NIGP 19243: Herbicides and Other Poisons, Cleaning Agents (Used to Clean Spray Equipment)

NIGP 19243 Herbicides and Other Poisons, Cleaning Agents (Used To Clean Spray Equipment) is an Item code covering chemical vegetation control products, liquid and dry herbicides, aquatic herbicides, adjuvants, surfactants, and ornamental products that state and local governments procure to manage invasive species, weeds, and unwanted vegetation at facilities, rights-of-way, parks, drainage structures, and natural areas. Recent solicitations reveal two distinct procurement streams: master agreements and blanket purchase orders for on-call herbicide and pesticide supply across multiple city departments and state agencies, and specialized vegetation management contracts that bundle chemicals with application services and professional expertise. State and local governments also procure cleaning agents used to decontaminate spray equipment following herbicide application. Issuing bodies include city procurement offices, county boards of commissioners, state departments of enterprise services, and municipal utilities managing streets, highways, forestry areas, nurseries, and mitigation sites.
