OP-9: Integrated Pest Management

An Integrated Pest Management (IPM) Plan has been in place at Western since 1992. Harmful fungicide and pesticides are not used on campus and have not been used for more than a decade. As of April 30, 2009, a new piece of legislation put forth by Western has forbidden the University from spraying unless it is a matter of high importance. The same year, Western Grounds phased out herbicides for weed control on hard surfaces (between sidewalk slabs). Currently, Western relies on natural remedies in a conversion to all environmental products. The Ministry of Health and Ministry of Environment has requested that infestations that may harm the public or environment are to be controlled with chemicals. However, the process for chemical use is lengthy and requires approval from the government prior to application; therefore, Western tries to avoid this practice. In addition, all gardens around campus are monitored under an IPM. Gardens that needed to be sprayed every 7 to 10 days have been removed. Western also plant trees that are thought not to cause problems. Specifically, Western has been buying black spot tolerant trees while making sure that they are being planted correctly, trimmed, and established properly so that little or no maintenance is needed. Another practice started by Western to prevent pests includes the removal of any plants which are susceptible to infestations. Any tree or shrub that is being considered for planting needs to meet the following criteria: - Have a long life expectancy - Come from a disease-free stock - Insect and disease resistant - Not an alternative host to a secondary disease
