What is a common practice in an IPM approach regarding pesticide use?

In Integrated Pest Management (IPM), the emphasis is on sustainable and environmentally sensitive pest control methods. A core principle of this approach is to use pesticides judiciously, which means they are applied sparingly and only when necessary. This practice helps in minimizing the potential negative impacts on non-target organisms, including beneficial insects, and reduces the risk of pesticide resistance developing among pest populations.

The strategy involves a thorough assessment of pest situations, integrating various control methods such as biological control, cultural practices, and mechanical controls before considering chemical interventions. By using pesticides at critical points when pest levels exceed economically significant thresholds, practitioners can manage pests effectively while prioritizing environmental health and safety.

In contrast, using only organic pesticides without assessing their effectiveness or banning all chemical pesticides outright does not align with the IPM philosophy, as it may overlook effective solutions. Additionally, routinely applying pesticides every time a pest is identified can lead to overuse, increased resistance, and harm to beneficial organisms. Therefore, the correct practice under IPM is to carefully assess and use pesticides only as needed, aligning with the overall goal of promoting sustainable agriculture.
