Whitetop 80% Costshare Program

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

Costshare Policies

  • The costshare is on chemical only. 

  • Landowners must apply the chemicals themselves or hire a private contractor to do so. Below is a list of private contractors who have given the District permission to disclose their contact information.  

  • Chemical will be sold on a first come, first serve basis until stocks or funding are depleted

  • $1,000 limit per landowner.

  • Products offered are Escort XP or Telar XP dry granular herbicides and may be purchased at the District office.

Application Guidelines

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

  • Apply Escort or Telar 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 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.
