Weed of the Week

Ih balsam impatiens glandulifera 01

Himalayan Balsam

Himalayan balsam is a summer annual of riparian areas which reproduces by seed only. Native to the western Himalayas, it was introduced to Kew Gardens in the early 1800s.

By the 1900s, it was already common in south-west Germany and spreading via the Rhine River, and throughout Scandinavian countries by the mid-1900s. Today, it is widely known as an invasive alien in temperate areas of Europe, Asia, North America and New Zealand.


About the Weed of the Week Series

This awareness series is brought to you by the Ag Services team. Our mission is to protect the integrity of our local ecosystem by empowering residents with the knowledge to combat invasive species.

Road Allowance Vegetation Management

From June to October, Ag Services crews apply herbicides along MD-owned road allowances to eradicate prohibited noxious weeds, noxious weeds and woody species. We target different parts of the MD each season depending on where problem vegetation may exist.

Weed Control Act

This provincial act outlines noxious or prohibited noxious weeds that present significant economic, social or ecological risks.

Opt Out of Vegetation Management

To opt out of the Roadside Herbicide Application Program, you must notify the MD before May 31 of each growing season. In doing so, you assume responsibility for control of noxious/prohibited noxious weeds and woody species on your road allowances.

Weed Control Partnership Program

The MD is pleased to partner with landholders on weed control measures. This partnership includes no-cost loans of herbicide application equipment (trailer sprayer, ATV sprayers and hand-held sprayers), plus rebates to landowners who destroy prohibited noxious weeds and control noxious weeds and on their lands.

We grant rebates of $20.00/acre to landholders who destroy prohibited noxious weeds and the control of noxious weeds on permanent cover land such as pastures, rangeland and fencelines. All prohibited noxious and noxious weeds are included.

Weed Control Through Rural Mowing

Rural mowing is a part of the MD's integrated weed management plan. These mowing activities keep roadside vegetation short to improve visibility and to ensure proper drainage. Mowing widths may vary from the edge of the road and depend on slope, obstructions and wet areas.

  • Range roads and township roads are mowed twice per year, between May and September
  • Rural hamlets are mowed a minimum of once per year, potentially twice depending on weather
