Need a refresher on restricted-entry intervals (REI) and preharvest intervals (PHI)? The PMRA has published a couple of short factsheets that do a good job of explaining exactly what is required by growers.
The REI factsheet provides some clarity around what can and cannot be done during the REI and is a must-read for anyone who has their fields scouted or performs any hand labour (harvesting, weeding, scouting etc.).
Maybe print off a copy and throw it up in your barn or shop but definitely check them out before the spraying season really picks up.
