Vetch is a persistent, fast-growing weed that can take over your garden, lawn, or pasture, especially in the spring and fall. Known for its ability to spread quickly, vetch can outcompete desirable plants for nutrients and space. Fortunately, with the right herbicide, you can manage vetch and stop it from becoming a nuisance in your yard or field.

In this guide, we will explore some of the best herbicides for vetch control. These products range from non-selective options to selective herbicides, offering flexibility depending on the severity of your infestation and the surrounding plants you need to protect.

Best Herbicides for Vetch

1. Roundup (Glyphosate)

Roundup (Glyphosate) is one of the most effective non-selective herbicides available for killing vetch. It works by disrupting the plant’s ability to make proteins, which leads to its death. Roundup is highly effective for controlling vetch and other weeds in non-crop areas, driveways, and lawns.

While effective, Roundup should be applied with caution, as it will kill any plant it contacts, including your desirable plants. It is most effective when applied directly to the foliage of the vetch.

2. 2,4-D (Weed-B-Gon)

2,4-D is a selective herbicide that is effective in controlling broadleaf weeds like vetch. It is ideal for use in lawns and turf areas where you want to kill vetch without harming grass. 2,4-D works by disrupting the plant’s growth hormones, leading to its eventual death.

For best results, apply it during the active growth period of vetch. While it is generally safe for lawns, care should be taken not to apply it to sensitive plants or non-target vegetation.

3. Garlon 4

Garlon 4 is a selective herbicide that is effective for controlling perennial weeds like vetch. It works by preventing the plant from taking up nutrients and water, leading to its demise. Garlon 4 is often used for managing woody plants and broadleaf weeds.

It is especially useful for large infestations in pastures, fields, and non-crop areas. When applying Garlon 4, be sure to follow the instructions carefully, as improper use may damage nearby plants.

4. Ortho WeedClear

Ortho WeedClear is a selective herbicide that works effectively on broadleaf weeds, including vetch. It kills weeds down to the root, preventing regrowth and reducing the chance of reinfestation.

This herbicide is ideal for use in lawns and garden beds where vetch has taken hold. It is safe for grass and other desirable plants when used according to the manufacturer’s instructions.

5. Crossbow

Crossbow is a non-selective herbicide that is effective in controlling vetch and other woody and broadleaf weeds. It contains two active ingredients—Triclopyr and 2,4-D—that work together to kill the weed by attacking both the roots and foliage.

Crossbow is effective for large infestations and is commonly used in pasture management, roadside maintenance, and forests. However, it can harm non-target plants, so it should be used with care.

6. PBI/Gordon SpeedZone

PBI/Gordon SpeedZone is a selective herbicide that works well in killing broadleaf weeds, including vetch, without harming most grass varieties. It is fast-acting, and you can see results within a few days of application.

SpeedZone is ideal for lawns, golf courses, and other turfgrass areas where vetch is an issue. It is safe for most grass types and provides long-lasting control when applied during the growing season.

7. Advance 50DF

Advance 50DF is a systemic herbicide that effectively controls a variety of broadleaf weeds, including vetch. It is absorbed by the plant’s leaves and translocates to the roots, killing the plant from the inside out.

Advance is suitable for large-scale applications in agricultural fields or areas with a significant weed problem. It can be harmful to other plants, so it should only be used in areas where you want to eliminate vetch.

8. PastureGard HL

PastureGard HL is a powerful herbicide that is commonly used for controlling tough perennial weeds like vetch in pastures, rangelands, and fields. It contains the active ingredient Triclopyr, which disrupts the plant’s growth processes and kills it over time.

PastureGard HL is highly effective on woody plants and broadleaf weeds but should be applied carefully around desirable plants. It’s best used in areas where vetch has established deep roots.

9. Vantage

Vantage is another Triclopyr-based herbicide designed for use on tough weeds like vetch. It is effective on both woody plants and broadleaf weeds, providing long-lasting results.

Vantage is ideal for large infestations in pastures and fields. It may take some time to see the full effects, but it will significantly reduce the presence of vetch in the treated area.

10. Fusilade II

Fusilade II is a selective herbicide that targets grasses but also works well on certain broadleaf weeds like vetch. It works by interfering with the plant’s ability to produce fatty acids, causing the plant to die.

Fusilade II is ideal for lawns and other grass areas that are plagued with vetch. It provides effective control without harming the grass, making it an excellent choice for turf management.

Buyer’s Guide: Choosing the Best Herbicide for Vetch

When selecting a herbicide to control vetch, keep in mind the following considerations:

1. Selectivity

Decide whether you need a selective herbicide that will target only vetch or a non-selective option. Selective herbicides like 2,4-D and SpeedZone are ideal for lawns, while non-selective herbicides like Roundup are best for larger areas or where surrounding plants aren’t a concern.

2. Application Method

Choose a herbicide with an application method that suits your needs. Some products require spot treatment, while others are suitable for large-scale applications. Read the product label to determine how best to apply it to ensure maximum effectiveness.

3. Speed of Action

If you need fast results, opt for a herbicide that works quickly, like SpeedZone. For long-term control, a systemic herbicide like Crossbow or Garlon 4 may be a better option.

4. Safety

Be sure to use the herbicide according to the manufacturer’s instructions, especially if you have pets or children. Some herbicides can be harmful to non-target plants, so always use caution when applying near sensitive vegetation.

Conclusion

Controlling vetch requires choosing the right herbicide based on your specific needs. Whether you prefer a selective or non-selective herbicide, products like Roundup, 2,4-D, and Garlon 4 offer effective control. By understanding your specific situation, you can select the herbicide that works best for your yard or field and get rid of vetch for good.
