IPM and pesticide monitoring
Integrated Pest Management (IPM) is based on conserving and enhancing naturally occurring limiting factors to contain plant pests and diseases below thresholds that cause economic damage.
IPM seeks maximum use of naturally occurring pest controls including weather, disease agents, predators, and parasites. In addition, IPM utilizes various biological, physical, and chemical control and habitat modification techniques.
Artificial controls are imposed only as required to keep a pest from surpassing intolerable population levels predetermined from accurate assessments of the pest damage potential and the ecological, sociological and economic costs of the control measures. The presence of a pest species does not necessarily justify action for its control, and in fact tolerable infestations may be desirable, providing food for beneficial insects, for example.
Integrated pest management (IPM) is based on several fundamental economic and ecological principles. First, from an economic point of view, scarce time and resources should not be devoted to the application of pesticides when pest populations are not likely to significantly damage crops. Pesticides sould not be used according to the calendar, with no reference to the real threat by pests. This means that much pesticide use constitutes a waste of resources.
Secondly, from an environmental point of view, indiscriminate pesticide use has led to the eradication of the natural predators of the pests, the development of pesticide resistant varieties of pests, and the spread of hazardous chemicals which threaten the health of both human beings and farm animals. Thus, IPM recognizes that pesticides should be used as little as possible, and only when measurements of insect populations indicate that pesticide intervention is both economically justified and the only viable method to control these pests.
