Persistence is required but I've had success with Kurtail.

There were a large number of threads on this subject, hence comments recently that may be worth reading.

Had good success with Round up 360. The trick is to damage the plant before spraying or the weed killer can't penetrate it. I just rub the plant between my hands until bits start to break off. Spray and then usually follow up with another spray session in a week or so.
Morning, it depends whether you want to just burn off the top growth, or if you want to kill it down to the root. If you wish to just burn off top growth then use a product called Whippet which is available in a 500ml container for £27.90. If you want to kill it down to the roots then use a product called Broadshot which comes in a 1L container and is £35.40. Broadshot is also selective so safe to use in grass.
Both will offer great results.

Let me know if you need any more information.

I would go about it with a bamboo cane to bruise all the stems first, then hit it with your selected weedkiller, the stems are tough so need bruising to allow penetration of the weedkiller. you do look a bit of a plank beating it like Basil Fawlty, but it does work better trust me.
ive used Kurtail /Whippet on a few jobs now the last 2/3 years.
im just waiting for Broadshot results..
You definitely don't need to bruise the stems if you use Kurtail - its been proven to work on horsetail over many years - with a bit of persistence to reduce numbers successfully, as Simon says. One point to note is you gain more efficiency with glyphosates (and Kurtail) by using Kplus water conditioner if you are in a hard water area - to minimise the problems of 'locking up' or reducing the actives in these formulations.
Kaskara has the same active ingredients as Broadshot

Hi Ben,
I agree that weeds treated with a translocated weedkiller can benefit from a good thrashing due to their method of entry into the plant and they tend to have a slower speed of kill - particularly at this time of year when leaves are tough and waxy. An alternative for some species of weed is to use an appropriate adjuvant.
Kurtail is a contact weedkiller and inhibits the production of growth proteins where it touches the plant - leading to death of the growing point.
Horsetail is a botanical throwback so relies on an extensive network of rhizomes and a heavy silica outer layer. Glufosinate ammonium needs no physical 'help' - this active ingredient is known to penetrate the outer layer successfully on a healthy, actively growing plant. We have tried many different methods over the years and bruising makes no difference to the speed of death of horsetail when using glufosinate ammonium.
Kind regards,
Louise
