Re-entry period
Some pesticides are very poisonous when they are first applied to a crop. A certain amount of time must pass before it is safe to go into the field. This waiting time is called the re-entry period. You should be given a written or spoken warning not to go into the field without special protective clothing until the re-entry period is up. If you must enter a field before the re-entry period is up, it is recommended you wear the same amount of protective clothing and equipment that the pesticide ground applicator is required to wear.
