How To Identify Horseweed
When you have identified which kinds of weeds are in your lawn, you can plan how to get rid of the plant without killing it. First, you have to find the source of the plant. Identify which plants the main stem of this horseweed develops from. Then, you need to determine how much of the main stem is subjected and how much is protected .
Once the weed killer has completed its job, pour some water on the area where the weed killer was implemented. Then, use a sprinkler or a hose to water the grass in the lawn. This can keep the soil moist while it functions as a preventive measure against future plantings of Horseweed. If you live in an arid climate where water can become scarce, you may wish to think about using a livestock spray onto the horse grass in your yard. This will help protect the grass from other less drought-tolerant plants.
Ultimately, how to kill horseweed could be down to one thing: timing. It would be best if you killed the weed whenever you can since the root cause of the plant is extremely shallow, and it can be exceedingly tough to dig it out. If you can, try to dig it out in the spring before it could do any harm. This is because the plant generates a poisonous compound as part of its defense from grazing animals and humans. You can help by keeping animals away from the area.
What Are Horsetail Weeds
The horsetail weed family , closely related to the fern family, contains over 30 ancient species of plants. At one time, horsetail was the dominant plant on the earth and was said to have grown to a very large size. Today, there are two forms of this perennial plant.
One is known as scouring rush, and has no leaves but instead has hollow and jointed stems. At one point in time, this plant was not considered obnoxious and was actually used extensively. Early settlers used the stems of this horsetail plant to clean pots and pans. English cabinetmakers used the stems to polish wood.
The second type of horsetail plant has many slender, green, jointed branches around jointed and hollow stems. Its appearance resembles a horses tail and is sometimes called a mares tail. This horsetail was also used by ancient civilizations to stop bleeding and heal wounds.
Horsetail is a perennial, flowerless weed that can be very toxic to animals, especially horses, if eaten in large amounts. Horsetail spreads by spores that are carried by the wind. Horsetail can be found in ditches, around ponds, along roadsides, in fields, and sometimes even in the garden.
How To Kill Mare’s
06 July, 2011
Mare’s-tail is a common weed also known as horseweed. The plant is an annual that can appear in the spring or fall, reaching heights of 6 feet, with leaves that increase in size the farther down the plant you go. Some varieties of mare’s-tail are resistant to glyphosate, one of the most common herbicides. This resistance is especially prevalent in the central United States.
Pull up any existing mare’s-tail weeds in your yard by hand. Get up as much of the root system as possible. If the weeds are mature and do not come up easily, use a hand spade to dig them out.
- If the weeds are mature and do not come up easily, use a hand spade to dig them out.
Discard the weeds in the trash. Do not compost the weeds, because you may spread dormant seeds with the compost in the future.
Till the soil with a garden tiller at a depth of 12 inches. Tillage is the most effective method of mare’s-tail control.
Apply a metribuzin herbicide to any regrowth that appears the following spring. Follow application instructions on the package. Apply the herbicide when the mare’s-tail is 4 inches tall or less. Wait the instructed time for the herbicide to take effect, then till the soil again.
- Discard the weeds in the trash.
- Apply the herbicide when the mare’s-tail is 4 inches tall or less.

Things To Avoid When Killing Horsetail Weeds
Horsetail is a difficult weed to control. And some methods will make the problem worse.
You should avoid cultivating the soil to get rid of horsetail. It wont work.
Instead, youll spread bits of chopped up rhizome through the soil. Each part can produce a new plant, increasing the spread and giving you even more work to do.
If you do decide to cultivate the soil, make sure to clean your tools after to make sure there arent any bits of rhizome left on the blades. Otherwise you may end up spreading the plant to another part of your garden.
Best Management Practices For Marestail
1) Control fall-emerged marestailbefore the winter with a fall burndown. If fall seedlings are not controlled, they overwinter and are more challenging to control in the spring. If planting a cereal rye cover crop, 2,4-D and dicamba may be used.
2) Control all horseweed prior to cash crop planting. Effective POST options are limited, especially in soybean.
3) Use multiple effective herbicide modes of action . Vary MOAs in tank mixes and between applications. Using herbicides with different MOAs prevents selection of weeds resistant to certain herbicides like glyphosate or ALS.
4) Target marestail under 5 inches tall when they are most susceptible to herbicides. Scout early and regularly.
5) Include residuals at planting to prevent late-spring emerging horseweed plants.
6) Shade out spring marestail with winter annual crops or cover crops, narrow row spacing, or high seeding rates.
7) Hand-remove mature marestail before flowering, before it has a chance to produce and disperse its seeds.
8) Include corn or small grains in rotation, to increase herbicide options and compete with marestail for sunlight. Small grains and alfalfa also allow for mowing and harvesting as control options.

How Do I Get Rid Of Mares Tails In My Lawn
Pearl is a total weedkiller and will kill Mares tail, weeds and grass in about 7-10 days. It will kill the horsetail systemically, right through to the root and treated plants will not grow back. You may need to treat new plants that grow from untreated roots, but once sprayed they too will be completely controlled.
Cover Crops For Marestail Suppression In No
A high-biomass winter annual cover crop can suppress a high percentage of marestail in the spring. If it is left on the field after termination, it can also shade out marestail that emerges after cash crop planting. A vigorous species like cereal rye should be planted after fall harvest and allowed to grow for several weeks into the spring. This allows it to accumulate biomass so that it can function as a weed suppressive mulch that the crop is later planted into. In general, 4000 lb or more dry matter is necessary prior to termination, in order to actively suppress emerging weeds in the spring. Higher biomass can be achieved by earlier planting dates and later termination dates. Before planting cover crops for weed suppression, please contact Penn State Extension for more information, as results depend on various management decisions and individual farm factors.

Bees, bumblebees and butterflies love the plant. It is one of the most famous medicinal herbs. The wild plant is common in meadows and field margins. It is undesirable on lawns. How can it be successfully controlled?
Use Vinegar As A Natural Weed Killer
Vinegar is good at killing horsetail above the ground. But the normal table variety isnt strong enough to do the job. Instead, you need to get high-strength vinegar with an acetic acid concentration of around 20-30%.
Similar to chemical weedkiller, your results will be better if you first damage the plant by cutting the stems or crushing the leaves.
Vinegar is a contact weed killer. This means it can destroy the parts of the plant it touches. But it wont kill the roots. So the horsetail will re-grow.
However, destroying the growth above ground with repeated applications can weaken the plant. And if applied regularly over a long enough period it can cause it to die.
As useful as it is, using vinegar has a drawback:
The problem is that its non-selective. So it will kill any plants it comes into contact with. Making it difficult to spray on grass lawns or around desirable plants.

What Is A Noxious Weed
Of the approximately 250,000 species of plants that exist worldwide, only about 3% behave as weeds that we dont want in cultivated areas. And just a handful of these are what we call noxious, which isnt just a word that we made up. This is an official plant classification that we apply to a small number of plants that are so harmful that we need to destroy or contain them to limit their spread.According to the WSSA , a noxious weed is any plant designated by federal, state, or local government officials as injurious to public health, agriculture, recreation, wildlife, or property.
These arent garden-variety weeds. Just because crabgrass has stepped on your prize rose bed doesnt make it a bothersome weed for everyone. In your own garden or lawn, no one decides what a weed is except you. See what weeds tell you about your soil.
But think about the word noxious. Some synonyms for it are deadly, virulent, harmful, dangerous, toxic, environmentally unfriendly, poisonous, nasty, awful well, you get the general idea. Noxious weeds are a danger to our environment and the economy. They can take over entire ecosystems, destroy natural habitats, damage agricultural production, and cause losses worth millions of dollars. As they spread to natural areas, they harm wildlife and plants and can be impossible to eradicate.

Killing Horsetail With Salt
Adding enough salt to your soil will create inhospitable conditions for horsetail to grow. You can mix it with water and pour it over the infested area.
But this isnt a recommended way of dealing with the problem.
Why? Two reasons:
Firstly, although salt will kill horsetail it will probably leach into nearby areas of your garden, killing the plants there as well.
And secondly, because it makes the soil unsuitable for any plants to grow. And this can last for a long time. Preventing you from replanting the area.

Integrated Weed Management Strategies
Cultural Tactics: Competitive cash crops will delay or reduce germination, growth, and seed set of many weed species. For horseweed, the spring emergence window is ending or has already ended at the time of cash crop planting so efforts for control are better focused prior to planting. In some areas, where the horseweed germination window extends into the growing season, narrow row spacing can help the cash crop reach canopy more quickly and compete with young horseweed plants.
Crop rotation: is one cultural tactic that can impact horseweed density. Crop rotation provides the opportunity to diversify weed management tactics, preventing and combating herbicide resistance. Studies have shown that a soybean-corn crop rotation can reduce horseweed density compared to planting continuous soybean. Corn is typically planted earlier than soybeans so this rotation allows for herbicide application earlier in the spring while the horseweed plants are smaller residual herbicides applied to corn also prevent much of the spring emergence flush. There are also different herbicide options available for these crops.
With horseweed, repeated scouting is necessary because of the weedâs long, unpredictable germination periods and its ability to spread long distances. It can be easy to miss a flush of germination or a new infestation without repeated scouting.

Step By Step Guide To Controlling Horsetail / Marestailchemical Control Method
1. Remove dead marestail stems/stalks ideally in the winter months or alternatively early spring
2. Do not spray too early but wait until the horsetail is approximately 15 cm 20 cm high and looks like a small bottle brush
3. Spray using a herbicide such as Kurtail Evo onto to the weed. Spray on until the plant is fully covered with a fine or medium spray.
NB: Do not worry if the marestail is taller than 15 20 cm high, it can still be treated using a herbicide, but the level of control may not be as effective
Please note Kurtail Evo is a Total Weed Killer meaning it will control mares tail, as well as a wide range of other broad leaved weeds and grasses
4. The horsetail, marestail will usually take 1 2 weeks to turn brown, however it will take longer to disappear and be killed. The longer you can wait the better results you will get
Progreen Tip You can check if the plant is dead by breaking off a small piece of the stem near to the ground. If it is still green in the centre the plant has not yet fully died back
5. When the marestail is black and dead it can be raked and cleared away ideally burnt or put in a garden recycling bin. It is recommended that horse tail is not composted due to its ability to regrow from very tiny root particles
To get good control of marestail you need to be consistent and persistent.

Dogfennel Control: How To Get Rid Of Dogfennel
This page is a general dogfennel control guide. Using the products and methods suggested, you will get control of dogfennel. Follow this DIY guide and use the recommended products, and we guarantee 100% control of dogfennel.
Dogfennel is a tall summer annual or short-lived perennial weed that falls under the name Eupatorium capillifolium or dog fennel and thrives in poorly maintained south eastern to west yards, pastures, and gardens. Depending on the conditions of the turf this weed can grow to reach heights above 3 feet or reach full maturity as a short plant less than 6 inches. Despite the soft touch of the dogfennel leaves this plant secrets a sour and musty odor when crushed.
This broadleaf weed prefers thin terrain containing moist to wet areas, but does not do well in thick, established lawns. Once dogfennel has settled on your property it releases numerous seeds which will quickly suffocate other desired plants. This plant also contains a spreading rootstock that helps dogfennel to survive drought sites, such as Texas terrain.
The name dogfennel comes from this weeds use around the floor of dog kennels to ward off fleas and ticks. This worked, because dogfennel contains an alkaloid toxin, pyrrolizidime that is used in various insecticide products. If dogfennel is crushed then it produces a liquid secretion with the toxic alkaloid, which could cause liver damage. The liver will clog and begin to retain fluids if consumed in large quantities that may cause death.
