Herbicides are chemicals used for killing weeds and unwanted plants that compete for nutrition with crops. Considered as pesticides, they inhibit the growth of weeds to prevent them from occupying the space allotted for plants. They are also used for clearing backyards and empty lots populated by weeds to make room for planting new vegetation.
Types Of Herbicides
Kinds of Herbicides include the following:
Selective herbicides
Selective herbicides manipulate the growth of broadleaf weeds in backyards.
They are formulated to kill target weeds when correctly applied.
Nonselective herbicides
Nonselective herbicides are formulated to terminate all plant life they come in contact with.
They manipulate the growth of free-growing weeds separate from plants.
Pre-emergent herbicides
Pre-emergent herbicides control weed growth by inhibiting its germinating process.
They kill young weed roots or newly-germinated weed seeds.
Post-emergent herbicides
Post-emergent herbicides control weed growth after it has completed the germinating process.
They are ideal for actively growing weeds.
They kill weeds form the tip down to the roots.
Choosing Herbicides (Buying Tips)
Use: If your garden is infested with weeds, choose a selective herbicide that kills only the weeds and not your plants. Get a nonselective herbicide for controlling highway, railroad, and power line vegetation.
