SSC Selection Post 2022 PYQ — Question 47

The correct answer is option 4 i.e. Rotenone.

 

Rotenone is a natural pesticide derived from the roots of certain tropical plants like Derris and Lonchocarpus. It has been traditionally used by indigenous communities to stun fish in water bodies. As a pesticide, rotenone is effective against a wide range of insect pests such as aphids, beetles, and caterpillars. It works by interfering with the cellular respiration of insects, leading to their death. Although natural, rotenone can be toxic to fish and humans in high doses, so it must be used with caution. It is biodegradable and breaks down quickly, making it an eco-friendly alternative to synthetic pesticides when used properly.
