What is Pre-Emergent Herbicide?
Pre-emergent herbicide is a popular way to prevent weeds from your lawn. It creates a powerful barrier on the top layer of the ground so that weeds have no chance to grow.
It might contain one or more of the following active ingredients:
- Prodiamine blocks the root from developing by stopping cell division. It’s suitable for crops such as soybeans and ornamentals.
- Dithiopyr is a mitotic inhibitor of normal cell division. Therefore, it ceases weed root extensions in lawns, vines, and ornamentals.
- Isoxaben is perfect in suppressing the growth of a wide range of weeds and has a long-lasting effect.
- Trifluralin kills weed seeds and; therefore, it controls annual grasses and broadleaf weeds.

How To Choose The Best Pre-Emergent Herbicides
Some of these factors below are essential when choosing pre-emergent herbicide products. Let’s look at them one by one!
First, you need to think carefully about how wide the treatment area you want to apply a pre-emergent herbicide. Once you estimate the coverage ground, you will know how much pre-emergent herbicide you need to order.
It would be better if you don’t over-buy and have to keep it in stock. Usually, each application can last at least three months to a year, so you occasionally reapply 2 or 3 times in a row. Otherwise, you have to preserve it well for later use.
You should follow the instruction on the product label to achieve the optimal result and ensure the expected quantity and quality.
Liquid and Granular Form
There are two available forms of pre-emergent herbicide. They are liquid and granules.
Granular products are simpler to use and often comes with more affordable price. They might include some measurement scoops to help you with your application.
If you prefer a more precise distribution, you might opt for the liquid form, which is one of the advantages of granular ones. Not to mention, they can offer you excellent coverage.
For this type of pre-emergent herbicide, you will need the right sprayer applicator to use.
Targeted Grass Weeds and Broadleaf Weeds
Each product can control and suppress a list of grass weeds and broadleaf weeds. You can refer to these targeted weeds by reading the label which is included in the package before buying.
It’s essential that you can choose the product which truly serves your purposes.
