Chemical Application Information

Why you're seeing our sign

Vertex Grounds Management posts a notification sign whenever we apply a pesticide or fertilizer to turf or landscaping in an area the public can access — lawns, boulevards, common areas, and commercial or municipal grounds. The sign shows the date of application. We leave signs in place for at least 48 hours after the application, as required in Alberta.

What we apply

Depending on the property and the season, our programs may include:

• Selective broadleaf herbicides — used to control weeds like dandelion and clover in turf without harming the grass. Typical active ingredients: 2,4-D, mecoprop-P, and dicamba.
• Iron-based herbicides (chelated iron, FeHEDTA) — a reduced-risk option we use where suitable, especially near sensitive areas.
• Non-selective spot treatments (e.g. glyphosate) — limited to cracks, gravel, fence lines, and hard surfaces. We do not blanket-spray lawns with non-selective products.
• Turf fertilizers — granular or liquid nutrients. Fertilizer is not a pesticide, but we sign and treat it with the same care.

Every pest control product we use is registered by Health Canada's Pest Management Regulatory Agency (PMRA) and carries a Pest Control Product (PCP) registration number. The product name, PCP number, label, and safety data sheet for anything applied at a specific location are available on request — call or email us with the address and the date shown on the sign.

How we apply it

• Applications are performed by, or under the supervision of, applicators holding a valid Alberta pesticide applicator certificate in the relevant category, and our company holds the required pesticide service registration.
• We follow the product label — it's the law. Label rates, restrictions, and re-entry directions are never exceeded.
• Weather rules: we don't spray in winds above label limits, before expected rain, or in heat that promotes drift or volatilization.
• Spot treatment first: we scout and treat weeds where they grow rather than blanket-spraying, and we skip applications where they aren't needed.
• Buffers: we maintain setbacks from vegetable gardens, ponds and waterways, playgrounds, and marked sensitive areas.

After an application: what you should do

• Keep people and pets off the treated area until it is fully dry, or longer if the sign or label says so.
• Remove or wash children's toys, pet bowls, and chew items that were on the lawn during application.
• If skin contacts wet product, wash with soap and water. Rinse pet paws with water.
• If anyone experiences symptoms they believe are related to a pesticide, contact the Poison & Drug Information Service (PADIS) at 1-800-332-1414 (Alberta, 24/7) or seek medical attention, and call us so we can provide the product label to you or your care provider.
• Waiting to harvest from a vegetable garden near a treated area? Call us — we'll check the label's specific guidance for you.

The product label is the governing document for any specific application. If anything here conflicts with a product label or a direction from a regulator, the label and the regulator win.
