Whitetop 80% Costshare Program

The District is offering to provide herbicides to Big Horn County private landowners at an 80% costshare for treatments on whitetop. 

Costshare Policies

  • Landowners may purchase select herbicides at the 80% costshare to apply themselves.

  • Landowners may also hire a private contractor to apply the herbicides. See below for a list of local commercial applicators who have given the District Permission to disclose their phone numbers. 

  • Herbicide must be purchased at the District office and will be sold on a first come, first serve basis until stocks or funding are depleted

  • Products offered are HighNoon, DuraCor, and Escort XP herbicides.

Application Guidelines

  • Apply Escort XP at a 1 oz./acre rate. 

  • HighNoon or DuraCor may be tank mixed with Escort XP at a rate of 16 oz/acre for improved control.

  • Apply when whitetop plants are in the bud to blooming stages for the most effective control. Rosettes may also be treated in the early fall.

  • Use of a surfactant such as methylated seed oil or a nonionic surfactant is highly recommended.

  • Blue indicator die may also be used for spot treatments to avoid treating the same weeds multiple times.

  • Surfactants and dye may be purchased at the District office at full price.
