Efficacy is high
for an eco-friendly product.
It works through contact and
it is non-systemic
i.e. it doesn’t go with the sap in the plant and
it doesn’t go with the rain to the ground water.
all ingredients are readily biodegradable.
Comparing to an old, “chemical” weed and moss killer
Through 6 years and during different seasons 25 scientific tests have been performed in the UK and Scotland by GEP (Good Experimental Praxis) Authorised institutes.
These tests have been performed in accordance with acknowledged standards:
‣ Evaluation through 28 days.
‣ Evaluation of a range of doses.
‣ Evaluation of effect on a number of different weed species.
Effect on 30 different weed and moss species have been evaluated.
The recommended dose is the result of these efficacy trials: Max. 10 cl. of the ready to use dilution per m2.
In these tests the NWS formula has been compared to well known ”chemical” weed killers. The average control percentage of the NWS formula is 93%.
