What describes a broad-spectrum pesticide?

A broad-spectrum pesticide is defined as a pesticide that is effective against a wide variety of target species. This means that it is designed to control multiple types of pests, rather than being limited to just a few specific ones. Broad-spectrum pesticides are valuable in agriculture and pest control because they can address complex pest infestations where multiple species are present, providing a more comprehensive solution.

In contrast to the option that describes a pesticide effective only on specific pests, a broad-spectrum pesticide’s effectiveness across a variety of species makes it a versatile tool. Similarly, the option regarding localized use refers to application methods rather than the spectrum of pest control; broad-spectrum pesticides can be used over larger areas. Finally, while some broad-spectrum pesticides might be formulated with environmental considerations in mind, not all are inherently environmentally friendly, so this option does not accurately represent the defining feature of broad-spectrum pesticides.
