Herbicides are Weedkillers
Herbicides, are commonly known as weedkillers, are pesticides used to kill unwanted plants Selective herbicides kill specific targets while leaving the desired crop relatively unharmed. Some of these act by interfering with the growth of the weed and are often synthetic “imitations” of plant hormones.
Herbicides used kill all plant material with which they come into contact. Some plants produce natural herbicides, such as the genus Juglans (walnuts), or the tree of heaven.
Herbicides are widely used in gardening, agriculture and in landscape turf management.
Post-emergence herbicides act on visible and mature weeds rather than on seeds, This is the main reason that the post-emergence herbicides are most widely used across the world.
Some Post-emergence herbicides are systemic and the chemicals must be absorbed through the weed’s leaves, stems or roots. This process kills the plant by interfering with its metabolism (eg glyphosate or glufosinate).
Contact herbicides are less effective since they kill only the plant parts on which they are sprayed.
Majority of the herbicides available these days are synthetic in nature. These herbicides are manufactured compounds that do not normally occur in nature.
Natural herbicides are products whose active ingredients originate in a plant or mineral.
One of the cheapest and most effective herbicide and which is generally easily available in the garden stores is a105 solution of vinegar.
If you are going to purchase herbicides it is important to ensure that whatever proprietary product you decide to buy, first read the label to make sure how it works, on what kinds of weeds, and what active substance it contains.
