GAP Pest & Disease Management Flashcards

Which of the following cultural practices can reduce plant disease pressure on a GAP-certified farm?

Answer: Crop rotation to break disease cycles

Crop rotation disrupts the life cycle of soil-borne pathogens and reduces disease inoculum in the field.

Under GAP, what information must be on the label of a tank-mixed pesticide prepared for application?

Answer: Product names, EPA registration numbers, target pest, and applicator contact

Tank-mix containers must be clearly labeled with product identities and key application information to ensure safe and legal use.

A GAP auditor asks for evidence that re-entry intervals (REIs) are being followed. What record would satisfy this requirement?

Answer: Pesticide application logs with application date, product, and REI, plus field entry logs

Application logs with REI information and field entry logs together document that workers did not enter treated areas prematurely.

Which pest monitoring tool is used to detect insects by attracting them with a chemical signal that mimics a natural attractant?

Answer: Pheromone trap

Pheromone traps use synthetic sex or aggregation pheromones to lure target insects, enabling population monitoring without broad pesticide use.

What is the significance of the 'days to harvest' notation on a pesticide label in a GAP context?

Answer: It defines the minimum waiting period after application before the crop can be legally harvested

The days-to-harvest notation is equivalent to the pre-harvest interval (PHI), establishing the legal minimum wait before harvest to protect food safety.

Which of the following best describes an economic injury level (EIL) in the context of GAP pest management?

Answer: The pest density at which the cost of crop damage equals the cost of control

The EIL defines the pest population density at which the economic damage caused by pests equals the cost of implementing control measures.
