What Is Post-Emergent Weed Application?
A nice, well-manicured lawn or garden can be a centerpiece for any home during the spring and summer months. Unfortunately, weeds can taint lawns and gardens to the point they become eyesores.
Fortunately, post-emergent weed applications can be of assistance in helping a gardener and/or homeowner win the battle against pesky weeds. What Is the Definition of Post-Emergent?
When describing weed killers, post-emergent references the herbicide's ability to eliminate weeds after they have already formed and are visible on lawns or inside gardens. These
chemicals differ from pre-emergent weed eradicating applications, which are employed to kill weeds before they grow. Post-emergent preparations not only eradicate existing weeds, but may be of use in preventing future weed growth. How Do Post-Emergent Weed Killers Work?
These herbicides eliminate weeds in one of two ways. Some possess the ability to attack the
offending weed directly, while others morph into a particular plant's root and attack it from the ground up.
What Are the Different Types Of Post-Emergent Weed Killers? These substances are broken down into two major categories: o Systemic Herbicides o Contact Herbicides
Systemic herbicides penetrate a weed and eradicate it by destroying it in its entirety. Contact Herbicides are often potent enough to kill a weed on contact.
Post-emergent weed applications may also be labeled as selective and non-selective:
Selective herbicides are typically used to eliminate specific weeds collecting on smaller, grassy areas. Non-selective weed preparations are often successful in eradicating most weeds and employed in larger areas, such as fields.
Types of Weeds Post-Emergent Weed Applications Eliminate
Post-emergent chemical preparations are effective in killing perennial weeds, including
Quackgrass, Bindweed, Nutsedge and Thistle. They will also kill annual, leaf-shaped plants
which do not have the appearance of grass and weeds like Crabgrass, which does resemble grass.
