Morning all,I'm in the process of creating a new herbaceous border for a customer and need to eradicate a substantial area of ground elder which is along one edge of the border to be.My question is: Does anyone have a preferred chemical combination for killing ground elder effectively? Ideally a spray now killing 90% and another in spring to finish it off. I commonly use glyphosate but wondered if anyone perhaps had a tank mix that was more effective? I was wondering about Roundup and Grazon?Thanks,Tom

  • I find Triclopy (available as Garlon or Blaster) far more effective than Glyphosate on groundelder........... one application usually kills it for good if there's a good bit of leaf on it.  60ml in 10 litres and saturate the foliage.

    I've got about 100sqm of the stuff to get rid of so glad you asked this question 

  • really tricky stuff to get rid of one border I do regally and have done so for 15 years and still have not got rid of it completely glyphosate with a wetting agent early spring before the plants start growing  the elder appears a week or two before the plants

    Thanks Graham for the direction towards Garlon, I'll give that a try. As a side point to this thread, does anyone know if for using ecoplugs I need an addtional qual to PA6? I know the official coding is PA6D but does normal PA6 cover this?

    Thanks again

      I did my PA1/PA6 recently and opted to do the Eco plugs and stem injection while I was there as they are now separate, but if you've had your PA1/PA6 a while then your covered mate...

        I passed my PA6 in Feb 2015. Not sure how that relates to when they separated them.

          I did mine January this year and it had been separated, yours will be a close call, but I know change was very recent so you may be clear, I'd probably just check with Progreen mate.

    Blaster every time - the younger the ground elder plants the better - if older pays to cut them back and then treat the re-growth.

  • I find a systemic chemical called Gallop works fine especially for ground elder.

    I've had really good results by clearing it with a hoe, waiting for re-growth and then using Hammer on the young leaves. Some jobs its eradicated it in one hit, other jobs, two.
