The Best Crabgrass Killer: What and How to Choose?

There are few considerations to take heed of when choosing the best crabgrass killer. And as the market is flushed with a variety of alternatives now, it’s a must that you’re acquainted with these factors first.

For you to get the best out of your purchase relative to its features and your budget, ensure that you list the following on your checklist:

#1 Pre- and post-emergent herbicides

Gardener spraying herbicide

Herbicides are by far the most effective treatment when aggressive weeds, such as crabgrass, take control, of your hard. And as crabgrass killers are almost made of herbicides, ensure that crucial ingredients or components are present in them.

The first one that should be included is the pre- and post-emergent herbicides.Pre-emergent herbicides will act as a blocker of grass enzymes right when the seeds are germinating. As such, the growth of the grass or weed is stopped effectively.

This type of herbicide is best suggested to be applied only in summer or when temperatures are usually high. On the other hand, post-emergent herbicides are utilized right when the weed’s growth is done or when it’s already spread in the garden.

This type of herbicide is highly recommended when application of the pre-emergent herbicide seems to have not completely eradicated all weeds in the problematic area. Also, this herbicide has a longer, eliminating effect than the former one.

#2 Contact and systemic herbicide

All types of weeds are bound to make contact with each other. This can be stunted through contact herbicides in which it’s tasked to breaking down the process of photosynthesis along with chlorophyll. Consequently, this starves the targeted plants which should die down eventually.

When contact herbicides are applied to weeds, they also cause abnormal growth and disproportioned distribution of nutrients right in its system. This in itself causes strangulation in plants which should hasten the process of weed elimination.

The next type that is present in crabgrass killers is systemic herbicides. The method it employs takes more time than contact herbicides. Despite this, it should also leave a lasting effect on the treated plants.

#3 Selective and non-selective herbicides

As the term itself implies, selective herbicides are specific to their functions. Meanwhile, this type of herbicide is widely chosen when you’re just looking to get rid of grass around a plant or a flower. If you want an all-killing solution, non-selective herbicides are the way to go.

It should annihilate almost all types of species in the plant kingdom. But as it is effective as an herbicide, its known drawback evidently is also where it’s good at – killing plants. As it goes, choose this alternative only when you’re planning to begin doing your garden right from scratch.
