Buyer’s Guide


Weeds are plants that compete with our ornamental plants and grass for water, light, and space. They can also harbor diseases and pests that can harm our other plants. By removing them, we give our other plants a better chance to thrive.

Roundup Poison Ivy Killer is one of the most popular weed killers on the market.
It’s available in both ready-to-use and concentrated forms, so you can choose the option that best suits your needs. It’s also relatively affordable, making it a great choice for budget-conscious gardeners.

Poisonous Principles

Weed killers are created to kill plants by targeting specific growth processes unique to plants. These include photosynthesis, respiration, cell division, and so on. Roundup’s main ingredient is glyphosate, which inhibits an enzyme found in plants called EPSP synthase. The elongation of serine, using a glutamate/serine (EPSP) synthase, leads to the synthesis of phenylalanine, tyrosine, and tryptophan (aromatic amino acids). By inhibiting EPSP synthase, glyphosate prevents plants from producing amino acids, and as a result, they eventually die.

Poisonous Principles

There are a few things to think about before employing Ivy Killer, despite its apparent safety and effectiveness.

The first is that glyphosate is classified as a non-selective herbicide, which means it kills all plants that contact with it. This includes not only weeds, but also desirable plants like flowers, shrubs, and trees. If you’re not careful when applying Ivy Killer, you could unintentionally damage or kill your other plants.

Second, glyphosate is a systemic herbicide, which means it is absorbed by the plant and transported throughout its tissues. This means that if you apply it to the leaves of a weed, the glyphosate will be taken up by the roots and stem as well, causing the entire plant to die. This can be beneficial if you’re trying to kill a particularly pesky weed, but it also means that Ivy Killer can easily contaminate other areas of your garden if you’re not careful.

Finally, glyphosate is a persistent herbicide, meaning it remains active in the environment for long periods of time.

First Aid

If you’ve been exposed to any poison of the weed clean the afflicted region with soap and ice water as quickly as possible. This will help remove the urushiol oil from your skin and prevent further exposure. You can also use a commercial Poison Ivy Wash, like Tecnu. If you don’t have access to soap and water. Apply calamine lotion or hydrocortisone cream to soothe the burning.

Urushiol can cause an allergic reaction when it contacts your eyes, skin, or mucous membranes.

The reaction usually starts within 12 to 48 h following exposure.

Poison ivy usually grows as a vine or shrub in wooded areas across North America. The plant has three glossy green leaves that grow in clusters of three. The center leaf has a longer stem than the two side leaves.

Poison ivy vines can grow up trees or on fences. The plant produces small greenish-white flowers in the spring and small white berries in the fall.

Cultural Control Methods

The most effective approach to control the spread of poison ivy is by utilizing cultural management techniques. This includes things like removing the plant from your property, mowing regularly, and pulling up any new plants that appear.

Cultural Control Methods

If you have pets or small children, it’s important to keep them away from poison ivy plants. Teach them to identify the plant and make sure they know never to touch it. [1]

Poison ivy can be a difficult weed to control, but hopefully these tips will help you get rid of it for good.

Herbicide Control Methods

The two main types of herbicides are post-emergent and pre-emergent. Post-emergent herbicides kill existing plants, while pre-emergent herbicides prevent new plants from germinating. Roundup Poison Ivy Killer is a post-emergent herbicide that contains the active ingredient glyphosate. Glyphosate kills plants by inhibiting the production of three enzymes essential to plant growth.

While it is effective at killing weeds, it has some drawbacks. First, glyphosate is a non-selective herbicide, which means it will kill any plant it comes in contact with – not just weeds. This can be a problem if you accidentally spray your lawn or garden. Second, glyphosate is a broad-spectrum herbicide, which means it kills a wide variety of plants – not just weeds. This can be a problem if you want to kill only certain types of weeds. Finally, glyphosate is a persistent herbicide, which means it remains in the environment for a long time. This can be a problem if you are concerned about the environmental impact of herbicides. [2]


Ivy Killer is available in a variety of sizes, from small bottles to large containers. The size you need will depend on the size of the area you need to treat.

Small Bottle: covers up to 16 square feet

Large Container: covers up to 320 square feet

The coverage indicated on the label is based on the amount of glyphosate in the product. The higher the concentration of glyphosate, the more coverage you will get. Roundup Poison Ivy Killer is available in concentrations ranging from 18% to 41%.

18% Concentration: covers up to 40 square feet

41% Concentration: covers up to 200 square feet

When using any herbicide, it is important to follow the directions on the label. Failure to do so can result in injury or damage to property.

Solution Type

Roundup Poison Ivy Killer is a post-emergent herbicide, which means that it’s designed to kill weeds that have already sprouted up. It’s not effective as a pre-emergent, so it won’t do anything to prevent new weeds from germinating.

This can be both a pro and a con, depending on your particular weed situation. If you’re dealing with a lot of existing weeds, then it can be very effective at getting rid of them quickly. However, if you’re trying to prevent new weeds from growing in the first place, you’ll need to use a different product.

Solution Type

Another thing to keep in mind is that Ivy Killer will only kill the plants that it comes into contact with. So, if you’re trying to kill a weed that’s growing in between cracks in the sidewalk, for example, you’ll need to be very careful not to get any of the herbicide on the surrounding concrete.

If you’re dealing with poison ivy, this product can be very effective at getting rid of it. However, if you’re trying to kill more common garden weeds, there are probably better options out there.

Effectiveness Time

Roundup Poison Ivy Killer is a fast-acting herbicide, which means that it will start working on the weeds almost immediately after you spray them. However, it can take up to two weeks for the weeds to die completely.

If you don’t mind waiting a few days for the results, this product can be very effective.

Rainproof Time

Roundup Poison Ivy Killer is rainproof, which means that it will still be effective even if it rains shortly after you spray it. This can be a pro or a con, depending on your particular situation.

If you’re trying to kill weeds in an area that tends to get a lot of rain, this product can be very helpful because you don’t have to worry about the rain washing it away before it has a chance to work. However, if you’re trying to avoid getting the herbicide on other plants or surfaces, rainproofing can make things more difficult.

Shelf Life

One of the questions we get asked a lot is how long Ivy Killer lasts. The answer depends on a few factors, but the most important one is how you store it. If you keep it in a cool, dry place, it can last for years. But if you store it in a hot, humid environment, it will only last for a few months.

Another factor that affects shelf life is how often you use it.

If you use it once a week, it will last longer than if you use it every day. And if you don’t use it at all, it will last indefinitely.

So those are the two most important factors to consider when determining shelf life. But there are other factors as well, such as the type of container it’s in and the amount of exposure to light and air.

Concentrates vs. Ready-to-Use Sprays

Ivy Killers comes in two forms: concentrates and ready-to-use (RTU) sprays. The biggest difference between the two is that RTU sprays are pre-mixed with water, while concentrates need to be mixed with water before use.

If you’re trying to decide which one is right for you, it really depends on your needs. If you have a large area to treat, concentrates will be more cost-effective since they can be diluted with water. On the other hand, if you have a small area or just want the convenience of a RTU product, an RTU spray might be a better option. [3]

Down-to-the-Root Elimination

Glyphosate is a systemic herbicide that travels down to the roots of plants to kill them. This means that, unlike other weed killers which only kill the top of the plant. One advantage of this is that you won’t have to worry about re-spraying your yard every few weeks to keep poison ivy at bay. Some people argue that this could also be seen as a disadvantage.

Down-to-the-Root Elimination

It’s important to be very precise when applying Ivy Killer and to avoid getting any on other plants. Ivy Killer kills the roots of plants, it could potentially make your soil less fertile.

If you’re planning on growing any plants in the area where you’ve applied Ivy Killer, you might want to consider adding some extra fertilizer to the soil.
