What kills fox tail weed?

Question

have used very strong mix of farmers round up and this has killed everything!! gave foxtails another dose to see if it would kill the grown weed it didnt even touch it!!

i think i have the right name for the weed?,it is a lime green weed with stem and loads of needle like things growing off the stem and has a long tap root wich makes it difficult to dig up

Answer 1

is it not horsetail?...I have it too...it has been around a very long time apparently..

Answer 2

Not an easy one this as mares tail is a very hard weed to eradicate.

The leaves of this plant are waxy so the weedkiller does not adhere to them, you need to bruise them first. Either walk on them or whip them with a thin twig in order to break the stem.

Now when you apply the weedkiller it will get into the plants system and hopefully kill it for you. It will require more than one application though.

Use a Glyphosate based product as this will biodegrade on contact with the soil and not taint it.

You can replant after 4 weeks. If you would rather not pour the weedkiller onto the plant you can sponge it on but still bruise the plant.

Hope this is of help

Answer 3

only way I know is to cover the ground with black plastic for about 7.......yes seven years. Its very very very hard to get rid of it.

Answer 4

It's almost impossible to kill. The roots can go down 4 feet or so, and the tough leaves resist the penetration of pesticides very well. Horsetails prefer poor soil, so improving your soil quality by adding lots of horse manure and cultivating the ground will help. The best thing is to keep pulling them up. They will regrow, but eventually it will weaken them. If they're in the lawn, mow regularly.

Glyphosate (Roundup) will also weaken them, but it's best to strim them down first, as the weedkiller can penetrate the cut stems better. Again, they will regrow, but repeated applications will eventually force them into submission.
