Ragweed

Ragweed is a weed that can be found from May to October. It starts to flower in mid-July, releasing fine dust-like pollen into the air. This dust causes allergic reactions in sensitive individuals.

Ragweed pollen is the main cause of the seasonal rhinitis that affects one out of every seven Quebecers.

Even though Pincourt doesn’t have any by-laws on ragweed at this time, a major awareness campaign is conducted every summer by Green Line personnel.

Among other things, they conduct foot patrols to look for ragweed. Whenever they spot ragweed, they leave an informative door hanger sign at the address in question.

The town’s inspector-technician can also leave notices at homes where ragweed has been found.

Health and Wellness Portal: Recognizing and controlling ragweed

  • Ragweed Operation

    On May 4, 2018, the Town of Pincourt received $32,910 in financial assistance from the Government of Quebec for the preventive fight against ragweed. This project is part of the Stratégie québécoise de réduction de l'herbe à poux et des autres pollens allergènes, a program funded by the Fonds vert under the Plan d’action 2013-2020 sur les changements climatiques. 

    This project has two components: awareness and product application.

    Awareness

    A prevention and awareness campaign was launched in 2018 among the citizens and students of the four schools in the territory, namely Edgewater, Notre-Dame-de-Lorette, St-Patrick, and Chêne-Bleu.

    Application of a product

    Groupe Arbo-Ressources sprays a product on undesirable plants. It is a saline solution that is safe for the environment and has a low impact on the environment.

    Applying the product once a year is enough to control ragweed. 

    Following application of the product, ragweed plants wilt and dry out completely within a few days. 

  • Minimizing the effects of ragweed

    The best way to minimize the adverse effects of ragweed is to limit the quantity in the surrounding environment.

    Pulling up or mowing ragweed

    • Pull out or mow any ragweed on your property before it releases its pollen (mid-July and mid-August).
    • Use your hands or a garden weeder to pull it up.
    • Throw out any pulled-up plants or cuttings with your garbage.

    Prevent ragweed from growing back

    • Use mulch or ground-cover plants in areas where there is no grass.
    • Improve the quality of your soil with humus, compost or fertilizer.
    • Sew grass or clover after pulling out ragweed.
    • Inspect your property regularly.
    • Keep your lawn dense and healthy to prevent ragweed seeds from germinating.
