Neudosan is a an insecticidal soap made from potassium salts of fatty acids selected for their insecticidal effect for the control of adult, larval and nymph stages of pests. Neudosan can be applied up to a few hours before using beneficial insects as once the spray has dried there is no risk towards beneficial organisms. Organically certified for EU and NOP farming standards.

Mode of Action

After spraying with Neudosan inscects quickly die. The active ingredient disrupts the cell structure of soft-bodied insects causing the cell contents to leak out. The pest dehydrate in the spray liquid while also damaging the pests respiritory organs. In contract to other insecticdes, which attache the nervous system of insects, the dead pests remain attached to the leaves for a short period before the wither and drop off.

  • Neudosan breaks down to available fertiliser for the plant
  • Neudosan is registered for organic use and can be used in an IPM approach
  • Little persistance on the crop
  • Neudosan can be used up till the date of harvest

Ensure thorough wetting of plant including the under-side of leaves. Repeat treatments when necessary.
Spray Neudosan when temperatures are cooler and humididty is higher for improved efficacy.


Neudosan has been found to be compatible with most commonly used fungicides, insecticides and fertilisers. Physical compatibility should first be checked by using the current proportions of products in a small jar test. Growers should then test tank-mix combinations for phytotoxicity on a sample of crops prior to use.


Store in a cool, dry place in the original sealed container.
