The contract for Marshall County Weed Spraying, issued by the South Dakota Department of Transportation under solicitation number 000n-151, calls for the application of herbicides along state highway right-of-ways within Marshall County to control noxious vegetation. The work requires two annual applications—one in spring and another in late summer to early fall—timing determined by product labels and approved by the Maintenance Supervisor. The contract specifies exact quantities and unit prices for six approved herbicides including 24D, Tordon 22K, Sahara, Roundup Custom, Escort, and Velpar L, along with labor and equipment hours, resulting in a fixed total contract value of $30,606.40. All spraying operations must comply with manufacturer-recommended application rates, be performed by personnel certified by the South Dakota Department of Agriculture, and be documented daily using the DOT 820 form, which is mandatory for payment processing.
