Which is a consequence of pesticide misuse?

Increased pest resistance results from pesticide misuse because when pesticides are applied improperly, they can kill susceptible pests while leaving behind those that have developed resistance. This selective pressure leads to a population of pests that are increasingly resilient to the chemicals used against them. Over time, this can cause the effectiveness of the pesticide to diminish, requiring higher doses or alternative chemicals to manage those pests, which can further exacerbate the issue. This cycle not only makes pest management more challenging but can also result in higher costs and potential environmental impacts.

In contrast, improved crop yields and enhanced soil health are typically associated with responsible and integrated pest management practices, while reduced operational costs are generally more achievable through effective pest control strategies rather than misuse.
