The Poison Hemlock belongs to the carrot edible family. Each part of the plant is toxic to human beings and animals. The plant is small and has a white flower that grows in an umbrella shape.
The most toxic parts of the poison hemlock are the seeds and roots rather than the foliage. You can get poisoned by consumption, inhalation, and direct contact with the skin. For that reason, protect yourself by wearing a face mask and hand gloves while using herbicides.
However, if you know how to deal with poison hemlock which is using chemical herbicides, always read the instructions that the manufacturer gives, as well as be informed about the amount, the spraying conditions, and wear protective equipment. The best time to avoid using herbicides is when the forecast shows rainy or windy days.
Early diagnosis is always preferable since they can be removed with hands with the right protection.
The Top 5 Bet Herbicides for Poison Hemlock
1. Weedtrine D Herbicide- Best Aquatic
Weedtrine D is a lifesaver herbicide for residentials that live near lakes. The product is made for a wide range of weeds that are found in ponds, pools, fountains, and lakes. Do not apply any type of other herbicides that aren’t specified for aqua use.
Any floating weed below or above the water will be eliminated including the duckweed in a non-violated way.
Bear in mind that it would be necessary to mix with surfactant. The application is done in a hand-held spraying method directing to the poison hemlock.
The product will show visible results for 1/4-1/2 acre pounds. You also encounter water restriction, it should be 3 days dependent on the application rate and 1-day restriction for livestock, and 3 days for ornamentals and irrigation landscapes.
Weedtrine D herbicide has 8.53% diquat dibromide and should look like clear water.
2. BioAdvanced Brush Killer- Most Versatile
As the name presents itself, the Bio Advanced is meant to get rid of 70 other types of weeds and brush with the special formula. In a 32 fl. oz, the herbicide kills even the toughest plants, and the best part above all is seeing the results in the period between 1- 6 weeks.
Apply BioAdvanced along fences, cabins, trails, and wooded areas that are hard to pull with hands. The efficiency won’t fade even though after 4 hours of watering.
The concentration formula mix depends on the size and what you want to kill because it can kill even stumps.
For example, for a pump-style tank, you should apply 4 fluid oz and fill it with 1 gallon of water, which will treat 500 square feet. For the dial-style hose, the sprayer applies the same 4 fl. oz. and spray backward. If you want to get rid of stumps, use full power and don’t dilute.
3. Roundup Concentrate- Best Fast-Acting
Shout out to my impatient gardeners that want to see results in a short period of time. By using Roundup Concentrate, you can see the visible reaction in 24 hours. The manufacturer guarantees to kill the weeds from the root once and for all.

What’s Important to Know When Buying a Herbicide for Poison Hemlock?
Herbicides contain chemical ingredients that can fight back the toxicity if you follow the given instructions. Here is important information you need to know regarding herbicides:
- Check the weather before spraying and avoid if the forecast shows rainy or windy days, you need warm and sunny days for application.
- It’s recommended to wait for 2 weak to cut spray after applying herbicides.
- Don’t think that the more herbicide the better result, this only will hurt your pocket and waste your effort.

- In the first year, apply herbicides in Fall, and in the second year, spring times are ideal. Don’t wait for the poison hemlock to grow larger.

Avoid applying herbicide for poison hemlock that stands in the water unless the manufacturer has mentioned “aquatic use” on the label.
Here you have 2 control options for poison hemlock
- Manual Approach- for small undesired pests, you can just remove them by using your hands but dig deeper to get rid of the root as well, we don’t want the weed to come back, do we?
- Cultural Approach– pursue the disturbed area regularly by checking seedlings that become visible in the soil. Early prevention is always easier.
- Chemical Approach- a high concentration of glyphosate (41%) can be used for spot treatment or whole application.
- Spot Treatment- you don’t have to apply thoroughly, use herbicides only to spot treat.
