Woody vines, also known as climbing vines or perennial vines, can be difficult to control due to their persistent growth and ability to wrap around trees, fences, and other structures. These vines, such as poison ivy, kudzu, and wild grapevines, can quickly become invasive and wreak havoc on your landscape. Luckily, several herbicides are designed specifically to target and control these tough weeds.

In this guide, we will review the best herbicides for controlling woody vines, along with a buyer’s guide to help you choose the right product for your specific needs. Whether you need a selective or non-selective herbicide, the options below can help you tackle even the most stubborn woody vine infestations.

Best Herbicides for Woody Vines

1. Roundup (Glyphosate)

Roundup (Glyphosate) is one of the most well-known non-selective herbicides. It is highly effective at killing woody vines like poison ivy, kudzu, and wild grapevines by disrupting their ability to produce essential proteins. Roundup works best on actively growing vines and should be applied during the growing season for optimal results.

Roundup is ideal for large-scale infestations, as it can kill nearly any plant it contacts. However, care must be taken when using it around desirable plants, as it is non-selective and will harm other vegetation.

2. Crossbow Herbicide

Crossbow Herbicide is a powerful broad-spectrum herbicide that targets tough woody plants, including vines. It contains two active ingredients: triclopyr and 2,4-D, which work together to kill unwanted plants by disrupting their growth and nutrient intake.

This herbicide is highly effective against invasive woody vines like kudzu, poison ivy, and wild grapevines. It can be used on both young and established vines and is great for larger infestations in yards and forests.

3. Garlon 4

Garlon 4 is another selective herbicide specifically formulated for woody plant control. It contains the active ingredient triclopyr and is effective on a wide variety of woody vines, including poison ivy, wild grapevines, and Japanese honeysuckle.

Garlon 4 is ideal for treating large infestations and can be applied as a cut-stem treatment, making it perfect for more controlled applications. It is effective year-round, even in colder weather.

4. Triclopyr Ester

Triclopyr Ester is a selective herbicide that specifically targets woody plants and vines. It is especially effective on tough vines like kudzu, poison ivy, and Virginia creeper.

This herbicide can be used on large or small infestations and is ideal for treating vines that have grown up trees or fences. It works by disrupting the plant’s ability to photosynthesize, causing it to die off gradually.

5. Killzall Weed & Grass Killer

Killzall Weed & Grass Killer is a non-selective herbicide that is effective at killing a wide range of plants, including woody vines. Its active ingredient, glyphosate, works to disrupt the plant’s ability to produce proteins, leading to the plant’s death.

While it is highly effective for controlling vines and other weeds, Killzall should be applied carefully around desirable plants to prevent damage to them.

6. Stalker Herbicide

Stalker Herbicide is another selective herbicide that targets woody plants and vines. It contains the active ingredient imazapyr and is effective on a range of woody vines such as poison ivy, kudzu, and wild grapevines.

Stalker works by inhibiting the plant’s growth processes, making it a great option for persistent vine control. It can be applied to both cut stems and foliar applications for best results.

7. Amazapyr Herbicide

Amazapyr Herbicide is another effective option for controlling woody vines. Like Stalker, it contains imazapyr and is ideal for treating invasive species like kudzu and poison ivy.

This herbicide is a great choice for tough vines that are difficult to control with other products. It provides long-term results, making it an ideal choice for ongoing vine management.

8. Spectracide Weed & Grass Killer

Spectracide Weed & Grass Killer is a fast-acting, non-selective herbicide that effectively kills woody vines and other weeds. It works by rapidly dehydrating the plant, causing it to wither and die.

Ideal for spot treatments, Spectracide is a great option for smaller infestations or vines that have grown along fences and walls. Its fast action ensures visible results within hours, making it convenient for quick vine control.

9. Ortho GroundClear Weed & Grass Killer

Ortho GroundClear Weed & Grass Killer is a fast-acting, non-selective herbicide designed to kill woody vines and other unwanted plants. It kills roots on contact, making it effective for long-lasting control of persistent vines.

This product is a great option for large-scale infestations, as it prevents re-growth by targeting the root system. It also provides effective results within hours of application.

10. Southern Ag Crossbow Herbicide

Southern Ag Crossbow Herbicide is another highly effective product for controlling woody vines. It works on both herbaceous and woody plants, including poison ivy, kudzu, and wild grapevines.

Crossbow is ideal for treating large infestations and is effective on a wide range of plant species. It is easy to apply and provides long-lasting control.

Buyer’s Guide: Choosing the Best Herbicide for Woody Vines

When selecting an herbicide for woody vines, consider the following factors:

1. Selectivity

Consider whether you need a selective herbicide, which targets only the vines without harming surrounding plants, or a non-selective herbicide that kills all vegetation. Products like Garlon 4 and Triclopyr Ester are selective, while Roundup and Killzall are non-selective.

2. Application Method

Some herbicides can be applied directly to foliage, while others work best as cut-stem treatments. Be sure to choose a product that matches your preferred method of application.

3. Type of Vines

Different herbicides are effective against different types of woody vines. For example, Roundup is effective against many vine species, while Garlon 4 is particularly useful for poison ivy and kudzu control.

4. Speed of Action

Some herbicides work quickly, while others may take longer to show visible results. If you need fast results, look for products that offer quicker kill times, such as Roundup or Crossbow.

5. Safety and Environmental Impact

Choose herbicides that align with your environmental goals. If you are concerned about non-target plant damage, consider using selective herbicides that are more targeted in their action.

6. Cost

Evaluate the price relative to the size of the area you need to treat. Larger areas may require larger quantities of herbicide, so be sure to factor this into your decision-making process.

Conclusion

In conclusion, the best herbicides for woody vines depend on the type of vine you are dealing with, the application method you prefer, and the specific needs of your landscape. Roundup and Crossbow are excellent all-around options, while Garlon 4 and Triclopyr Ester are specifically formulated for tough woody vines.

Regardless of which herbicide you choose, always follow the manufacturer’s instructions and apply during the appropriate growing season for best results. With the right herbicide, you can effectively control woody vines and prevent them from taking over your landscape.

By considering factors such as selectivity, application method, and environmental safety, you’ll be well-equipped to tackle even the most stubborn woody vine infestations.
