Crossbow vs. Roundup: Choosing the Right Herbicide for Your Needs

When it comes to tackling unwanted weeds and vegetation in your garden, two popular herbicides stand out: Crossbow and Roundup. Each of these products has its unique characteristics and applications. In this comparison guide, we’ll explore the differences between Crossbow and Roundup, helping you make an informed choice for your specific weed control needs.

Understanding the Basics

Crossbow Herbicide:

Crossbow is a selective herbicide that’s primarily designed for controlling woody plants and broadleaf weeds in non-crop areas. It’s especially effective against invasive species like poison ivy, blackberry bushes, and thistle.

Roundup Herbicide:

Roundup, on the other hand, is a non-selective herbicide that’s widely used for killing a broad spectrum of weeds, grasses, and vegetation. It contains glyphosate, a potent active ingredient that inhibits plant growth.

Key Factors to Consider

1. Selectivity:

Crossbow is selective, meaning it targets specific types of plants while leaving other vegetation unharmed. Roundup, being non-selective, kills most plants it comes into contact with. Consider your specific weed problem to determine which selectivity suits your needs.

2. Target Weeds:

Crossbow is particularly effective against woody plants and broadleaf weeds. If you have a garden with these types of invasive species, Crossbow might be the better choice. Roundup is suitable for a broader range of weeds, including grasses.

3. Mode of Action:

Crossbow contains two active ingredients, 2,4-D and triclopyr, which work together to kill targeted plants. Roundup, with glyphosate as its primary active ingredient, inhibits the production of essential proteins in plants, ultimately leading to their demise.

4. Residual Effects:

Crossbow can have residual effects in the soil, which may affect plants you want to grow later. Roundup, when used as directed, usually breaks down in the soil and does not leave long-lasting residue.

5. Application Methods:

Both Crossbow and Roundup are available in various formulations, including concentrated solutions, ready-to-use sprays, and more. Consider the application method that best suits your needs and preferences.

Making Your Decision

To choose between Crossbow and Roundup, start by identifying the specific weeds or vegetation you need to control. If you’re dealing with woody plants and broadleaf weeds in a non-crop area, Crossbow is a suitable choice. However, if you need a versatile, all-purpose herbicide for a wide range of weeds and are willing to accept non-selective effects, Roundup may be the better option.


In the Crossbow vs. Roundup battle, the winner depends on your specific weed control requirements. Crossbow excels at targeted control of woody plants and broadleaf weeds, while Roundup provides a broader spectrum of weed control but without selectivity. Carefully assess your needs and consider factors like selectivity, target weeds, mode of action, residual effects, and application methods before making your decision.

For more detailed guidance, consult with a gardening or landscaping professional to ensure you choose the herbicide that aligns with your specific needs and environmental considerations.


1. Is Crossbow safe to use around pets and wildlife?

Crossbow should be used with caution around pets and wildlife. While it is designed for targeted weed control, it’s essential to follow the manufacturer’s instructions regarding application and drying times. Keep pets and wildlife away from treated areas until the product has dried completely.

2. Can I use Roundup in my vegetable garden?

Roundup is a non-selective herbicide, which means it can kill a wide range of plants, including vegetables. It is not recommended for use in vegetable gardens or areas where you intend to grow edible crops, as it may harm desirable plants. Consider alternative weed control methods in such areas.

3. Are there any environmental concerns associated with using Roundup?

Glyphosate, the active ingredient in Roundup, has raised environmental concerns due to its potential impact on non-target plants and aquatic ecosystems. To minimize environmental effects, use Roundup sparingly and according to the label instructions. Consider alternative herbicides for sensitive environments.

4. Can I use Crossbow and Roundup together for better weed control?

While it is possible to use both herbicides, it’s essential to exercise caution. Combining herbicides can increase the risk of overapplication and potential harm to non-target plants. If you choose to use both, do so selectively and ensure compatibility with your specific weed control needs.

5. How long does it take for Crossbow and Roundup to start working on weeds?

The time it takes for Crossbow and Roundup to show visible results varies based on factors like weather conditions, weed type, and the health of the plants. Generally, you may start to see effects within a few days to a few weeks after application.

6. Can I use Crossbow and Roundup during rainy or windy conditions?

Using herbicides during rainy or windy conditions is not advisable, as it can lead to product drift and reduced effectiveness. Ideally, apply these herbicides on a calm day when there is no rain in the forecast to ensure proper coverage and reduced risk of unintended harm to nearby plants.

7. Are there any organic alternatives to Crossbow and Roundup?

Yes, there are organic and natural alternatives to synthetic herbicides like Crossbow and Roundup. These may include vinegar-based herbicides, steam weeding, manual removal, and mulching. Organic options are generally considered safer for the environment and may be suitable for use in organic gardening.

8. What safety precautions should I take when using Crossbow and Roundup?

Always read and follow the label instructions provided by the manufacturers. Wear appropriate protective clothing, including gloves, goggles, and long sleeves, when handling these herbicides. Store them in a secure location away from children and pets, and dispose of empty containers according to local regulations.

9. Can I use Crossbow and Roundup to control weeds in my lawn?

Using Crossbow and Roundup directly on your lawn is not recommended, as they can harm desirable grasses. Consider using specific lawn weed control products that target weeds while preserving your lawn grass.

10. Are there any restrictions on using Crossbow and Roundup in my area?

Local regulations may impose restrictions on the use of herbicides like Crossbow and Roundup. Check with your local agricultural extension office or environmental agency for information on any specific regulations, permits, or guidelines in your area. Always comply with local laws and regulations when using herbicides.
