Excerpt

The Pre-Harvest Interval and Re-Entry Interval dictate how long to wait after spraying a block before it can be safely harvested or re-entered.

PHI (Pre-Harvest Interval)

The time interval (in hours) that must pass after spraying a chemical before the block can be safely harvested. You can choose to receive a notification after this interval has passed when recording a spray event.

Harvest events will indicate whether the pre-harvest interval has passed for each block being harvested.

REI (Re-Entry Interval)

The time interval (in hours) that must pass after spraying a chemical before workers can safely enter the block area. You can choose to receive a notification after this interval has passed when recording a spray event.

Harvest events will indicate whether the re-entry interval has passed for each block being harvested.


Warning

Field Packing and Production Practices involving re-entry will not warn you if the PHI or REI have not passed.

Viewing PHI/REI Status

Detailed PHI/REI information can be found in the following reports:

  • PHI/REI Report - The current PHI/REI for each block, and whether it has been passed.
  • Block PHI-REI Map - A map displaying whether the PHI/REI has been passed for each block.
  • PHI/REI Crop List Report - A list of the current PHI/REI of each crop for each chemical.

If the PHI/REI date has passed, it will appear blue with a checkmark.

Setting the PHI/REI

Each chemical has a different PHI and REI for each crop. See How to Add a Chemical or (Placeholder) How to Create a New Version of a Chemical to set a chemical's PHI and REI for each crop.
