GAP Crop Production & Protection 2 — Questions and Answers
Question 1: What is the primary purpose of crop rotation in GAP-certified operations?
- Increase irrigation frequency
- Break pest and disease cycles while improving soil health (Correct answer)
- Reduce the need for harvest equipment
- Eliminate the need for fertilizers entirely
Correct answer: Break pest and disease cycles while improving soil health
Crop rotation disrupts pest and disease cycles and helps maintain soil fertility and structure.
Question 2: Under GAP guidelines, what is the minimum buffer zone typically recommended between a field and a livestock operation to reduce contamination risk?
- 10 feet
- 25 feet
- 50 feet (Correct answer)
- 120 feet
Correct answer: 50 feet
A 50-foot buffer zone is commonly recommended to reduce the risk of pathogen transfer from livestock to produce.
Question 3: Which method of pest identification is most consistent with Integrated Pest Management (IPM) principles under GAP?
- Applying pesticides on a fixed calendar schedule
- Scouting fields regularly to monitor pest population thresholds (Correct answer)
- Using the highest label rate to ensure effectiveness
- Treating all fields equally regardless of pest pressure
Correct answer: Scouting fields regularly to monitor pest population thresholds
Regular field scouting to monitor pest levels against action thresholds is the foundation of IPM under GAP.
Question 4: A GAP auditor finds that a grower applied a pesticide two days before harvest, but the label requires a 7-day pre-harvest interval (PHI). What is the likely consequence?
- The crop must be tested before sale
- The product is compliant if yield is normal
- This is a critical violation that can result in audit failure (Correct answer)
- The PHI only applies to organic operations
Correct answer: This is a critical violation that can result in audit failure
Violating the pre-harvest interval on a pesticide label is a critical food safety violation under GAP and can result in audit failure.
Question 5: What does 'restricted-entry interval' (REI) mean on a pesticide label?
- The time before the pesticide can be mixed with water
- The period workers must stay out of treated fields after application (Correct answer)
- The maximum number of applications per season
- The distance required between application equipment and water sources
Correct answer: The period workers must stay out of treated fields after application
The REI is the period after pesticide application during which entry into the treated area is restricted to protect worker health.
Question 6: Which soil amendment practice requires the longest wait time before harvest under most GAP standards when applied to soil for produce crops?
- Synthetic fertilizer
- Compost that has been properly treated
- Raw or uncomposted manure (Correct answer)
- Composted yard waste certified free of pathogens
Correct answer: Raw or uncomposted manure
Raw or uncomposted manure applied to soil typically requires a 120-day waiting period before harvest of crops with edible portions contacting the soil.
Question 7: What is a primary reason GAP standards require records of pesticide applications to be kept for a minimum period?
- To satisfy insurance company requirements
- To allow traceability in the event of a foodborne illness outbreak (Correct answer)
- To reduce the need for field scouting
- To qualify for government subsidies
Correct answer: To allow traceability in the event of a foodborne illness outbreak
Pesticide application records support traceability, enabling rapid investigation and response if a food safety incident occurs.
