Please note, all herbicide application schedules are subject to change due to weather and programmed activities. 

Integrated Pest Management Strategy

According to the EPA, Integrated Pest Management (IPM) is the coordinated use of pest and environmental information with available pest control methods to prevent unacceptable levels of pest damage by the most economical means and with the least possible hazard to people, property, and the environment. The IPM strategy employs four common sense approaches to effectively manage the pests. These are:

  1. Thresholds for action
  2. ID and monitor the pests
  3. Prevention
  4. Control

The City assumes that all pesticides are potentially hazardous to human and environmental health. Therefore, reasonable non-pesticide alternatives shall be given preference over chemical controls by following the IPM procedure. City staff will evaluate alternatives to chemical treatment including the cost-effectiveness of the treatments.

Sites will be managed for weed or pest control by the following IPM procedures:

  1. Prevention: This is the most effective pest management strategy. By reducing the capacity of the ecosystem to support the target weed or pest populations through design and appropriate management, the opportunities for weed and pest establishment can be reduced or eliminated.
  2. Cultural: Cultural control is the use of management activities that prevent weeds and pests from developing due to the enhancement of desired conditions.
  3. Mechanical: Mechanical control is accomplished by using physical methods or mechanical equipment to control weeds and pests. Rough mowing of sites is the most prevalent.
  4. Biological: Biological controls include the introduction or enhancements of natural enemy populations to target weeds or pests.
  5. Chemical: Reasonable non-pesticide alternatives shall be given preference over chemical controls. Organic fungicides, plant growth regulators and insect pheromones are a few that are suggested. When chemical control of weeds or pests is necessary non-restricted use pesticides are suggested. No restricted use pesticides will be used in park landscapes.
