Which type of pesticide is derived from natural plant chemicals?

The correct answer is botanical pesticides because they are specifically derived from natural plant chemicals. These pesticides utilize compounds found in plants that have insecticidal or fungicidal properties. They can offer a more environmentally friendly option for pest control since they are often biodegradable and can be less harmful to non-target organisms. Botanicals are typically used in organic farming and are valued for their relatively lower toxicity compared to synthetic alternatives, appealing to consumers looking for sustainable pest management solutions.

Synthetic pesticides, on the other hand, are man-made chemical compounds designed to control pests but do not derive from natural plant sources. Biological pesticides encompass a broader category that includes organisms or substances derived from living organisms, but not exclusively from plants. Extended-use pesticides generally refer to products that can remain effective for longer periods once applied, which does not relate to their origin from natural plant chemicals.
