Post-Emergent Herbicides for Killing Weeds – Usage Tips

Post-Emergent Weed Killing Herbicides: Common Weeds appearing in the garden are an unpleasant sight for any modern-day gardener. This is especially true if you have been working hard over many months to grow a beautiful garden or lawn. If plucking the vexing plants for hours on end isn’t your thing, then you can consider using a post-emergence herbicide to combat these pesky weeds.

In this article, we will explain post-emergent herbicides, and how they might help you keep your garden beds looking their best?

What are Post-Emergent Weed Killing Herbicides?

Weeds are killed by post-emergents after they have sprouted their nasty little heads. The “post” component of this herbicide relates to the fact that it is intended to be used on weeds that are already present in your garden. Pre-emergent herbicides are used before weeds appear.

Proper usage of post-emergence weed killers can reduce existing weeds and help prevent new ones from growing. There are several varieties of post-emergent chemical weed killers, so read the product description carefully and select the weeds you need to manage.

Post-emergent weed killers may target the leaves or spread systemically to the plant’s roots. They are available in spray-on or granular forms. They are most effective in weed-infested regions, but you must exercise caution when spraying to avoid spray spread or interaction with non-target plants.

Carefully examine the herbicide product labels for post-emergent details such as the types of weeds the product is effective against, the manner of application, and whether the chemicals are appropriate to use on grass turfs or other places where non-target plant exposure is unavoidable.

Types of Post-Emergent Weed Killers

Post-Emergence chemical formulas can be broadly classified into two types based on their method of application.

  1. Systemic herbicides are particularly effective against perennial weeds since these are absorbed directly by the plant and then spread throughout it for maximal lethal impact.
  2. Contact herbicides, which are used on annuals as well as smaller weeds, destroy the exposed portion of the plant. This may appear insignificant, but for the large variety of weeds, the death of the leaf foliage is sufficient to kill the entire plant.

Post-Emergent herbicides can also be broadly categorized as selective or non-selective broad-based weed killers depending on their target weeds.

How to Use a Post Emergent Herbicide in your Garden?

For the best effects, post-emergent weed killers must be activated and applied under carefully regulated settings. Once you’ve determined what your weed demands are and which formula to employ, you must consider the pace of application, residual action, as well as the prevention of contamination or leaching in specific soils.

  1. Apply on a dry day where the product will be able to dry for a minimum of 30 minutes to 8 hours.
  2. Temperatures ought to be between 55 to 80 degrees Fahrenheit for optimal results (12-26 C.).
  3. After the drying time, the herbicide must be watered in.
  4. Avoid spraying them on a windy day.
  5. Follow the measures recommended by the manufacturer to prevent skin contact and lung inhalation.
