03 – 2011

In our agri-food industry, we have a responsibility to produce safe food and insure public safety

and personal safety while achieving production efficiency. Scientific development during the past

several decades has allowed good progress on all fronts. In the past, pest control products were

mainly natural or organic and have almost always been very toxic and very persistent. The

introduction of 2,4-D in the 1940s signaled a change. It continues to be used. World wide, it has

been re-evaluated 17 times; each time passing tougher scrutiny. DDT was also first available for

use in the 1940s. It was safe for humans but was persistent in the environment so its use was

curtailed in Canada within about 20 years.


Concern for the environment and human health soon brought much more careful scrutiny of the

many new products that came to market. Public concern and strict regulation based on the full

body of evidence-based science, plus built in precautionary factors resulted in the development of

increasingly safer products and more precise application. Education programs and certification

for growers in Ontario and the development of Integrated Pest Management strategies has

allowed reduced use of pesticide and reduced risk of pest tolerance to specific pesticides.

Recently, new genetics have made some crops resistant to some pests or pesticides. This has

allowed further reduction of applied pesticide and created opportunity to use the safest product.

Science allowed these advances.


In general, the lawn care industry behaved differently than farmers. Farmers marketed their

produce. The lawn care industry aggressively marketed their services. More applications

produced more profit. Their cavalier attitude toward public concern about pesticide safety was

one factor that led to the “Cosmetic Pesticides Ban Act, 2008”.


That “Act” was also driven by eco-activist agendas. Through history there has always been some

resistance to science because science often does not support philosophical beliefs. However,

this movement really got underway during the DDT experience of the 1960s. Often these people

have been honest and their causes have been legitimate. However, as time wore on, emotion

and philosophy and marketability has driven causes. Selected pieces of science have been

“used” to support their positions. This is fraudulent use of science.


Following the Walkerton water quality experience, the eco-activist movement has regularly missused

the “precautionary principle” i to advance their causes. A full body of sound evidence-based

science has not been demanded by politicians as they considered the pesticide issue. Evidence

presented has gone unchallenged, as did the credentials of the presenters. The result is the

“Cosmetic Pesticide Ban Act, 2008”.


At a meeting of the Ontario Fruit and Vegetable Growers in January 2009, Gord Miller, Ontario’s

Environment Commissioner, was reported to say, “The decision to ban cosmetic use of pesticide

was not backed by science, making it a political decision – which politicians have the right to do.”

ii This lack of science gives cause for real concern as we look to the future. It encompasses

reduced science and transparency through the pesticide evaluation process. It (incorrectly)

seems to assume that old or natural pesticide is safe. The efficacy and cost of natural product

seems to be disregarded. Example: For weed control in turf, chelated iron is the best substitute

for 2-4,D. However, the data shows weed control is not good and the cost appears to be 3,500

times higher than 2,4-D.


The eco-activist anti-science, anti-business agenda will continue. On a day by day basis, modern

agriculture is portrayed as environmentally irresponsible and contributing to food and health risk

issues. Synthetic pesticide, no matter how safe, is referred to as poison on our food.

Science based food production is being challenged. Agriculture is under scrutiny. We cannot

count on support from government as municipally and provincially it appears they take positions

based on their perception of the public mood. Premier McGuinty indicates that the lawn care ban

is ‘just a first step’. iii


Ontario agriculture must respond in two ways:

1. Farmers themselves must police the industry to use responsible management of

soil, water and other resources. Sloppy management is not acceptable. Our track

record has been good with initiatives like the Grower Pesticide Safety Courses and

Environmental Farm Plans. We must continue with similar activities, and more

importantly, we must keep telling this story to the public.

2. Farmers must defend the science that supports high productivity of safe, high

quality food, farmers must aggressively tell their story directly to the public NOW!

Good face to face relationships are important. Communication must be accepted

as a cost of doing business.



The “Precautionary Principle” was intended (at the Rio Declaration) for use where science does

not exist. It currently is used by eco-activist groups to justify their position where science does

not support their philosophy.

– 1520. “


Two weeks before the last election, Premier McGuinty was on The Bill Carroll Show on

CFRB. On that show he’s reported to have said, when asked about the pesticide legislation, that

this is the first step. I guess there’s more to come. I do ask, when will the other shoe drop?” –
