The Fraser Valley Regional District (FVRD) is partnering with the Fraser Valley Invasive Species Society (FVISS) on the Knot On My Property cost-share pilot program to encourage residents to control knotweed growing on private property. 

Program Details:

• Participating landowners can have 50% of the treatment costs covered (up to a maximum of $500)
• Funding is allocated on a first-come first-served basis. The budget is limited and dispersal may vary year-to-year based on the popularity of the program.

If this pilot program is extended, landowners who participated will be given priority access to participate in subsequent years.

Rebates will not be given to landowners who treat knotweed themselves, or who use a non-approved contractor.  

As this is a new pilot still in a trial stage, the FVRD reserves the right to update or change this program in subsequent years as required and as funds allow.

Treatment of knotweed usually takes several years until the infestation is considered eradicated.  Follow-up treatments will likely be required.  Property owners should be prepared to continue treatments annually until the plant stops returning.

Approved Contractors

Approved contractors must have valid Pesticide Applicator Certificates and have experience controlling knotweed according to the BC Integrated Pest Management Act and the herbicide product label instructions. Care must be taken to minimize impact to surrounding area.

Approved contractors must conduct knotweed treatment work according to known best management practices (BMP). Current BMP indicate that chemical control with a systemic herbicide is the most effective method for treating knotweed. Manual or mechanical methods are generally ineffective due to knotweed’s extensive rhizome system and should only be employed in specific circumstances and with extreme caution.
