AGRI 216 - Disease and Insect Identification and Control
PROGRAM: Agriculture
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 2
LAB HOURS MIN: 2
DATE OF LAST REVISION: Spring, 2019
Identification and control of the economically important diseases and insects that impact agricultural production in the U. S. Emphasis is placed on disease pathogens and insects that affect grain and forage production in the Midwest. Current technologies in chemical control as well as integrated pest management will be explored with emphasis on environmental and personal safety.
MAJOR COURSE LEARNING OBJECTIVES: Upon successful completion of this course the student will be expected to:
- Identify the important fungal pathogens that infect corn, soybean, small grain and forages.
- Understand the economic and health effects of plant diseases in grain and forage.
- Understand the cultural practices that discourage the infection and spread of plant diseases.
- Evaluate variety descriptions for genetic resistance and tolerance to diseases.
- Understand the types of pesticides available to prevent and cure plant diseases.
- Identify the important insects, mites and nematodes that cause economic losses in crops and forage.
- Understand the concept of economic threshold in evaluating insect infestations.
- Understand current biotech traits that provide resistance to insect feeding.
- Be familiar with the classes of pesticides used to control agricultural insect pests.
COURSE CONTENT: Topical areas of study include -
- Identification of rots, wilts and foliar diseases in grain and forage crops.
- Effect of weather, tillage, irrigation and other factors on the infection and spread of plant pathogens.
- Pathogenic fungus life cycles
- Breeding for disease resistance and resistance ratings.
- Classes of fungicides and the importance of fungicide rotation to prevent resistance.
- Identification of the larval and adult forms of important plant-feeding insects, mites and nematodes.
- Insect populations and their relationship to economic losses in grain and forage crops.
- Insect life cycles.
- Genetic engineering products for control of insects.
- Human health effects of insecticides and fungicides and applicator safety.
- IPM in insect control.
