Which type of pesticide can affect a wide range of species, including fungicides and herbicides?

A nonselective pesticide is designed to affect a wide range of organisms, including various plants, insects, and fungi. This broad-spectrum approach means that nonselective pesticides can eliminate unwanted species across different categories, making them effective in situations where complete control over all plant growth or pest populations is necessary.

For instance, nonselective herbicides will target all types of vegetation, regardless of their desired or undesired status in the environment. This can include both weeds and desirable plants, highlighting the clear impact of these pesticides on a wide array of species.

In contrast, selective pesticides specifically target certain pests or plants while leaving others unharmed, which emphasizes a targeted control approach rather than a broad, encompassing method. Herbicides and insecticides, while crucial in pest control, generally fall within the selective category unless specified as nonselective. Therefore, when considering the range and impact of a pesticide, nonselective options stand out for their capacity to impact multiple species simultaneously.
