NIGP 67590: Liquid Formulation Herbicides

NIGP 67590 Liquid Formulation Herbicides, Item, represents products state and local governments procure for roadside and right-of-way vegetation management, easement maintenance, invasive species control, airport weed suppression, and facility grounds upkeep. The actual buying under this code spans both direct supply of herbicide products—glyphosate, imazapyr, 2,4-D formulations, triclopyr, diquat bromide, fluridone, and specialty preemergent and selective compounds—and integrated service contracts that bundle herbicide application labor with product delivery. State departments of transportation and county public works departments dominate the issuing-body mix, with significant activity from cities, special water management districts, and airport authorities. Recent solicitations show counties and state DOTs using RFQs, RFPs, and ITBs to procure both products and services; Cobb County, Georgia has posted two separate easement maintenance rebids within the past six weeks, and Solano County and the Utah Department of Transportation have issued IFBs for herbicide supply with explicit product line-item pricing and delivery terms.

Georgia and California lead recent geographic activity, with multiple county and state-level solicitations. Solano County Department of Resource Management–Public Works issued IFB 675092127 in early October 2026 for agricultural chemicals (herbicides) with a local-vendor preference allowing local bidders within 5 percent to match the lowest bid; the contract runs November 1, 2026 through June 30, 2027 with optional two-year renewals, and covers 250 gallons of AquaMaster, 530 gallons of Vastlan, and smaller quantities of Milestone, Dimension 2EW, Esplanade 200 SC, and Gallery SC, plus training and annual recommendations. The Utah Department of Transportation issued IFB UDOT270012CN in early September 2026 for a five-year multiple award covering selective, non-selective, bareground, and preemergent herbicides statewide with 27 itemized line items and 15-day delivery windows; Cobb County, Georgia reissued easement maintenance services (PE77050NONST2027000000110) due October 22, 2026, including herbicidal applications within the Water System service area. Activity spans Texas (City of San Antonio, Texas Department of Criminal Justice, City of Dallas, Houston Airport System), Florida (Hillsborough County, Pasco County, St. Johns River Water Management District with estimated three-year spend of $6 million), and California (Caltrans in San Diego County, City of Milpitas), with Washington State Department of Enterprise Services managing a statewide vegetation management products contract vehicle worth $7.77 million cumulatively over four years.
