What does the term pre-harvest interval describe in pesticide labeling?

• A. The amount of time a crop can be harvested after it has been sprayed
• B. The maximum storage period after opening
• C. The minimum application interval
• D. The number of days before planting next crop

Answer: (A)

The term describes the waiting period between spraying a crop and harvesting it. It’s the minimum number of days that must pass after the last pesticide application to ensure residues stay within legal limits and are safe for consumption. This interval is specific to each product and crop and is printed on the label as the PHI. It’s not about how long you can store the product, how often you must apply it, or when you plant the next crop. It’s also different from the restricted-entry interval, which relates to worker safety. So, the PHI is the official no-harvest-before-x-many-days-after-application rule you must follow.
