IPM: Strategy to avoid or prevent pest damage with minimum adverse impact to human health, environment and non‐target organisms
Focuses on tactics to avoid or minimize damage before it occurs, integrating previous knowledgewith pest monitoring information and the expertise of the practitioner…
• Ecosystem science, community ecology, population and organismal biology and ecology, genetics…
• Of plants, herbivores and their predators, opportunistic‐ and invasive species, etc.
• General principles apply to all species including ‘noxious’ common pests and pathogens
• Used in developing appropriate pest/disease/weed management tools
Integrated Pest Management, a Science Based Approach
Key scientific concepts in IPM• Crop yields are often limited by herbivores, plant pathogens, weeds…
• Most plants tolerate a minimum level of injury before damage occurs; this level varies greatly
• Populations are affected by environmental conditions and by the populations of other species, natural enemies and competitors
• Impact of mortality factors often varies with pest/pathogen population density (# per area)
• Pesticides are essential management tools and should be used to prevent or minimize damage

Treatment at low pest density is more effective and prevents damage
Disease Epidemiology
• Types of epidemics: monocyclic and polycyclic
• Monocyclic: Polycyclic:
x = QRt x = X0ert
• Q = initial inoculum, R = rate of infection, t = time
• X0= initial disease incidence, r = rate of infection, t = time
