AGA 381 - Crop Scouting
3 Credits
Total Lecture Hours: 30
Total Lab Hours: 30
Course Description:
This course focuses on identification of pest problems in crops and on developing an integrated pest management program. Students learn to utilize economic thresholds in recommending control methods that are vital to the economic and environmental needs in the industry. Students also learn to prevent potential fertility, pest, and environmental problems with crop production practices. Upon competition of this course students will have developed many critical thinking and hands-on learning experiences that will be beneficial in the industry.
