In certain packinghouse situations, pesticide mixtures are included in the treatment regime. As in other situations, it is important to minimize the amount of mixture created so there is little to no excess remaining. If a pesticide-containing mixture cannot be used in accordance with label directions, it must be evaluated by the applicator as to its waster classification before its disposition is determined. Some pesticide-containing mixtures can be disposed of directly through sewage treatment facilities. However, this depends on the specific facility and therefore requires that local authorities be notified and permission obtained. Permits may be required. Other pesticide-containing mixtures may be regulated as wastewaters, solids, or hazardous wastes (click here to view helpful information about hazardous waste). Many states regulate the various wastes from packinghouses through other agencies in the state government.
