NEUDOSAN® natural spray against aphids
Plant protection product for ecological gardening
NEUDOSAN® is a natural spray against aphids and other sucking pests, working quickly and without chemical residues. It contains potassium salts of natural fatty acids that disrupt the insect’s outer surface, leading to its death within a few hours. The product is gentle on plants, bees, and beneficial organisms, making it suitable for use in greenhouses, winter gardens, or even living spaces. Fruits and vegetables can be consumed immediately after application, as the product has no pre‑harvest interval.
-
What it can do: Eliminates aphids, whiteflies, spider mites, and other sucking pests by direct contact. Works quickly, is ecological, and safe for beneficial insects.
-
What it cannot do: It does not act systemically – it only works where the spray directly hits the pest. It does not prevent new infestations, so treatments need to be repeated.
-
What to use instead: In cases of heavy or repeated infestations, other natural products (such as Rock Effect, based on natural oils) or selective insecticides with longer residual activity may be more effective.
NEUDOSAN® contains 51% potassium salts of natural fatty acids (commonly known as “soap salts”). These substances disrupt cell membranes and the waxy cuticle of insects, causing dehydration and respiratory failure. The effect is purely contact‑based – it does not penetrate into the plant or the pest’s tissues. The product degrades quickly in nature and leaves no residues. It is effective against aphids, spider mites, whiteflies, flea beetles, and other sucking pests on vegetables, fruit trees, berries, strawberries, and ornamentals. The product is certified for use in organic farming.
-
Application: spray until runoff, covering both upper and lower leaf surfaces; dilute to a 2% solution (20 ml per 1 l of water). Apply at the first signs of infestation, up to 3 times at 7‑day intervals. Effective only on directly treated pests.
