Weed Crisis Averted: CAPE Confirms Toxic Pesticides Not Needed; Petition proposes end date, permits
We, the Canadian Association of Physicians for the Environment (CAPE), have released a new report which refutes the myth that municipalities need to use toxic pesticides in parks and green spaces, if they hope to avoid a dandelion apocalypse. That has been a fear expressed by some municipalities, faced with the restrictions imposed by bans on the use of toxic pesticides on lawns and gardens, particularly in Manitoba and Alberta.
Such worries have proven groundless.
CAPE’s report is based on interviews with parks managers in six municipalities across Canada – London, Guelph, St. Catharines and Toronto in Ontario, Richmond (BC) and Cape Breton Regional Municipality (Nova Scotia). All of the selected cities are operating under either municipal or provincial restrictions on the use of toxic pesticides for lawns and/or gardens.
The study found that publicly acceptable levels of weed control can be achieved at a reasonable cost without the need for toxic pest control products. Weed program managers said they have adopted cultural practices to actively maintain turf health and to reduce or eliminate the need for pesticides. These practices include mowing, aerating, overseeding, fertilizing and top-dressing.
Concerns over soaring costs for labour and allowable products have also turned out to be unfounded. Program budgets are stable, according to those interviewed for the report. Under cosmetic pesticide bans, cities are not spending more than they previously did on weed control. Instead, they are spending their available resources differently, with a focus on turf maintenance and mechanical control. Under alternative approaches, permitted pesticide products are sparingly used for specialized purposes such as weed control between sidewalks blocks and paving stones.
Parks managers acknowledged the presence of some weeds, and reported that there are some public complaints (particularly about dandelions in the spring). But, they said, complaints have decreased significantly where pesticide restrictions have been in effect for a number of years. People do not expect all green spaces in the community to be totally weed-free. A majority of residents have come to accept the groomed (but not manicured) appearance of public green spaces.
In practice, program managers are able to maintain sports fields, high-use parks and other priority locations in well-groomed condition without resorting to the more toxic pesticides. And they find residents to be supportive of weed control methods that avoid exposing people to toxic pesticides. Public complaints are described as “minimal.”
Publication of the report is another step in CAPE’s efforts to support, encourage and strengthen bans on the use of toxic pesticides on lawns and gardens across Canada. In Manitoba, where a comprehensive pesticide ban was introduced in 2015, the Province has been considering revisions because of fears about costs, expressed by municipalities. In Alberta, where there are neither municipal by-laws nor a provincial law banning the use of toxic pesticides on lawns and gardens, municipalities have resisted even adopting corporate policies that would prohibit the use of toxic pesticides on city-owned properties. The study provides evidence, based in real-world experience, that anxieties about the cost, effectiveness and public acceptance of alternatives are unwarranted.
Indeed, in light of their success in implementing cultural practices to maintain healthy plants and turf, key informants in the study said they would not return to using the banned pesticides, even if they were allowed to do so. The toxic products are simply not needed, parks managers said

County, Azure Farms reach agreement on weed control
Sherman County, Ore., commissioners and Azure Farms agreed to a weed control plan that may settle a dispute that pitted the organic operation and its supporters against conventional wheat growers who don’t want weeds spreading into their crops.
The farm near Moro in the north-central part of the state agreed to control weeds, with “control” defined as “little or no noxious weed seed production that would affect neighboring fields” and spread by the wind. Conventional farmers are chiefly concerned about seeds from Rush Skeleton, Canada thistle, White top, Diffuse napweed and Morning Glory, or Bindweed.
Azure weed plan takes root
After hearing other comments similar to those expressed by Cranston, David Stelzer told the audience that he had authorized the social media campaign. He said, because he does not have a Facebook page, he did not understand the ramifications of his postings.
“I am sorry,” he said. “I do apologize for unleashing social media on this county, I didn’t want to vilify the county in any way.”
The Stelzer family, including David’s brother Nathan, farm manager, expressed surprise that so many people were upset about their production practices.
Nathan said two big projects in Dufur, where Azure is headquartered, had kept the company too busy to be diligent about stewardship of the land in Moro, where there is a large distribution center for organic products.
He told the audience that his son, Nathaniel, was newly married and he and his wife, Sarah, would be living on the Moro property to concentrate on weed control. He said Azure had also hired a consultant to work on a biological program to address the problem.
“We have every intention of living peaceably with our neighbors and do not want to do them any harm,” said Nathan.
His son also spoke to the crowd.
“Thank you for coming and voicing your opinions. We didn’t realize it was an issue because we knew you sprayed. It wasn’t until this all came out that we realized we’d hurt you and we’re sorry,” said Nathaniel.
The Stelzers agreed to work with Rod Asher, supervisor of the weed district, and other Sherman officials to develop a new weed control plan that would not require chemicals, which they strongly opposed.
“It’s a long-term thing, organic methods are slow,” said David. “Nothing works quickly in nature, it takes time.”
He said the demand for organic foods was growing and Azure did not want to lose the market they had built over the years by spraying weeds.
Azure was established in Dufur in 1989 and expanded its operation to Moro in 1999.
The Stelzers proposed a combination of tillage, mowing and organic products to get rid of weeds.
Coexistence: Azure Standard, Oregon Farmers, Weeds, and Herbicides
Sherman County may order owners of a 2,000-acre organic farm to spray noxious weeds or face a possible quarantine.
Local wheat farmers say weeds spreading from Azure Farms, on the outskirts of Moro in north central Oregon, cost them money in the form of additional herbicide control. Most critically, growers of certified wheat seed say their crops will be worthless if contaminated by Rush Skeleton Weed, Canada Thistle, Morning Glory and White Top spreading from the farm.
Spraying the weeds with Milestone or other herbicides, however, would cause the farm to lose organic certification for three years. Azure Standard, which operates Azure Farms, is a major distributor of organic products.
Sherman County gave the farm until May 22 to respond with a weed management plan. If not, the county will ask the Oregon Department of Agriculture to quarantine the farm.
The issue has blown up on social media.
The manager of Azure Farms, Nathan Stelzer, urged supporters to “Overwhelm the Sherman County representatives with your voice.” A video posted on the farm website called for people to express their outrage reportedly has resulted in hundreds of phone calls and thousands of emails to county officials.
The issue may come to a head Wednesday when the county’s Board of Commissioners takes up the issue. The county is expecting such a crowd that it moved the session from the courthouse to the Sherman County School gym, 65912 High School Loop, Moro, at 4 p.m.
