Kudzu is a viney plant that grows very rapidly. It is known to take over large objects such as cars and buildings. While it is resistant to most safe chemicals, some herbicides like Crossbow and Garlon have proven effective in killing it. Some people also suggest using diesel fuel to kill the plant, but this is not environmentally friendly.

What You'll Learn
Garlon and diesel fuel mixed together can kill kudzu
Kudzu is a hardy perennial vine, native to Japan, that can grow very rapidly. It is resistant to most "safe" chemicals, although some herbicides like Transline (clopyralid) and 2,4,D have some effect. However, these chemicals need to be applied frequently and may not be suitable for everyone.
Garlon and diesel fuel can be mixed together to kill kudzu. According to some sources, a mixture of 20% Garlon 4 and 80% diesel fuel can be effective in killing kudzu. This mixture has a 4-hour half-life at ambient temperature, which means it breaks down quickly and may not be as harmful to the environment as other chemicals.
It is important to note that diesel fuel is not a selective herbicide, meaning it can kill any plant it comes into contact with. Therefore, it should be used with caution and only on the targeted plants. Additionally, the use of any chemical herbicide should be carefully considered, as they can have negative environmental impacts and potential health risks.
When using Garlon and diesel fuel to kill kudzu, it is recommended to choose a warm day without rain and wind but with rain expected in a day or two after application. This helps ensure that the treatment is effective and minimizes the risk of unintended spread. It is also important to pull off any vines from fences or structures before treatment to prevent the kudzu from taking over other areas.
While Garlon and diesel fuel can be effective in killing kudzu, it may not be a long-term solution. Kudzu can grow back after treatment, so periodic control and maintenance are necessary to keep it from getting out of hand. Other methods, such as using goats to eat the kudzu, or herbicides like Crossbow or Roundup, can also be considered as part of an integrated approach to managing this invasive plant.

Crossbow herbicide mixed with diesel fuel
Kudzu is a viney plant that grows rapidly and is known for taking over the world. It is resistant to most "safe" chemicals, although 2,4,D has some effects if used frequently. It is also oblivious to both chemicals and pests. While there are no specific details about using Crossbow herbicide mixed with diesel fuel for kudzu, some sources mention the effectiveness of using herbicides like Transline herbicide (clopyralid) and Garlon with diesel fuel.
One source mentions that Garlon 4 can be mixed with 20% Garlon 4 and 80% diesel fuel. Another source mentions that a mixture of 3 parts diesel to 1 part Remedy/Garlon (which are the same) has been successful in basal bark applications for treating locust trees.
Additionally, a general mixture of herbicide and diesel fuel is mentioned as effective. One source suggests using liquid soap, diesel fuel, and your preferred herbicide to kill kudzu. However, it is important to note that diesel fuel is not recommended for foliar spray applications unless it is for basal bark treatment, which requires a meticulous tree-by-tree application.
While herbicides and diesel fuel can be effective in killing kudzu, it is important to exercise caution and follow instructions on product labels. Additionally, other methods such as mulching, using goats or cows to eat the plants, and mechanical removal with bulldozers have also been suggested for kudzu elimination.

Mulching the plants with concrete blocks
Kudzu is a viney plant that grows rapidly, taking over the world. While diesel fuel mixed with Garlon or Roundup is said to be effective in killing Kudzu, mulching the plants with concrete blocks is another way to deal with this invasive plant.
Concrete mulch will not add nutrients to the soil as organic mulch does. However, it can be used to prevent soil erosion, loss of moisture, and unwanted weeds from growing around plants. It can also bring a modern look to plants while increasing property value.
When using concrete mulch, it is important to consider the impact on the pH level of the soil. Concrete contains limestone (calcium carbonate), which can increase the pH of the soil to high alkaline levels, making it less ideal for certain plants. To mitigate this, ensure that the concrete is washed to remove dust that can be carried into the soil by rain. Applying concrete mulch at a depth of 1-2 inches, 2 inches from the base of the plant, is recommended.
For young Kudzu plants, applying a heavy mulch of concrete blocks can be effective. While this may cause a temporary setback, the resilient Kudzu plants will likely rebound with increased vigour. Therefore, while mulching with concrete blocks may provide a short-term solution, it is not a foolproof method for eradicating Kudzu.
In addition to concrete blocks, other inorganic mulching materials such as rubber nuggets or plastic sheeting can be used. These materials should be replaced when they become worn down or ineffective due to weather conditions. It is also important to note that inorganic mulches do not improve the soil in the same way that organic mulches do through decomposition.

Using goats to eat kudzu
Kudzu is a hardy, viney plant that grows very rapidly. It is native to Asia but has been problematic in the southeastern United States for decades. The plant's vines grow rapidly over trees and shrubs and kill them by heavy shading.
In July 2011, the Catawba Lands Conservancy (CLC) partnered with the Garden and Clean Water Management Trust Fund to conserve the 77-acre Seven Oaks Preserve, which had been invaded by kudzu. As part of this initiative, 50 goats were introduced to the preserve to eat and clear the kudzu. The goats took about five weeks to graze and eat 10 acres worth of kudzu. This method of using goats to control invasive kudzu is environmentally sensitive and effective because kudzu is high-quality fodder for goats and other grazing animals.
Before using goats to eat kudzu, it is important to consider the scale of the infestation and the number of goats required to clear the area effectively. In the case of the Seven Oaks Preserve, 50 goats were sufficient to clear 10 acres of kudzu in about five weeks. However, it is worth noting that kudzu can grow rapidly, especially in wet weather, so it is essential to monitor the affected areas and act quickly to prevent the infestation from spreading.
After the goats have eaten the kudzu, it is necessary to assess the soil and tree conditions for any damage and erosion. To prevent kudzu regrowth, targeted herbicides can be used to completely kill the kudzu's extensive root system. While goats can be an effective method for kudzu removal, it may not be practical or feasible for all situations, especially if the infestation is widespread or in hard-to-reach areas. In such cases, other methods, such as herbicides or mechanical removal, may be more suitable.

Using other herbicides like Roundup or Transline
While diesel fuel mixed with herbicides like Garlon 4 or Roundup can be used to kill kudzu, there are other herbicides that can be used effectively without diesel fuel. These include Transline (clopyralid), which is a herbicide that only kills legumes, so when applied under the label, the only non-target kill is legumes such as redbud, lespedeza, and mimosa. According to a user on a forum, Transline required two treatments a few months apart, and in one case, a third treatment was needed.
Roundup (glyphosate) is another herbicide that can be used to kill kudzu. It is mixed similarly to Crossbow, another herbicide that has been successful in killing kudzu. However, it should be noted that Roundup will only kill the parts of the kudzu that it touches, and a single annual treatment is not sufficient. A better approach is to treat kudzu in late spring or early summer after the leaves have fully expanded and then apply a second treatment in late summer or early fall to the new growth.
Other herbicides with the active ingredients glyphosate and triclopyr can also be used for kudzu control in residential settings. These must be carefully applied according to label directions to prevent potential damage to nearby desirable vegetation, including trees, shrubs, flowers, grasses, and vegetable gardens. The optimal timing for foliar treatment is late summer or early fall, and the safest approach is to cut any kudzu vines just above the ground and immediately treat the stem with one of the recommended glyphosate herbicides using the cut stump method.
