IPM

Definition

Integrated Pest Management; a decision-making framework for controlling pest populations that combines multiple tactics—biological control, habitat manipulation, cultural practices, resistant varieties, and targeted chemical applications—applied in a coordinated, knowledge-based manner to minimize economic, health, and environmental risks. IPM emphasizes monitoring pest densities and action thresholds rather than calendar-based prophylactic treatments.

Etymology

Acronym from "integrated pest management," a term coined in the 1960s–1970s to describe ecologically informed pest control strategies that moved beyond reliance on broad-spectrum insecticides.

Example

A vineyard IPM program for grape berry moth (Paralobesia viteana) might combine pheromone mating disruption, timed insecticide applications based on degree-day models and pheromone trap catches, and conservation of parasitoid wasps by avoiding broad-spectrum sprays during peak parasitoid activity.

Usage Notes

IPM is sometimes misused as a marketing term for any reduced-pesticide approach; technically it requires systematic monitoring, multiple compatible tactics, and decision rules tied to pest density. Contrasts with calendar spraying (fixed schedule regardless of pest pressure) and with organic production (which restricts but does not necessarily integrate tactics). The abbreviation is typically used as a mass noun ("practicing IPM") rather than countable ("an IPM").
