What is a primary characteristic of pyrethrum as a pesticide?

• A. It contains synthetic chemicals.
• B. It is derived from chrysanthemum flowers.
• C. It is used exclusively on crops.
• D. It requires high amounts of application.

Answer: (B)

Pyrethrum is primarily characterized by its derivation from the flowers of the chrysanthemum plant. This natural origin is significant because it highlights pyrethrum's status as a biopesticide, making it distinct from synthetic pesticides that contain man-made chemicals. The active compounds in pyrethrum, specifically pyrethrins, are known for their effectiveness in disrupting the nervous system of insects, which is critical for pest control. The natural composition of pyrethrum is favored in many organic farming practices due to its relatively low toxicity levels to humans and pets compared to synthetic pesticides. Understanding this natural source aids in recognizing the ecological benefits and the appeal of pyrethrum as a sustainable pest management option.
