“Will Crossbow kill grass?” is the question most homeowners ask before purchasing this weedkiller.
While the concern is perfectly understandable, this brush killer can have an unfortunate reputation for killing every plant in its path.
In this article, we’ll explore the Crossbow herbicide and what it truly affects.

Will Crossbow Weedkiller Kill Your Grass?
This is because the Crossbow weed killer has been formulated to target broadleaf weeds. Broadleaf weeds are characterized by the presence of stems. Since turf grass is basically made up of blades, they will remain unaffected when sprayed with Crossbow.
This weedkiller is often used by homeowners to clear their areas of brambling plants, trailing ivies, and tough brushes. Since these types of plants are aggressive growers and invasive species, applying a brush killer is often the go-to practice. There are plenty of brush killer products to choose from on the market.
– Crossbow and Grass Varietiesg
Given that Crossbow is a brush killer, it tends to harm non-grassy plants only. Grasses like Pampas, Bermuda, Johnson, and Fescue will typically remain unaffected by this weedkiller, especially when well-established. However, it is possible to “kill” pampas grass by following our pampas removal guide.
However, St. Augustine can become susceptible to damage when applied with the Crossbow herbicide. Another grass variety to be careful about when spraying this specialty herbicide is Zoysia grass.
Generally, established Zoysia grass during its peak growing season can tolerate the Crossbow weed killer. However, it can become prone to damage or death when you apply Crossbow during or immediately after its dormant period.
– Crossbow and Other Plants
It should be noted that while applying the Crossbow weedkiller on broadleaf weeds, you should avoid spraying on windy days or near cultivated plants. Small droplets or particles may travel through the wind and land on your plants, which could damage or even kill them.
However, there are some grasses that homeowners may consider weeds. Grasses like crabgrass, foxtail, poa annua, and nutsedge will not be affected by this specialty herbicide. You will need to find other weed killers if you are planning to use the Crossbow weed killer to get rid of these grasses.
– How Long Crossbow Stays in Grassy Soil
This weedkiller will stay in grassy soil for around three weeks after application. If you are planning to cultivate plants or grass in the cleared area, it’s best to wait for a few weeks. Once sprayed, the affected plants can take anywhere from 7 to 14 days to die. During this time, it’s advisable to keep the sprayed area free from new plantings.
While grasses aren’t affected by this brush killer, it can affect the growth of grass seedlings. By waiting a few weeks to place it in your grass turf, you save more time, money, and grass seedlings.
– Using it Safely
While it’s important to read the instructions completely, the length and terminology can be confusing for some. Below is a shortened guide to using Crossbow effectively and safely:
- Wear personal protective equipment (PPE) such as gloves, face masks, goggles, and full-body suits.
- Mix the product according to the rates and volumes listed.
- Apply the herbicide at temperatures from 55 to 85 degrees Fahrenheit.
- Make sure that there is little to no wind during application in order to prevent overspray.
- Allow the herbicide to dry off for at least 6 hours, and then wait another 6 hours before allowing humans and pets to come into contact with the treated areas.
Given that Crossbow becomes waterproof 6 hours after application, ensure that you spray it on a windless, rainless day. Otherwise, you might just be wasting your Crossbow supply.
Crossbow herbicide is generally safe for use around pets, children, and livestock as long as it is applied as directed based on the instructions on the label. It is recommended to always wear PPE properly when mixing and applying this weedkiller.
Once you have applied the Crossbow weed killer, do not enter or stay in the treated areas for at least 12 hours. This will lessen the risks of any allergic reactions or contaminations.
What Are the Active Ingredients Found in Crossbow?
The active ingredients found in Crossbow are 2,4-dichlorophenoxyacetic acid (2,4-D) and Triclopyr. These components make the Crossbow herbicide so special. Both ingredients focus on and kill vines, woody plants, shrubs, and even trees without harming any of your precious grass.
2,4-D is an effective herbicide that is widely used in agriculture and lawn care to control weeds. It works by hindering the growth of certain plants by disrupting their hormonal balance.
This chemical ingredient is typically applied to the foliage of the target plants, and it is absorbed through the leaves and transported throughout the plant. It is effective at controlling a wide variety of annual and perennial broadleaf weeds, but it does not typically have any effect on grasses.
On the other hand, Triclopyr is an herbicide that is used to control weeds and woody plants. It belongs to the pyridine group of herbicides and is effective at controlling a wide variety of annual, biennial, and perennial broadleaf weeds.
The chemical works by inhibiting the synthesis of certain enzymes that are essential for plant growth and development. It is typically applied to the foliage of the target plants for weed control, and it is absorbed through the leaves and transported throughout the plant.
It can also be applied to the bark of woody plants to control them, and it is effective at controlling many species of trees and shrubs. Similar to 2,4-D, Triclopyr does not have adverse effects on grass.
1. Can You Use Crossbow Herbicide Mixed With Diesel for Grass?
Yes, you can use Crossbow herbicide mixed with diesel for grass to control stump regrowth and prevent susceptible woody growths. Mix four gallons of Crossbow in diesel oil, kerosene, No. 1 fuel oil, or No. 2 fuel oil to make 100 gallons worth of spray mixture.
The Crossbow herbicide 2.5 gallon should be adjusted accordingly to your preferred amount of mixture. By doing so, you will have a safer mixture to apply to unwanted plants in your garden. When applying this mixture, be more cautious than usual because diesel is extremely flammable.
Getting rid of unwanted plants is a tiresome chore at times. When weeds pop out without reason, the first thing that comes to mind is making sure they die off, so here’s what we need to know about using Crossbow as an effective herbicide:
- Crossbow will not kill grass. Most grasses will remain unharmed and undamaged by this powerful but selective herbicide.
- Crossbow has two ingredients that actively target non-grassy plants through their foliage and bark.
- Always use PPE to prepare, mix, and apply strong chemicals, such as Crossbow, in order to prevent accidents and injuries.
- Strong spray mixtures of Crossbow kill broadleaf weeds, such as bramble brushes, crawling ivy plants, and even trees.
- This herbicide can be safe for humans and pets to be around after application as long as it is undisturbed for at least 12 hours.
Using Crossbow is definitely safer than other herbicides, especially now that you know its effects on grass and non-grassy plants. Use what you’ve learned in this article, and tell us about your successful Crossbow weed-eliminating experience!
