What Types of Weed Killers are There?

Before you settle on the herbicide you want, ask yourself if your goal is to eliminate the weed problem or prevent it. The answer to this will allow you to choose the best weed killer spray that will work wonders for you.

Here are the two types of weed killers.

1. Post-Emergent Weed Killers

This type of weed killer is popular when it comes to weed control.

Once you spray this type of best weed killer on the weeds, it penetrates the weed's system up to the roots and kills the plant.

Unfortunately, most of these post-emergent weed killers are non-selective. This means that if you use them on your lawn, they will most likely harm the weeds and grasses.

Pre-emergent herbicides stop the growth of new root cells in the weeds while they are still babies. Many weed killers that fall under this type can eliminate various types of weeds on your lawn, including crabgrass.

The advantage of these weed killers is that they don't mess up the other plants in your garden or lawn. The reason is that these other plants already have developed roots. Another point to note is that these weed killers need water to activate them.
