NIGP 67585: Dry Formulation Herbicides

NIGP 67585 Dry Formulation Herbicides, an Item code, covers the supply and application of solid and pelleted herbicide products for right-of-way maintenance, invasive species control, and vegetation management across transportation corridors, parks, drainage infrastructure, and utility rights-of-way. State and local governments are procuring dry herbicide formulations—including pelleted aquatic products, selective systemic compounds, and tank-mix adjuvants—alongside application labor, training, and annual recommendations. Recent solicitations span counties managing roadside vegetation, municipalities operating city parks and streets, state departments establishing statewide cooperative contracts, and special-purpose water and environmental districts controlling invasive aquatic species. Issuing bodies include county boards of commissioners (Solano County, White County, Hillsborough County), city procurement offices (Dallas, Milpitas), and state departments (Washington State Department of Enterprise Services, Illinois Department of Natural Resources). The code also encompasses blanket purchase orders for MRO supplies where dry herbicides appear as a line item alongside landscaping chemicals and grounds-maintenance materials.

Activity spans California, Georgia, Florida, Washington, Texas, and Illinois. Solano County Department of Resource Management–Public Works issued an IFB for agricultural chemicals including 250 gallons of AquaMaster, 530 gallons of Vastlan, and adjuvants for roadside right-of-way maintenance, with bids due November 4, 2026 and a local-vendor preference allowing local businesses within 5% of the low bid to match price. Hillsborough County Board of County Commissioners procured herbicide spraying and planting services for invasive species and weed control at mitigation sites and drainage structures under a three-year contract valued at $544,532.50, with bids due August 3, 2026 and Florida Department of Agriculture licensure required. Washington State Department of Enterprise Services solicited bids for a statewide vegetation management contract vehicle covering liquid and dry herbicides, aquatic herbicides, and adjuvants for state agencies and municipalities, with proposals due August 20, 2026, up to four main awards per category, and historical annual spending ranging from $914,419 to $3.87 million. The Illinois Department of Natural Resources procured Sonar One, a pelleted aquatic herbicide containing 5% fluridone, for freshwater vegetation control under a federal-assistance procurement funded through the Great Lakes Restoration Program, with bids due June 3, 2026.
