Clear Evidence: Neonics are undermining Essential Ecosystems

 Prepared by Kim Perrotta, MHSc, Executive Director, CAPE

Governments around the world must ban neonic pesticides without delay.  This is the message of the Task Force on Systemic Pesticides (TFSP) which released the second edition of the report, Worldwide Integrated Assessment of the Effects of Systemic Pesticides on Biodiversity and Ecosystems in mid-September.

The new report, which captures more than 500 scientific studies published since the first TFSP report was published in 2014, finds deeper and broader evidence of harm to ecoystems around the world due to neonic pesticides  It reinforces the conclusions of the earlier report: neonics, and the closely related pesticide fipronil, represent a major threat to biodiversity and ecosystem services.

Neonic pesticides are systemic pesticides that become absorbed into all of the tissues of a plant; the stem, leaves, flowers, and pollen.  Introduced in the early 1990s, neonics are the most widely used insecticides in the world today.  The new TFSP report confirms that chronic exposure to very low levels of neonic pesticides increases the death rates of living organisms.

The report documents a broad array of harmful impacts on bees including reduced rates of reproduction and bee colony growth.  It provides greater evidence that systemic pesticides harm a number of beneficial animals including worms that help recycle nutrients in the soil, aquatic insects that recycle nutrients in water systems, insects that prey on crop pests, insects that pollinate plants, common birds, and bats.  In other words, these pesticides are undermining the ecosystems upon which all life is dependent.

Eight different neonic products are registered for use in Canada.  In November 2016, Health Canada’s Pest Management Regulatory Agency (PMRA) proposed phasing out the use of one of the eight – imacloprid – over a three to five year period.  It has also initiated special reviews on two of the other neonics that are widely used in agriculture – clothianidin and thiamethoxam.

The European Union imposed a moratorium on several neonic pesticides in 2013. In July 2015, Ontario became the first jurisdiction in North America to limit the use of neonics for agricultural purposes.   This year, France passed a new law to ban all agricultural uses of neonic pesticides starting in September 2018.  Let the Federal Minister of Health know that she should accelerate the phase-out of imacloprid and all other neonic pesticides that are registered for use in Canada at: Ginette.PetitpasTaylor@parl.gc.ca.

Federal Agency Failing to Protect Canadians from Pesticides

Federal Commissioner of the Environment and Sustainable Development, Julie Gelfand, released a new report on pesticide safety this week.  It audits the processes applied by Health Canada’s Pest Management Regulatory Agency (PMRA) to the regulation of pesticides in this county.  It identifies a number of significant failings, which suggests that the PMRA is currently failing to protect Canadians and the environment from chemical pesticides.   

The Commissioner reports that the PMRA continues to make heavy use of ‘conditional registrations’ that allow companies to put their pesticides on the market before they have submitted all of the data and studies to the PMRA.   The PMRA is supposed to be reviewing the evidence submitted by companies to ensure that their products do not present “an unacceptable risk to human health or the environment”. Some of these conditional registrations have been in place for up to 20 years.

The Commissioner found that 80 of the 7,000 pest control products on the market today have been conditionally registered; 29 for more than 5 years and nine for more than 10 years.  Thirty-six of these 80 pesticides are neonicotinoid pesticides (or neonics). This is the class of pesticides that been strongly linked to the death of bees and the collapse of bee colonies in Canada.  They have also been strongly associated with harmful impacts on a wide variety of animals.  After reviewing more than 1000 peer reviewed scientific articles, the international Task Force on Systemic Pesticides concluded that neonics are likely to produce major adverse effects on ecosystem services, such as pollination, that are vital to food security.

The Commissioner’s report also found that the PMRA:

  • Has been moving too slowly when re-evaluating pesticides that have been on the market for more than 15 years; 
  • Has not been assessing the cumulative health effects of pesticides in all of the situations where it should;
  • Has not applied the 10-fold safety factor required to protect children and infants from pesticides in most situations where it should;
  • Has not been conducting special reviews promptly for pesticides banned by countries that are members of the Organisation for Economic Co-operation and Development (OECD) as it should; and
  • Has not moved quickly to cancel registrations for some pesticides when reviews demonstrate that they do pose “unacceptable risks” to human health or the environment.
