What is a potential outcome of improper pesticide application?

The potential outcome of improper pesticide application leading to increased pest resistance is a significant concern in pest management. When pesticides are not applied correctly—whether through incorrect timing, dosage, or method—certain pests may survive the treatment. These surviving pests are often those that possess or develop resistance to the pesticide being used. Over time, as these resistant pests reproduce, they can lead to a population that is increasingly harder to control, necessitating the use of more potent or multiple pesticides. This can create a cycle of reliance on stronger chemicals and further environmental and economic repercussions.

In contrast, higher crop yields would typically be a positive outcome of proper pesticide use, not a consequence of improper application. Similarly, lower pesticide costs are unlikely to arise from flawed application practices; often, improper use can lead to increased expenses due to the need for additional treatments or more expensive alternatives to combat resistant pests. Therefore, the most accurate answer reflects the real and concerning process of increased pest resistance caused by improper pesticide handling.
