Purslane (Portulaca oleracea) is a hardy, fast-growing weed that can quickly take over garden beds and lawns. Known for its succulent, fleshy leaves and ability to spread rapidly, purslane can be difficult to control without the right herbicide.

The key to effectively managing purslane is selecting an herbicide that targets this specific weed while minimizing damage to other plants in the area.

In this guide, we’ll explore some of the best herbicides for controlling purslane and keeping your garden or lawn healthy. Whether you’re dealing with a small patch or a large infestation, the following herbicides can help you regain control.

10 Best Herbicides for Purslane

1. Roundup (Glyphosate)

Roundup is a well-known herbicide that uses glyphosate as its active ingredient to kill a broad spectrum of weeds, including purslane. It works by targeting the plant’s ability to synthesize amino acids, leading to its eventual death.

Roundup is effective when applied directly to the leaves and stems of the weed. However, it is non-selective, so take care to avoid contact with desirable plants. Use a shield or sponge to target only the purslane.

2. Preen (Trifluralin)

Preen is a pre-emergent herbicide that prevents weed seeds from germinating. It is ideal for controlling purslane when applied before the seeds sprout in your garden or lawn.

By creating a barrier in the soil, Preen can prevent purslane seeds from taking root, thus stopping the weed before it even has a chance to grow. It is safe to use around many desirable plants, making it a great option for long-term weed control.

3. Ortho GroundClear (Pelargonic Acid)

Ortho GroundClear is a non-selective herbicide that works quickly to kill weeds like purslane by disrupting the plant’s cell structure. It is a great choice for fast-acting weed control.

Since it is non-selective, you must take care when using it to avoid damaging surrounding plants. Apply GroundClear directly to the purslane leaves and stems to effectively kill the weed.

4. Tenacity (Mesotrione)

Tenacity is a selective herbicide that targets both grassy and broadleaf weeds, including purslane. It works by inhibiting chlorophyll production in the weed, causing it to die.

Tenacity is effective when applied to young, actively growing purslane. Since it is selective, it is safe to use around most desirable plants when applied as directed.

5. Vantage (Quizalofop-P-Ethyl)

Vantage is a selective herbicide designed to target grassy weeds, but it can also work on purslane if applied at the right time. It interferes with the weed’s ability to produce amino acids, leading to its death.

Vantage is particularly useful for controlling grass-like weeds that compete with other plants in the garden, including purslane.

6. Spectracide Weed Stop (2,4-D, Dicamba, Mecoprop-P)

Spectracide Weed Stop contains a combination of active ingredients that work to control a broad spectrum of weeds, including purslane. It is effective for both post-emergent and pre-emergent weed control.

Use Spectracide when purslane is actively growing for the best results. Be cautious when applying around sensitive plants, as it may harm them.

7. Glyphosate (Generic)

Glyphosate is the active ingredient in many herbicides and works as a non-selective herbicide to kill a wide range of weeds, including purslane. It is effective when applied directly to the foliage of the weed.

Since it is non-selective, take care not to apply it near desirable plants. Use a targeted application method, such as a sponge or shield, to minimize drift.

8. Pramitol (Prometon)

Pramitol is a post-emergent herbicide that provides long-lasting control of broadleaf and grassy weeds, including purslane. It is effective for eliminating existing weeds in larger areas.

Apply Pramitol when purslane is actively growing. It is a non-selective herbicide, so make sure to protect surrounding plants.

9. Southern Ag (Triclopyr)

Southern Ag is a selective herbicide that targets broadleaf and woody plants, making it effective for managing purslane in certain environments. It works by inhibiting the growth and development of the weed.

Use Southern Ag carefully to avoid harming surrounding desirable plants, and apply it directly to the weed for the best results.

10. Natural Armor (Citrus Oil)

Natural Armor is a natural herbicide made from citrus oils. It works by breaking down the cell structure of weeds like purslane, leading to their quick death.

Natural Armor is non-toxic and safe for use around pets and children, making it a great organic option for weed control. It is ideal for those looking for a more environmentally friendly herbicide option.

Buyer’s Guide: Choosing the Best Herbicide for Purslane

When selecting an herbicide for purslane, consider the following factors:

1. Selectivity

Choose a herbicide that targets purslane specifically, without harming other plants in your garden. Products like Vantage are selective and can be used without damaging surrounding plants.

2. Application Method

Consider how the herbicide is applied. Non-selective herbicides like Roundup require more care during application to avoid harming desirable plants, while pre-emergent herbicides like Preen prevent weed growth before they even sprout.

3. Environmental Impact

If you are looking for an eco-friendly option, choose herbicides made from natural ingredients, such as Natural Armor, which use citrus oils to kill weeds without harming the environment.

4. Effectiveness

Different herbicides work at different rates. Some are faster-acting, while others offer long-term control. Consider your immediate needs and the type of control you want.

5. Cost

Herbicide prices vary widely. Consider your budget and look for a product that balances effectiveness with cost.

Conclusion

Successfully controlling purslane requires the right herbicide and application method. The products listed above are effective at targeting this persistent weed, ensuring your garden remains healthy.

By selecting a herbicide suited to your needs and following application guidelines, you can enjoy a weed-free garden without damaging surrounding plants.
