Industry Insights

The general public may have questions about vegetation management and its potential impact on pollinators. It can be difficult to answer questions if you are approached unexpectedly. To help vegetation managers and applicators manage these inquiries, here are a few key messages to convey if approached by a concerned citizen: 
 

Why does vegetation need to be managed?

Vegetation management is critical and necessary to control unwanted vegetation that may create a safety, health, occupational or environmental hazard. The safest and most cost-effective long-term solution for controlling vegetation is an integrated vegetation management program that uses both mechanical and herbicide control strategies.
 

How is vegetation managed?

Mowing and trimming are important parts of any vegetation management program; however, mechanical control can reduce pollinator habitat, distribute weed seeds and cause some plant species to re-sprout rapidly resulting in increased stand.
Selective application of herbicides controls specific weeds or groups of weeds, reducing damage to non-target plants. It allows desirable species to flourish, increasing biodiversity. Furthermore, it is less disruptive to the landscape and controls the entire plant, so crews only need to visit the site once every two to four years.
 

Do herbicides affect pollinators?

Herbicides used by vegetation managers should not be confused with insecticides. While insecticides target the nervous system of an insect, herbicides target a specific pathway in plants. These target sites do not exist in pollinators, including bees.
 

How are herbicides regulated and registered in Canada?

All pesticides undergo a risk assessment by Health Canada’s Pest Management Regulatory Agency (PMRA) to determine potential toxicity to bees. Each product is assessed for both oral and contact toxicity.
 

Pollinators and Corteva Agriscience™ herbicides:

None of Corteva Agriscience™ herbicides used in vegetation management have been found to be toxic to bees and other pollinators. In fact, they are categorized as “practically non-toxic”, which is the safest possible category assigned by the PMRA. Corteva Agriscience Industrial Vegetation Management herbicides, when used according to the label, only affect the plants they are designed to control.
 

Ways applicators can minimize potential pollinator exposure:

Applicators can minimize potential pollinator exposure by:
• reading and follow label directions,
• using selective herbicides,
• conducting an inventory of existing vegetation,
• adjusting application timing,
• avoiding application when weather conditions increase drift.
