It is possible to obtain a two-pass shock treatment for major plantain using a highly effective product at additional cost.

How does weed control work?

For weed control, technicians water weeds in a localized manner. They only water weeds that have emerged from the soil. If you notice weeds appearing after our visit, it’s because the weed had not yet emerged above ground. A second treatment will be carried out on the next pass to deal with these new shoots.

How long does it take to control weeds?

In unregulated cities, the synthetic herbicide will take effect on weeds in 3 to 5 weeks. The stems will bend, twist and stop growing.
In regulated cities, the results of applying organic herbicide will take between 4 days and two weeks, but you’ll see the first signs within a few hours as the weeds change color to a brownish hue. However, it will take several treatments to get rid of the weeds.

What types of herbicides are used?

In cities not regulated in terms of pesticides, technicians apply a synthetic herbicide to control broadleaf weeds. Effectiveness varies according to temperature and humidity. Ambient temperatures allow the herbicide to be better absorbed by plants.

In pesticide-regulated cities, technicians apply a selective biological herbicide for broadleaf weeds. The product resists rain as early as 3 hours after application, and is safe to use once dry.

A plant under stress is more difficult to control, which is why we don’t apply herbicides during periods of extreme heat and drought.
For your safety and the best effectiveness of the products, please wait 24 hours before mowing, watering or making any movement on the lawn.

Why doesn’t herbicide kill the lawn?

The metabolisms of grasses and weeds are different, and plants metabolize herbicides in different ways. However, if a large dose of herbicide is applied, it can indeed kill the lawn.

Does cVert do fertilization and weed control when it rains?

cVert can apply fertilizer even when it’s raining, but can’t apply pesticides when there’s more than a millimetre of water in the day. If a pesticide is applied during the rain, it will evaporate because the plant will not have had time to absorb the product.
