Use of Pesticides for Parks Maintenance

Council has requested a report. on the use of pesticides by
the Parks Department and, although I do not claim to be an expert
in horticulture or chemistry, I will attempt to set out my general
views on the consequences of eliminating the use of all pesticides.

To begin, I would like to point out that the use of chemicals
in City parks can be divided into three different categories as
follows: for cosmetic purposes, to eliminate nuisances, and for
the preservation of City facilities. 12 will discuss each of these
categories separately.

Cosmetic.

Under this heading would come the use of herbicides for

pose of controlling weeds in flowerbeds or in controlling
the growth of vegetation close to buildings or playground equipment.
Herbicides used in this category include Grammoxone, Round up, and
Casaron. Elimination of the use of these chemicals would not
‘result in any serious nuisance or damage to property but will
result in unsightly conditions around the City unless alternative
measures aré adopted:

Alternative wavs of dealing with the weed problems in this
category would be hand picking of weeds in flowerbeds or the use
of weed eaters around buildi tree trunks, and
ment. i

approximately $30,000.
Nuisance

Pesticides in this category are used to control problems
which create a nuisance for others. Examples would be control of
WaSpS or control of thistles along the dyke which blow seeds onto
farm land making it Léss procuctive. Chemicals which falr- tints
this category wold includée”"Hyvar; Round up, Raid.
