Neudorff Glyphosate free Weedkiller Where to Use

This ready to use Glyphosate free Weedkiller controls mosses and algae on natural paths and on open areas around trees. It is most effective when applied on small actively growing weeds and can be used under shrubs and trees as it doesn't harm the woody parts of the plants.

It can be used on natural surfaces not intended to bear vegetation and permeable surfaces overlying soil.

It can also be used on gravel other permeable surfaces where no vegetation is wanted including around the base of walls or sheds and on any waste ground not intended for growing.

Do not use in impermeable surfaces such as concrete, tarmac or paved areas where the weedkiller solution might run off onto adjacent land or into drains or gutters.

How to Use the Neudorff Glyphosate free Weedkiller?

Apply undiluted liquid directly from the bottle by spraying. Ensure that the target plants are thoroughly wetted.

Do not directly spray or allow spray to drift onto cultivated plants as the weedkiller is designed to kill all green plant parts.

Do not spray in windy weather.

Ideally only use when weather temperatures are 15 degree celcius or highter

If it rains within 12 hours of treatment it can impair the effect of the product.

Mosses and algae on natural paths and on open areas around trees will usually be controlled by a single spray application but repeat applications may be applied at 3-4 week inteval if incomplete control is achieved or follwing regrowth.

  1. help. We are thinking of reseeding about 4 acres of silage ground, and have been told to burn off all the vegetation first. I dread to think of all the toxins in the amount of weedkiller we will have to use, and would really appreciate if you could give an advice on organic alternatives. Thanks in advance

    1. Hi Margaret,
      Got a brief email from you on this which I misunderstood.
      This organic weedkiller would certainly be a greener solution and should be fit for purpose considering that it is a non-selective solution (it will burn wherever you spray). Given that 1 acre is roughly 4,000 square meters and each 1 litre of concentrate covers 450 square meters you would need to order 35 to 40 litres in order to completely cover the whole 4 acre area. Ordering in 5 litre quantities would thus be the best value for money. You might however wish to order one litre initially to ensure you are satisfied with the job it does.
      Feel free to call us if you have any further questions.

  2. Is the ‘Irish Organic Weed Killer’ still available as link won’t allow me to purchase?

    Also, can you tell me if this product kills grass also?

    1. These listed Neurdorff ready to use 750ml bottles is the only certified organic weedkiller available in Ireland at present to the best of our knowledge. There used to be an Irish Organic concentrate but this product is no longer available.
