AGRI 218 - Weed Identification and Control
PROGRAM: Agriculture
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 2
LAB HOURS MIN: 2
DATE OF LAST REVISION: Fall, 2019
Identification and control of the economically important broadleaf and grass weeds that impact agricultural production in the U. S. Identification of seeds, seedlings and full-grown plants is addressed. Weed control programs are examined in the context of herbicide chemistry, timing and economics. Emphasis is placed on pesticide formulations, application methods, rate calibration, environmental concerns, safety, laws and regulations. Students will participate in training for and receive a Certified Pesticide Applicators Permit as part of the course requirements.
MAJOR COURSE LEARNING OBJECTIVES: Upon successful completion of this course the student will be expected to:
- Identify the major weed species, at various growth stages that affect agricultural production in the Midwest.
- Understand the differences in herbicide programs from a weed control and an economic standpoint.
- Evaluate sprayer configurations for obtaining maximum control of different weeds at different growth stages.
- Calculate rates of application for different formulations of pesticides, and calibrate sprayers to obtain correct application rates.
- Understand the current laws regarding pesticide usage and storage.
- Pass the Indiana Pesticide Applicator Core Exam and obtain a Pesticide Applicator Permit.
COURSE CONTENT: Topical areas of study include -
- Identification of weed seeds, seedlings, and mature plants
- Weed life cycles
- Field scouting to determine weed pressure
- Mechanical and chemical means of weed control
