Why Compare?

This blog post is from a parent’s perspective who can’t decide what product to use. Tordon and RoundupRoundup are tree killers, but they have some essential differences useful for different scenarios. Let’s explore their similarities and differences, so you know when it’s best to use one over the other.

Both products contain herbicides that work by blocking a plant’s ability to manufacture proteins, leading to its death. They both also have nonselective action, meaning they will kill any vegetation in the area where they are applied while not being selective with what kind of plants it kills.

In contrast, there is a type of weed killer called an organic or natural herbicide (which you can learn more about here) that only destroys specific types of weeds and leaves your lawn intact!

Tordon contains picloram as well as dicamba for enhanced tree-killing power. These ingredients make tordon especially good at exerting broad-spectrum control on hawthorn trees, junipers, other trees, shrubs, and vines. Roundup contains glyphosate and other chemicals to make it effective against many plants, including kudzu vine and dandelion weed.

Now that you know the similarities between Tordon and Roundup, let’s explore their differences in use: tordon is typically used by homeowners for spot applications when they have a tree in their yard that needs removal but are hesitant because of the potential damage to their lawn – this is because tordon will only kill any vegetation within 50 feet (lineal) from where it was applied so your grass should be safe! In contrast, RoundupRoundup can also be used on weeds directly without damaging nearby plant life if appropriately diluted with water according to package directions.

Tordon’s superior tree-killing power and limited area of effects make it a better choice when you have an unwanted tree in your yard that needs removal. On the other hand, Roundup can be used for weed control without damaging nearby plants but has a relatively weaker effect on trees. It should only be used as a last resort if no other options are available to homeowners. They want their grass & flowers left intact too!

How To Use Tordon Tree Killer

Apply tordon according to the package directions if you’re looking for a quick fix. It’ll kill any vegetation within 50 feet of its application and won’t damage nearby plants (grass & flowers will be safe!). Step-by-step guide

Step 1: Put on clothes that are going to protect you. Also, put on eye protection and gloves.

Step 2: To cut a tree, use an ax to make cuts 2-3 inches deep. Keep the cuts evenly spaced at 2-3 inches apart. Cut around the tree at the height of 2-4 feet.

Step 3: Fill a tree injector or applicator bottle with the amount of Tordon recommended by the manufacturer. The amount will vary depending on the size of your tree.

Step 4: Inject the herbicide into the cuts on the tree. The recommended amount is around 1 to 2 milliliters per cut, depending on how big a cut you have. Apply enough to wet the cut areas; do not allow for any runoff.


We’ve now explored the similarities and differences between Roundup vs. Tordon as a tree killer so you can make an educated decision about which to use in different situations! For example, if your goal is to kill a tree while saving nearby plants, then tordon would be your best option. It will only affect vegetation within 50 feet of its application and won’t damage any other plants. In our review, tordon is the winner of the best tree killer.
