Mare's / Horse Tail

About Mare's Tail / Horsetail

The name "horsetail" is derived from the Latin Equisetum which translates as equus, meaning horse and seta which means bristle or hair. 

Horsetail is also known as marestail, mare’s-tail or Hippuris vulgaris and is an aquatic weed. Horsetail is a slender, tall weed commonly found in ponds or slow-flowing streams.

Where does Horse Tail grow? 

Horsetail prefers moist areas but is increasingly found on waste ground, in gardens and on non-cropped areas. It has a thick, silica-rich outer layer and small needle-like leaves. This can make it difficult to get sufficient spray into the plant to kill horse tail.

Is marestail/ horsetail harmful?

Horsetail is a poisonous weed if consumed raw due to the heavy content of silica in the weed. Grazing animals will usually avoid marestail but it can become more palatable as it dies.

Kill Mares Tail/ Kill Horse Tail

Repeated cutting will weaken the rhizomes in Horse Tail but is generally ineffective on its own in killing horse tail as it has a deep and spreading root system. Cultural control methods like digging can often make the problem worse because each broken root fragment can develop into a new plant by itself - multiplying the problem.

Treating horsetail with Kurtail Evo

Kurtail Evo is the new weed killer just introduced by ProGreen - the number one name in marestail control. Kurtail Evo will kill marestail or horsetail as well as other broad leaved weeds and grasses in about 10-14 days. You may need successive applications to control newly emerged weeds that grow from untreated roots. Weed control results can be made even more consistent by adding KPlus to the spray tank

Sprayed horsetail usually takes 1-2 weeks for the weed to show symptoms, but it will take longer to rot down and disappear, so be patient. Once it is black and dead it may be raked/ or cleared away. If you are looking to kill mares tail in a paddock it will eventually rot down and disappear. Then it is safe to graze on and bale for hay. Although the method of mares tail eradication sounds dramatic, there are no alternative products that can effectively control horsetail in grassland. Please note that all grass species will also be killed by Kurtail Evo

You can currently use a boom sprayer to apply Kurtail Evo. There are three pack sizes available to suit all the requirements of all users. ProGreen supplies Kurtail Evo in 0.5 L, 1 L and 5 L pack sizes There is no chemical effect on the soil and no residual effect from the treatment
