• B. Herbicide that kills broadleaf weeds
• C. Plant insecticide non-poisonous to man
• D. Growth stimulant for ornamentals

Answer: (D)

Rotenone is best described as a plant-derived insecticide. It comes from the roots of certain tropical plants and has been used to control insect pests. Its mode of action targets insects by disrupting cellular respiration, leading to energy failure and death. It is not a fungicide or a herbicide, nor does it act as a growth stimulant. Because rotenone can be harmful to non-target organisms, including humans and aquatic life, it should be handled with care and used only according to label directions.
