AGA 381 - Crop Scouting

Credits: 3
Lecture Hours: 2
Lab Hours: 2
Practicum Hours: 0
Work Experience: 0
Course Type: Open
The course develops an understanding of the factors that affect plant growth. Plant nutrients are considered as students gain experience in identifying major and micronutrient deficiency symptoms in plants by means of soil tests, plant tests and observations.
Competencies
  1. Evaluate crop scouting basic techniques, tools and testing.
    1.  Identify fundamentals concepts of integrated pest management.
    2. Assess economic thresholds and Injury levels.
    3. Develop crop-scouting schedules that include frequency of scouting and patterns used.
    4. Take part in the collection and shipment of plant and soil samples.
    5. Construct a general scouting report.
    6. Identify basic tools used to crop scout grain and forage crops. 
  2. Estimate grain and forage crop growth stage and development
    1. Identify crop anatomy and morphology of grain and forage crops.
    2. Analyze growth developmental stages for grain and forage crops.
    3. Estimate grain and forage crop plant populations.
    4. Make use of growing degree-days to predict the timing of plant development. 
    5. Utilize a management calendar to crop scout grain and forage crops.
    6. Distinguish the developmental growth stage of corn and soybean plants 
  3. Judge biotic factors that affect crop growth and development 
    1. Identify common grain and forage crop insects, their morphology and life cycles 
    2. Identify common beneficial insects of grain and forage crops.
    3. Identify common grain and forage crop diseases 
    4. Apply the disease triangle to assess crop disease development
    5. Summarize common grain and forage crop weeds, their morphology and life cycles
    6. Evaluate pest injury levels and make management recommendations to minimize economic damage.
    7. Recommend crop pest prevention and management strategies. 
  4. Evaluate abiotic factors that affect grain and forage crop’s growth and development. 
    1. Identify nutrient deficiencies in grain and forage crops.
    2. Analyze soil with good structure with compacted soil.
    3. Summarize how crop injury can occur due to pesticide drift and pesticide carry-over. 
    4. Identify mechanical crop damage on grain and forage crops.
    5. Evaluate fertilizer burn on grain and forage crops.
    6. Apply a diagnostic field guide to identify grain and forage crop problems. 
  5. Propose management strategies to prevent or minimize pesticide resistance. 
    1. Identify how pesticide resistance occurs
    2. Evaluate integrate pest management strategies prior to selecting pesticides.
    3. Compare the mode of action of pesticides used to control crop pest.
    4. Contrast the types of applications methods used to place pesticides.
    5. Determine timing of pesticide applications and make defendable pesticide product recommendations.
    6. Interpret current federal and state pesticide laws as they pertain to pesticide used on grain and forage crops in Iowa.
  6. Appraise the need and use of precision agriculture technology used in crop scouting. 
    1. Identify the various uses of GPS in crop scouting.
    2. Outline the economics of precision agriculture used in crop scouting. 
    3. Practice mapping an area using a hand-held GPS unit.
    4. Demonstrate the operation of a drone to collect crop scouting information. 
    5. Save date into memory and export to computer application to create a written scouting report.
    6. Identify computer applications that can visually identify pest organism in the field.
