Human disease control
help protect us from allergens
pesticides to control threats posed to public
health and native species by pests and invasive
species has greatly improved our quality of
help ward off disease. In Canada, pests
such as mosquitoes and rats no longer pose the
disease threats of the past such as malaria,
yellow fever & typhus.
North American emergence of the West Nile Virus
and new cases of malaria, both transmitted via
mosquitoes reminds us that where possible, pesticides
can provide significant benefits in controlling
pests that threaten human health or the environment.
soil erosion and enhancing air quality
15 to 20 percent of the population has hay fever
- or allergic reactions to plant pollen, dust
and other airborne particles - and ragweed is
the major cause of the problem. Pollen grains
are minute and are thus easily airborne and
dispersed over long distances.
fever is most common among 24-to-44-year olds,
and the economic impact of their diminished
productivity is substantial. For many individuals,
high pollen counts trigger asthma attacks, and
may promote the development of the condition.
energy use and greenhouse gas emissions
well-maintained lawns will reduce surface temperatures
by 18 to 24 degrees Celsius in comparison to bare
soil, and 10 to 15 degrees Celsius in comparison
to natural vegetation or poorly managed grass.
lawns have the ability to trap and hold rainfall
better than most surfaces. The water you see
running down a street into the storm severs
generally is from driveways, sidewalks, and
other hard surfaces. A healthy lawn reduces
the amount of urban road wash and silt that
would otherwise end up in our streams and lakes.
well-kept, vigorously growing lawn absorbs hazardous
air pollutants such as carbon dioxide and
sulphur dioxide in the urban environment.
and trees are great air cleaners. If you
have ever walked or driven through an area with
no trees or grass, such as a construction site,
on a windy day, you have some idea of what it
would be like without a healthy green landscape.
Clouds of wind-blown dust make for uncomfortable
breathing, irritated eyes, and reduced visibility.
Grass slows the air, allowing dust particles
to settle on the leaves and eventually be washed
back onto the ground.
moderate cold temperatures, reduce heat loss and
build an insulating buffer of air around buildings.
Ornament plants also absorb heat and provide shade,
reducing solar radiation and reflection and unnecessary

of using pesticides
Pesticides help to limit the environmental and economic
damage that can be caused by insects, weeds and
plant diseases. Whether it is an insecticide for
controlling termites or fleas in your home, an herbicide
for ridding your lawn of undesirable weeds or a
fungicide that keeps plants alive during a disease
outbreak, pesticides are analogous to the medicines
we use to preserve our own health.
By using pesticides appropriately, municipalities
and homeowners provide the following benefits:
turf offers many benefits:
threats to human health;
our eco-systems from invasive species; and
the quality of our environment.
allergens and the likelihood of insect bites
dust and pollen from weeds and grasses; and
pollutants from the air and reducing noise in
busy urban centers.
also makes your life a bit quieter. It effectively
absorbs and deflects sound. When combined with
trees and other landscaping, grass can reduce
noise levels by 20 to 30 percent.
