​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 Milestone and DuraCor herbicides and may be purchased at the District office.

​

Application Guidelines

• Apply Milestone at a rate of 6 oz./acre.

• Apply DuraCor at a rate of 16 oz/acre.

• Milestone is most effective when applied in the early fall when russian knapweed is approaching dormancy.

• DuraCor may be applied to russian knapweed at any growth stage for effective control. 

• 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.
