultural Biology major with a concentration in Weed Science provides a strong scientific foundation in weed science to address challenges in natural and managed systems. Students will gain tools to foster sustainability and address pressing issues involving biophysical and sociocultural components of these systems. The major features courses in agriculture, biology, and ecology as well as practical training through internships and/or research experiences. Students will also learn the complex interactions that occur among microbes, insects, and plant species in natural and managed ecosystems and develop skills to use systems thinking to solve real-world problems. Knowledge and skills gained from the major will enable students to identify and solve complex problems in natural and managed systems, especially in implementing effective and sustainable pest management.

Learning Objectives

1. Technical Competencies: Integrate skills and knowledge to solve problems related to plants, insects, and microbes in natural and managed ecosystems. Students will be able to apply knowledge of current technologies to:
   1. Identify important plants, insects, and microbes, integrating methods such as molecular approaches and ocular use of taxonomic keys. 
   2. Explain the biology and ecology of important pests and beneficial species. 
   3. Provide cost effective, socially acceptable, and environmentally sound pest management solutions.
2. Agricultural Literacy: Demonstrate understanding of social, economic, and biophysical aspects of the management of biological problems in natural and managed ecosystems:
   1. Identify participants and evaluate their roles in pest management policy, including regulatory frameworks. 
   2. Describe the similarities and differences among management of biological problems such as infestations of weeds, insect pests, and or disease in natural and managed ecosystems.
   3. Develop logical, objective, balanced arguments regarding contemporary issues in natural and managed ecosystems. 
   4. Explain the benefits and risks of management practices in natural and managed ecosystems.
3. Critical Thinking: Describe, assess, analyze, and synthesize knowledge from across the curriculum to create solutions for pests and beneficial species in natural and managed ecosystems:
   1. Describe critical problems and gaps in information for natural and managed ecosystems through assessment, analysis, and integration of facts. This includes the productivity and sustainability of these ecosystems and issues described in 2c above.
   2. Integrate, synthesize, and apply information from across the curriculum to create solutions to complex problems. Complex problems are challenges to productivity and sustainability of natural and managed ecosystems such as described in 2c above.
   3. Analyze qualitative (facts) and quantitative (numerical) information and derive conclusions about challenges in the productivity, sustainability, and management of natural and managed ecosystems.
4. Leadership: Promote and practice inclusion to form effective teams that solve complex problems in natural and managed ecosystems. 
   1. Function effectively within diverse teams to solve complex problems and achieve desired outcomes in natural and managed ecosystems.
   2. Create and facilitate inclusive and diverse teams.
5. Communication: Communicate effectively with diverse audiences regarding sustainable pest and pathogen management in natural and managed ecosystems:
   1. Excel in written and verbal communication of scientific results and analyses of information related to sustainable pest and pathogen management to diverse audiences including peers, stakeholders, public and the media.
   2. Engage stakeholders such as researchers, farmers, and industry representatives in the identification of pest and pathogen management needs.

Concentration-Specific Learning Objectives in Weed Science

Upon successful completion of the Weed Science Concentration, students will be able to:

1. Identify and classify weeds of economic importance in diverse systems.
2. Explain the mechanisms and causes of herbicide resistance.
3. Integrate basic and applied knowledge of weed science to develop effective weed management strategies in agricultural systems.

Potential Occupations

This major will be an excellent choice for students interested in careers as researchers, crop advisors, extension educators, growers, agriculture consultants, production managers, inspectors, diagnosticians, regulatory professionals and for those who wish to pursue careers in academia.

Select enough elective credits to bring the program total to 120, of which at least 42 must be Upper-Division (300- to 400-level).

Distinctive Requirements for Degree Program: Each course used to satisfy requirements of the major requires a minimum grade of 'C' (2.000).

To prepare for first semester: The curriculum for the Agricultural Biology major assumes students enter college prepared to take calculus. Entering students who are not prepared to take calculus will need to fulfill pre-calculus requirements in the first semester. Those pre-calculus requirements are listed as benchmark courses in Freshman Semester 1 below.
