#1. Roundup Poison Ivy Plus Tough Killer – Best For Quick Result
- Dimensions: 2.43 x 4.75 x 11.19 inches
- Weight: 2 pounds
- Volume: 32 oz
- Coverage: 1500 sq ft
This Roundup Poison Ivy Killer Bottle is indeed an overnight solution! This highly concentrated formula works fast because it combines two powerful brush-killing ingredients to kill even the most stubborn weeds. To be specific, the active ingredients are Glyphosate and Triclopyr, accounting for 18% and 2%, respectively.
Glyphosate can impair the protein formation of plants, while the other mimics auxin – a growing hormone in weeds. By generating excessive hormone, Triclopyr triggers uncontrolled growth, thereby killing weeds. This combo, coming in a high percentage, guarantees to show results after 24 hours, covering 1500 square feet. All in all, you could expect a complete weed elimination in 4 weeks.
Moreover, this concentrated formula also allows this killer to eradicate unwanted poisonous plants. In addition to poison ivy, it can also eliminate other plants such as poison sumac and poison oak.
But while this has quick results, it comes along with a trade-off. If you do not use it carefully and pour too much, there is a risk that your backyard lawn will also die.
- Rainproof in 30 minutes.
- Results in 24 hours.
- Covers a wide area.
- Can kill other poisonous plants.
- There is a risk of damage to the lawn.

- Dimensions: 9 x 6 x 4 inches
- Weight: 2.31 pounds
- Volume: 32 oz
- Coverage: 500 sq ft (for 4-8 oz)
If you are dealing with not only poison ivy but many other nasty weeds, this is an option you should consider. The Southern Ag Brush Killer has the ability to eliminate hard-to-kill plants, perfect for controlling vines, woody plants, and broadleaf weeds around areas you don’t want.
The science behind its powerful potency is the Triclopyr content of 6.36%. As explained, this acid works its magic by disorganizing plant growth. But compared to the Roundup product, this candidate boasts a threefold amount of Triclopyr. You can imagine how potent it is to kill poison ivy and other stubborn weeds at once.
It is a concentrated formula, allowing you to make a few more gallons of solution after dilution. This recipe doesn’t discriminate much, so most plants will be removed, including poisonous plants.
However, because of non-discrimination, it can also kill flowers, lawns, or any other plants nearby. So be very careful when using it.
You’ll also have to reapply a few times to get rid of the poison ivy, although they will dry out and wilt with just the first application. To completely get rid of poison ivy in your yard, it will take a few weeks.
- Easy to use
- Can kill many poisonous plants, weeds, and even woody types.
- Affordable price
- Quick results in about 2 weeks
- May harm plants you grow nearby.
- Need to reapply many times.
03. Ortho 475705 GroundClear Ivy & Tough Brush Killer – Best For Convenience
- Dimensions: 5.5 x 9.5 x 12 inches
- Weight: 12.29 pounds
- Volume: 1.33 gallons
- Coverage: Spot treatment
The formula can be applied in large quantities without the need for dilution – it’s the ultimate choice for convenience! Ortho even offers you a wand so that you can attach it to the bottle and directly apply the solution. There is no room for pumping or bending.
The solution comes with a ready-to-use formula in a large capacity, so you can tackle a large area without the effort and time of dilution.
Moreover, you will not have to spend money using other products because this killer can handle up to 60 types of wild and poisonous plants.
After applying, it can resist rain for 2 hours, and weeds will wither within 24 hours. Its shelf life of up to 1 year allows you to save and use it many times.
However, the large capacity is sometimes also a drawback of this one. 1.33 gallons may be too much for small gardens or if someone just wants to test its effectiveness. Because if you choose this type of solution in those cases, it will lead to excess product and waste of money!
- Ready-to-use formula.
- Suitable for large gardens.
- Fast results in a day.
- 1-year shelf life
- Not suitable for small gardens as it might be too much.
Checking the capacity is essential in killing wild ivy, as it will get used up, and you need to make sure there is enough killer solution to cover the entire garden area.
Therefore, depending on the purpose of use and the area of your garden, choose the capacity. The 1-gallon type is suitable for large gardens, while the 32 oz will suit a small area or case you want to experiment with that killer.
The two main types of formulations you can find are concentrated formulations and ready-to-use formulations. In addition, depending on the different brands, they will develop different types of formulas. But in general, the two types mentioned are the most common.
You won’t need to do anything with the ready-to-use solution. Just buy it and use it immediately in your garden.
Meanwhile, the concentrated type will require dilution before use, as in most cases, it will be too strong to use directly and might kill the surrounding plants. This variant is the preferred option as it seems effective in killing poison ivy and other hard-to-control weeds.
This is quite an important factor, and you must evaluate the effective time no matter what kind of herbicide formulation you are using.
It will tell you how long you have to wait to see its ivy-killing effect. And since this plant is quite nasty, you will probably need to get rid of it as soon as possible.
Most solutions are effective after 1 or 6 weeks after repeated application, but there are types that only need 24 hours to manifest results.
Consumers are flocking to use the quick-result type because it makes killing poison ivy less time-consuming and avoids the risk of infection.
This period is more important than you think. The weather can change suddenly, and you cannot predict whether it will rain or not. Especially when it comes to getting rid of poison ivy, you’ll want your solution to work for as long as possible.
Therefore, you will need to eliminate the risk of the solution being washed out by opting for a rainproof type. The time it takes to resist rain also affects the rate at which killer ivy results.
Usually, there will be 4-hour, 8-hour, and 12-hour rainproof types on the market. Those that give faster results are those with fewer hours of rain protection.
You only have to use your killer poison ivy once in a given season. So, too large a capacity can lead to an excess of killer ivy, and if it has a short shelf life, you will have to spend more money to buy a new one when it is needed.
Therefore, shelf life is also something you need to pay attention to. You also need to make sure there are enough killers to get rid of the poison ivy root. Buying too little is also not good.
Ivy solutions on the market today usually have a shelf life of 1 to 3 years. In most cases, the ready-to-use formulas will have a longer useful life.
This is the most popular formula for consumers to adjust the concentration at will. They are usually contained in smaller bottles than the ready-to-use type and typically have a capacity of about 16 – 32 ounces.
You will not be able to use them immediately after purchase without diluting them with any solution because they are too strong.
Once you dilute the solution properly, it turns into a usable weed killer in spray form. Typically, concentrated formulations will yield between 4 and 8 gallons of sprayable herbicide, which can cover an area up to 1,500 square feet.
However, one thing to note is that it should only be diluted to a certain extent.
It is best to follow the directions on the label. Even though the dilution gives you more herbicide, its potency will be decreased accordingly. So it will probably cover a larger area, but it will take more applications to destroy the poison ivy base completely.
On the other hand, if you don’t dilute it enough, it will be so strong that nearby plants will also die along with the poison ivy.
Contrary to concentrated formulas, ready-to-use ones live up to their name and can be used as soon as you buy them. No dilution or mixing with other solutions is necessary. You can use them to apply right away and don’t even need a sprayer.
Ready-to-use poison ivy insecticides are a great choice for those who love convenience. It’s because many brands will sell them with a spray nozzle so that you can spray immediately.
Many killers even have a battery-operated automatic sprayer, so you don’t have to spend any extra effort on the prep work.
The downside of these options is that they are often more expensive than concentrated formulations. Furthermore, you also cannot adjust the concentration of the herbicide in case it is absolutely necessary.
These products have been diluted to a ready-to-use level, so you cannot dilute them further, as this will only reduce the effectiveness of the product. And of course, you also won’t be able to make it more concentrated and strong.
Time Until Results
Different types of solutions will take a different amount of time to start showing results. Understanding this element of the product will help you not to be misunderstood about the use of the product.
Some treatments take a few days or weeks for you to notice them working. So, if you are in an emergency and hope to see poison ivy die as soon as possible, this is probably not a good choice.
In such cases, you can choose other herbicides that work faster instead. Some types only take 24 hours from the first application to take effect.
However, that does not mean that it will completely eliminate poison ivy that quickly. They still need a few re-applications to get rid of the plant to the fullest.
Total Area to Treat
Before choosing to buy a killer ivy, take a moment to consider the amount of poison ivy growing on your property, like how much space they cover. From there, you will know which option you need to choose.
Given that you’re only dealing with a modest amount of poison ivy on a small scale, it shouldn’t be too much of a problem, and you are spoiled with choices.
You can use ready-made recipes as they are usually small enough for you to treat your garden. You can also opt for the concentrated or the large bottles so that you can reapply many times to handle wild plants other than ivy.
However, if you need to treat a large area and lots of poison ivy, you won’t have that many options.
In this case, a concentrated formula that gives more gallons after dilution will be the way to go. Otherwise, you will have to spend more effort and money to buy more bottles.
