Restricted Entry Interval (REI) is the period of time after a pesticide has been applied that agricultural workers or anyone else must not do hand labour tasks in treated areas. The REI allows the pesticide residues and vapours to dissipate to safe levels for work to be done. Hand labour tasks involve substantial worker contact with treated surfaces such as plants, plant parts or soil. Examples of these activities include: · harvesting, detasseling, thinning, weeding, scouting, planting, mowing, roguing, and packing produce into containers in the field or greenhouse. You can only do these tasks after the Restricted Entry Interval has ended.
