Nonselective herbicides have what broad action?

Nonselective herbicides have what broad action?

• A. Kills all plants
• B. Kills only grasses
• C. Kills only broadleaf plants
• D. Selective action depending on species

Answer: (A)

Nonselective herbicides are designed to affect a wide range of plants, not just one type. They target plant processes common to many species, so when they contact vegetation, they tend to kill both grasses and broadleaf plants rather than sparing one group. That makes them useful for clearing an area completely, such as before planting or when you want to remove all vegetation. In contrast, herbicides that spare either grasses or broadleaf plants are described as selective, which is why the other options describe targets that aren’t characteristic of nonselective products.
