2. To control insect pests

3. To enhance soil fertility

4. To treat diseases in humans

The correct answer is: To control insect pests

The primary use of insecticides is to control insect pests. Insecticides are specifically formulated chemical agents designed to kill, repel, or disrupt the life cycle of insects that can cause damage to crops, spread diseases, or infest structures. By targeting harmful insect populations, these substances help in protecting agricultural produce, ensuring food security, and maintaining the integrity of buildings against pest infestations. While promoting plant growth, enhancing soil fertility, and treating human diseases are all important aspects of agricultural and health practices, they do not fall within the main function of insecticides. These substances are not intended to support plant health directly, nor do they contribute to soil nutrients; instead, their sole purpose is pest control. Understanding the role of insecticides is crucial for effective pest management strategies in both agricultural and urban environments.
