Queen Anne’s lace (Daucus carota) is a common biennial weed found in lawns, gardens, and along roadsides. Its fern-like leaves and delicate white flowers may seem charming, but it can quickly become invasive. If you are struggling to control Queen Anne’s lace, there are several effective herbicides available to manage and eliminate it.

This guide covers some of the best herbicides to control Queen Anne’s lace, offering both selective and non-selective options for different lawn and garden needs.

Best Herbicides for Queen Anne’s Lace

1. Roundup (Glyphosate)

Roundup is a non-selective herbicide that targets all plants it comes in contact with, including Queen Anne’s lace. It is a powerful option for eliminating this invasive weed, especially in areas where you don’t mind killing surrounding vegetation.

Roundup works by inhibiting the plant’s ability to produce essential proteins, leading to its death. However, care must be taken when applying it to avoid damage to desirable plants nearby.

2. Crossbow (Triclopyr + Fluroxypyr)

Crossbow is a selective herbicide designed for woody plants and tough weeds like Queen Anne’s lace. It is a systemic herbicide, meaning it is absorbed by the plant and travels through the vascular system to kill it from the roots up.

Crossbow is effective in eliminating Queen Anne’s lace in both turf and garden settings. It’s especially useful for larger infestations where mechanical removal is not feasible.

3. 2,4-D

2,4-D is a selective herbicide widely used for controlling broadleaf weeds, including Queen Anne’s lace. It works by disrupting the plant’s cell growth and can be applied in various lawn care scenarios.

2,4-D is effective when applied in the growing season, targeting Queen Anne’s lace without harming most grasses. It’s an affordable and efficient option for broadleaf weed control.

4. Tordon (Picloram)

Tordon is a systemic herbicide that is highly effective against deep-rooted perennial weeds like Queen Anne’s lace. It is especially useful for controlling stubborn, established weeds in turf and non-crop areas.

Tordon works by being absorbed into the plant’s roots and disrupting its ability to grow. It is highly effective, but should only be used in non-crop areas as it can be toxic to surrounding vegetation.

5. Weed-B-Gon (2,4-D, Mecoprop-P, Dicamba)

Weed-B-Gon is a selective herbicide that targets broadleaf weeds such as Queen Anne’s lace without harming grasses. It combines several active ingredients, including 2,4-D, to kill weeds by disrupting their growth processes.

It’s effective for smaller patches of Queen Anne’s lace and can be safely used in lawns. However, avoid applying it during the hot summer months to minimize the risk of damage to your lawn.

6. Finale (Glufosinate)

Finale is a non-selective herbicide that works by inhibiting the plant’s production of essential amino acids, leading to rapid death. It is effective against Queen Anne’s lace and other weeds.

Finale is ideal for smaller, contained applications. It’s a good option for spot treatment, but it will also kill any other plants it contacts, so use with care.

7. Chateau (Flumioxazin)

Chateau is a pre-emergent herbicide that prevents Queen Anne’s lace and other weeds from germinating. It is highly effective when applied before the seeds of Queen Anne’s lace sprout in early spring.

Chateau is particularly useful for preventing future infestations, providing long-lasting protection from weeds. It is also safe for use in many ornamental beds and turf areas.

Buyer’s Guide: Choosing the Best Herbicide for Queen Anne’s Lace

When selecting a herbicide for Queen Anne’s lace control, consider the following factors:

1. Pre-emergent vs. Post-emergent

Pre-emergent herbicides like Chateau work before the weed germinates, while post-emergent herbicides like Roundup or 2,4-D are used to kill actively growing plants.

2. Selectivity

If you want to preserve your grass or desirable plants, consider a selective herbicide like 2,4-D, which won’t harm most turfgrass. Non-selective options like Roundup are effective but will kill all plants it contacts.

3. Timing

Pre-emergent herbicides should be applied in early spring, while post-emergent herbicides are most effective when Queen Anne’s lace is actively growing.

4. Application Method

Some herbicides require spot treatment, while others are suitable for broadcast application across large areas. Choose the method that best suits your needs.

5. Environmental Impact

Be mindful of the herbicide’s environmental impact. Some chemicals, like Tordon, are more harmful to the surrounding ecosystem, while others, like Chateau, are safer for use around ornamental plants.

Best Herbicide for Queen Anne’s Lace FAQs

• What is the best time to apply herbicide for Queen Anne’s lace? Pre-emergent herbicides should be applied in early spring before the weed germinates, while post-emergent herbicides should be used during active growth.
• Can I use these herbicides on my lawn? Many of these herbicides are safe for lawns, but always check the label for compatibility with your grass type.
• Are there organic options for controlling Queen Anne’s lace? Yes, options like vinegar-based herbicides can be effective for spot treatment, but they may be less reliable than chemical herbicides.
• How long does it take for herbicides to kill Queen Anne’s lace? Post-emergent herbicides usually take 7-14 days to show results, while pre-emergent herbicides will prevent germination over the course of several weeks.
• How can I prevent Queen Anne’s lace from returning? Regular maintenance, including mowing and applying pre-emergent herbicides, can help prevent future infestations.
• Can I use Roundup on my garden? Roundup is non-selective and should only be used carefully in areas where you don’t mind killing other plants.
• What is the most effective herbicide for large Queen Anne’s lace infestations? Crossbow and Tordon are highly effective for large, established infestations.

Conclusion

Controlling Queen Anne’s lace requires careful planning and the right herbicide. Whether you’re using a pre-emergent to prevent new seeds from sprouting or a post-emergent to eliminate an existing infestation, choosing the best herbicide for the job is key to achieving a weed-free landscape. By considering factors such as the type of herbicide, timing, and selectivity, you can effectively manage Queen Anne’s lace and protect your turf and garden.
