Not having any suitable photos to illustrate this week’s topic I decided to put in some shots from our garden here. Above: Evergreen barberry (Berberis x gladwyensis ‘William Penn’) as it appears today—large and beautiful; another evergreen barberry (Berberis x lologensis ‘Mystery Fire’, a brighter colour but not quite so large; and our white Camellia (C. japonica ‘Elegans Champagne’) grows in a container. Below: Camellia japonica ‘Tom Knudsen’; Grevillea banksia ‘Canberra Gem’ as it bloomed for its extended spring into early summer period last year; and the final shot part of the same plant showing the winter damage this year and with very few flowers. We shall prune it when the flowering (!) is complete.

Health Canada has found that glyphosate does not present risks of concern to human health or the environment when used according to label directions. Health Canada is granting continued registration of products containing glyphosate for sale and use in Canada. Products containing glyphosate are unlikely to affect your health. Dietary risks from food and water are not of concern. Non-occupational risks are not of concern. Non-occupational risks from by-stander dermal exposure are not of concern. Glyphosate products are not expected to pose risks of concern to the environment. Overall, there are currently no environmental incident reports involving glyphosate in Canada. Health Canada, as well as all other national regulatory agencies, have vindicated glyphosate. Health Canada’s primary objective in regulating pest control products is to protect Canadians’ health and their environment. Pest control products must be registered by Health Canada’s Pest Management Regulatory Agency (PMRA) before they can be imported, sold, or used in Canada. Pest control products must go through rigorous science-based assessments before being approved for sale in Canada. All registered pest control products must be re-evaluated by the PMRA on a cyclical basis to make sure they continue to meet modern health and environment safety standards and continue to have value.

In 2015, Health Canada’s Pest Management Regulatory Agency (PMRA) published the out-come of its extensive Re-Evaluation of Glyphosate for public comment, which concluded that the products containing Glyphosate do when used according to the revised product label directions. During this Re-Evaluation, the PMRA assessed the potential human health risk of Glyphosate from drinking water, food, occupational and by-stander exposure, as well as the environmental risk to non-target organisms.

Both the active ingredient and formulated products were included in the Re-Evaluation.

The Re-Evaluation was carried out based on available information provided by the manufacturer of the pest control product, as well as a large volume of published scientific literature, monitoring information ( for example, ground water and surface water ) and reviews conducted by other regulatory authorities.

The overall finding from the re-examination of Glyphosate is highlighted as follows -

Glyphosate is not genotoxic and is unlikely to pose a human cancer risk.

Dietary (food and drinking water) exposure associated with the use of Glyphosate is not expected to pose a risk of concern to human health.

Occupational and residential risks associated with the use of Glyphosate are not of concern, provided that updated label instructions are followed.

The environmental assessment concluded that spray buffer zones are necessary to mitigate potential risks to non-target species (for example, vegetation near treated areas, aquatic invertebrates and fish) from spray drift.

When used according to revised label directions, Glyphosate products are not expected to pose risks of concern to the environment.

All registered Glyphosate uses have value for weed control in agriculture and non-agricultural land management.

All comments received during the consultation process were taken into consideration.

Therefore, Health Canada’s Pest Management Regulatory Agency is granting continued registration of products containing Glyphosate with requirements of additional label updates to further protect human health and the environment.

To comply with this decision, the required label changes must be implemented on all product labels sold by registrants no later than 24 months after the publication date of the Re-Evaluation Decision.

Glyphosate is a broad-spectrum, non-selective herbicide. It controls many annual weeds, perennial weeds, woody brush and weedy trees.

It is registered for use on a wide variety of sites including terrestrial feed and food crops, terrestrial non-food, non-feed and fibre crops, and for non-agricultural, industrial and residential weed management for non-food sites, forests and woodlots, outdoor ornamentals and turf.

Glyphosate is present as the free acid or as a salt in formulated end use products.

Glyphosate products are formulated as solutions, pastes or tablets and can be applied using ground or aerial application equipment.

Other application techniques are also used to apply Glyphosate, such as with a wiper or wick applicator, cut stump or stem injection treatment.
