On Campus - Harmful fungicide and pesticides are not used on campus and haven't been for more than a decade. In 2009, grounds phased out herbicides for weed control on hard surface (between sidewalk slabs). There is a plan to rely on natural remedies in a conversion to all environmental products.
The Ministry of Health and Ministry of Environment have requested that infestations that may harm the public or environment are controllable with chemicals. The process for chemical use is lengthy and requires approval from the government prior to application.
At the time of certification, producers must be complying with “national and international legislation regarding the use of pesticides, handling pesticides, the protection of natural waters, virgin forests and other ecosystems of high ecological value, erosion and water management.” They are banned from using several classes of pesticides that are considered particularly dangerous.
