The Syngenta turf grass herbicide is the ultimate option for your house. Diluted formula is used for the perfect results. In fact you only need to add 1 part of tenacity grass killer in about a gallon of water. Of course, I recommend you make it stronger if you think the ratio is not working for you.

What are Crabgrasses?

The crabgrass weeds from my garden

Talking about crabgrasses, these would be one of the irritating grasses that you would excitedly get rid out of your lawn. It has long leaves (finger-like) that have dark green color. It annoyingly grows in bunches and makes sure that its roots are buried deep within the soil that’s why it takes time and effort for you to pull this type of grass.

Crabgrasses are the type of annual plants that could flourish for some months.

When to Apply Crabgrass Preventer?

Applying crabgrass killer is just so simple. Here are some notes when applying herbicide.

  1. Whatever type of crabgrass killer you have, you’ll always notice the application instructions on its label. Take time to read and follow it strictly.
  2. When you saw weeds growing in your garden, immediately apply the best crabgrass killer you’ve chosen.
  3. Also, take note that you need to apply herbicide when the temperature is eighty-five degrees. One of the best seasons to apply herbicide is during the fall season.

What Factors to Consider?

1. Coverage

The first and foremost thing that I find is important is the coverage of the formula. You need to see how efficient it is. Keep in mind this does not mean that a big bottle will cover more area. The coverage depends on the strength and the formula of the solution. Some chemicals need dilution and some need high concentration spraying.

2. After affects

Another very important factor that there is to look about is the after affects. Getting a crabgrass killer that in turn will kill everything in your garden in not the good way to go. In fact there are some that strengthen your plants further. Make sure that you know that your killer is not affecting the vegetation.

3. Environment/Area

Crabgrass killers are especially for different weathers. Different environments have different types of weeds and crabgrass they need treatment accordingly.

Additionally, some solutions are too strong for crabgrass. Make sure that you get something that is especially for this and the area you are living in. 

4. Convenience

One of the most important things is convenience. There are many different killers out there that need extra ingredients. Some are ready to use by just adding water. It is more suitable to opt for the complete package to avoid any ruckus.

While we are on the matter, you need to make sure that your solution is easily diluted in water. Some solutions do not dilute easily. Make sure you check the concentration and see if it dilutes in water.

5. Cold vs. warm Temperature

In comparison to warm to coldThe temperature determines both the weed species that will be targeted and the degree of success that the weed killer will have. Herbicides are most effective against weeds that are actively growing at the time of application. When the soil temperature reaches approximately 55 degrees Fahrenheit in the spring, the seeds of crabgrass begin to germinate. The crabgrass plant matures and produces more seed during the summer months, but as fall and winter arrive, the plant passes away.

If you live in an area with a chilly climate, it's possible that a single application of pre-emergent in the spring will be enough to get rid of crabgrass. Crabgrass can be efficiently controlled in a region that has a warm environment by applying pre-emergent several times over the course of the growing season, if necessary, in conjunction with spot treatments with post-emergent herbicide.

6. Comparing Organic and Inorganic

Are weed killers made from organic ingredients? Yes! The organic weed killers are derived from corn gluten, a byproduct of cornstarch production. If you use it to control crabgrass, the gluten will prevent the seeds from developing, and as a result, the lawn will be free of the weed over time. The nitrogen component in some of these weed killers aids in the maintenance of lush, healthy grass.

Inorganic weed killers are sometimes called herbicides. They are made of chemicals and can be very specific about which weeds they kill. They can even be systemic, which means that the chemical will kill the plant all the way down to the root because it has gone through the whole plant. Before you use a product, make sure to check the label to make sure that any chemicals in it won't hurt children or pets.

7. Liquid vs. Granular

You have the option of purchasing either a granular or liquid form of the product that you want to buy. The application of the liquid product is accomplished through the utilization of a sprayer of some kind, specifically a tank sprayer. You can use the tank sprayer to target specific weeds you notice growing in your lawn and spray them with the appropriate herbicide. The garden sprayer is a device that is attached to your garden hose and ensures that the correct proportions of water and weed killer are mixed together. Applying the liquid product in this manner is a quick and uncomplicated process.

Granular products are applied to the grass using a hand spreader or a wheeled spreader, respectively. A bowl or tank is contained within a wheeled spreader, and the opening of the spreader can be adjusted to the appropriate level. When you move the spreader across the lawn, the product is dispensed onto the grass and distributed evenly across the surface of the lawn. Many of the granular treatments also contain fertilizer, which helps your grass become greener, thicker, and/or stronger at its roots.

8. Price

How much money should you be prepared to pay for a crabgrass killer? The cost of crabgrass suppressants varies depending on whether they are pre-emergent or post-emergent varieties. To cover a 5,000-square-foot area with post-emergent killers, it normally costs between $5 and $15. Typically, pre-emergent killers cover that area for $15–$20 per application, according to our research.

Crabgrass killer - Affecting Health?

One of the most basic things in the world is that crabgrass killers are harmful to the human and animal health.

Inhaling them accidentally causes people to die as well. While human beings can take care of themselves, animals are hurt the most.

This is probably one reason that in certain parts of France, Crabgrass killers are banned. We don’t know when they will lift the ban or what their conditions are, but France realizes that these things might not be suitable to the ecosystem. However, the real controversy is that farmers and locals are still using it despite the ban.

What’s the best way to use crabgrass killer?

A few tricks to keep in mind when you use crabgrass killer are the following;

  • Make sure that you have the system charted out. Timing is the key. Weather patterns and seasons are also a crucial watch.
  • Use the ground temperature to work your way with the crabgrass killer. The soil temperature is difficult to measure.
  • If your lawn is newly needed, make sure to wait for three mows of lawn before you start with crabgrass killers.
  • Make sure that you apply the killer evenly. Missing a spot means that all your efforts will go down the drain.

The Systemic and Contact Herbicide

The systematic herbicide is a crabgrass killer that would need more time to take effect. But even though it could not affect as fast as others, surprisingly, this has a long-lasting impact on plants.

On the other hand, if you want a type of poisoning method of killing crabgrasses, you may choose the contact herbicide because it poisons the plants in your garden.

Moreover, this herbicide initiates abnormal growth-altering the plant’s system and creates proportioned nutrient-distribution. This could quickly kill those annoying crab grasses. Not a bad choice, indeed. 

Pre-Emergent vs. Post-Emergent Herbicides

Mostly, crabgrass killers are herbicides, and you could find plenty of it, with different brands and effects, in the market.

The emergent herbicides include the pre as well as post-emergent herbicides. The first one is effective in blocking a particular grass’ enzyme during its seed germination.

This is why pre-emergent herbicides block the weed or grass from multiplying or growing. It’s advisable to use when the temperature is high such as during summer.


Crabgrasses in the garden

Meanwhile, the post-emergent herbicide is being used only after the crab grasses have flourished or grown in your garden. It’s applied when there are still weeds left in your garden after you’ve used the pre-emergent herbicide.

If you want longer or efficient effect, you can use this throughout the season since it could not be that effective when dealing with established or very thick crab grasses.

Non Selective and Selective Herbicides

Are these good options? Well, if you’re a gardener that would only want to eliminate a particular type of weeds around your beloved flower, the selective herbicide would be one best crabgrass killer to have. As its name connotes, it’s excellent in eliminating a particular type of plants only.

But if you need the type of herbicide that would execute various kinds of plants, then having the non- selective herbicide will work great for you. But on some point, this could cause some risks on some useful plants in your garden.

This herbicide is an excellent option if you’re just about to start your garden. But if it’s already established, then having the selective herbicide is better.
