The modern method of controlling pests on crops that seeks to reduce but not eliminate pest populations is called Integrated Pest Management (IPM).

Here's why:

* Integrated: IPM involves combining various pest control methods, such as biological control, cultural practices, and chemical pesticides.

* Pest Management: The focus is on managing pest populations, not eliminating them entirely.

* Reduce, not Eliminate: IPM aims to reduce pest populations to a level where they no longer cause significant damage to crops.

IPM is considered a more sustainable approach to pest control as it minimizes the use of harmful pesticides and promotes a healthy ecosystem for both crops and beneficial organisms.
