Pre-harvest interval

Meaning in agriculture, with examples

nounAdvanced term

In agriculture, pre-harvest interval means: The minimum number of days that must pass between the last pesticide application and the harvest, as stated on the product label.

In Turkish: hasat öncesi bekleme süresi, son ilaçlama ile hasat arası süre

How it is used

Shortened to PHI. Growers, advisers and exporters check it carefully because harvesting too early can leave residues above the legal limit. Spray records must show that the pre-harvest interval was respected.

  2. The pickers started too early and ignored the pre-harvest interval, so the batch failed the residue test.
