Sandburs (Cenchrus species) are notorious for their sharp, painful seed heads and are a common problem in lawns, gardens, and other outdoor spaces. These weeds thrive in warm climates and can be very persistent, making them difficult to control. Fortunately, there are several herbicides available that can help effectively manage sandbur populations and restore the health of your lawn.

In this article, we will explore the best herbicides for controlling sandburs and provide a buyer’s guide to help you choose the right one for your lawn care needs. Whether you’re dealing with a mild infestation or a more severe sandbur problem, these herbicides can help you get the job done.

Best Herbicides for Sandburs

1. Roundup (Glyphosate)

Roundup (Glyphosate) is a non-selective herbicide known for its effectiveness in controlling a wide variety of weeds, including sandburs. It works by inhibiting the plant’s ability to produce proteins essential for growth, causing the plant to die.

Roundup is ideal for areas where you want to eliminate all weeds, including sandburs. However, be careful when applying it, as it will also harm surrounding plants. Spot treatment is recommended for targeted control.

2. SedgeHammer Herbicide

SedgeHammer is a selective herbicide that targets sedge and grassy weeds, making it highly effective against sandburs. It contains halosulfuron-methyl, which inhibits the plant’s ability to produce chlorophyll, leading to its death.

This product is ideal for lawns, as it won’t harm most grass species while targeting sandburs and other grassy weeds. Apply it when the sandburs are actively growing for the best results.

3. Preen Weed Preventer

Preen Weed Preventer is a pre-emergent herbicide designed to stop the germination of weed seeds, including sandburs. It’s effective when applied early in the growing season before the sandbur seeds have a chance to sprout.

Using Preen will prevent the weeds from germinating, but it will not affect existing weeds. It is a great option for preventing new infestations, especially in areas where sandburs are common.

4. Ferti-Lome Weed-Out

Ferti-Lome Weed-Out is a post-emergent herbicide that is effective against sandburs and many other broadleaf weeds. It works by killing the weeds once they have emerged, but it won’t harm most types of grass.

Ferti-Lome Weed-Out is a great choice for lawns that already have sandbur infestations. It provides visible results within a few days of application, helping to restore the beauty of your lawn.

5. Hi-Yield Weed and Grass Stopper

Hi-Yield Weed and Grass Stopper is a pre-emergent herbicide that is excellent for preventing sandbur and other grassy weeds from germinating. It’s effective when applied before the weed seeds begin to sprout in the spring.

This product is a great option if you are looking to prevent sandbur growth in future seasons, but it will not affect established weeds.

6. Image Herbicide

Image Herbicide is a selective herbicide that targets broadleaf weeds and grassy weeds like sandburs. It works by blocking enzymes that are necessary for the plant’s growth.

It is effective when used on lawns, and it won’t harm most grasses. Apply it during the growing season for best results against sandburs and other weeds.

7. Ortho Weed B Gon

Ortho Weed B Gon is a selective post-emergent herbicide that is effective at killing sandburs without harming most types of grass. It works by targeting broadleaf weeds while leaving the surrounding turfgrass unharmed.

Ortho Weed B Gon is a reliable option for lawn care and can be applied when sandburs are actively growing for the best results.

8. Southern Ag Atrazine Stump and Vine Killer

Southern Ag Atrazine Stump and Vine Killer is a selective herbicide that works well for controlling sandburs and other broadleaf weeds. It’s particularly effective in areas with established sandbur infestations.

This product is suitable for larger areas with persistent weeds. Be sure to follow application instructions to prevent damage to other plants.

Buyer’s Guide: Choosing the Best Herbicide for Sandburs

When selecting a herbicide for sandburs, consider the following factors:

1. Type of Herbicide

Pre-emergent herbicides like Preen Weed Preventer and Hi-Yield Weed and Grass Stopper are best for preventing sandbur seeds from germinating. Post-emergent herbicides, like Roundup and SedgeHammer, are effective once the sandburs have already emerged.

2. Selectivity

If you want to target sandburs without damaging your lawn, select a selective herbicide like SedgeHammer or Ortho Weed B Gon. These herbicides are designed to kill only the target weeds while leaving most grasses unharmed.

3. Effectiveness

Look for herbicides that are specifically labeled for controlling sandburs. Some herbicides work better on young, actively growing weeds, while others may be effective on established plants.

4. Safety

For pet owners or families with small children, consider using a more natural, non-toxic herbicide like Natria Lawn Weed Control. Always read labels to ensure safety and follow the application guidelines carefully.

5. Cost

When choosing a herbicide, consider the size of the area you need to treat and the price of the product. Larger areas may require more product, so calculate the cost-effectiveness of the herbicide before purchase.
