Is it advisable to apply chemical controls when pests are present in minor quantities?

The most suitable approach to pest management is to wait for threshold numbers before applying chemical controls. This strategy is based on the concept of integrated pest management (IPM), which emphasizes the importance of understanding pest populations and their potential impact on crops or environments. Threshold numbers are defined as the pest population level at which it becomes economically viable or necessary to take action, thus minimizing unnecessary pesticide use and avoiding harm to beneficial organisms.

Applying treatments when pests are present in minor quantities can lead to several negative consequences, such as environmental impact, development of pesticide resistance, and harm to non-target species, including beneficial insects and wildlife. By monitoring pest populations and applying controls only when thresholds are exceeded, pest management can be more efficient and sustainable. This approach helps maintain ecological balance and supports long-term agricultural health.
