Neudorff Concentrated Black Soap 1l

Concentrated black soap is ideal for cleaning numerous surfaces such as tiles, paving, slate, stone, wood, and leaves soiled by aphids and scale insects... It is multi-purpose, and it can be used in the home and garden, including for controlling certain insects and diseases. Packaged in a 1L container, it will prepare 50 L of solution for spraying.

This concentrated formula contains 30% potassium soap and less than 5% anionic surfactant. It possesses age-old cleaning and degreasing properties in the home and on outdoor terraces and paving. Black soap also has antibacterial and insecticidal value. In the garden, it can be applied to leaves to eliminate certain undesirable insects: aphids, scale insects, but also mites, red spiders, whiteflies, psyllids, and other thrips. It acts by contact, killing the larvae. It also cleans honeydew, a sticky, sugary excretion that promotes the development of sooty mould, that black mould covering leaves.

Usage advice:

- For cleaning tiled or paved surfaces: apply the product with a sponge or by spraying onto the areas to be cleaned.

- As an insecticide, use black soap in the morning, when dew is present on the vegetation, or start by lightly showering the plants, before spraying the black soap 1/2 hour later. Avoid treatment during the sunniest hours and periods of intense heat. Repeat the treatment if necessary, 7 to 10 days later and never spray on dehydrated plants.

It can be beneficial to clean branches and bark during a plant's dormant period, as soon as the leaves fall, before the spring bud burst period. This helps eliminate certain insect larvae or spores of pathogenic fungi that overwinter on the bark, awaiting the return of spring. Applying 2 to 3 preventive treatments helps limit and delay the appearance of certain pests and diseases. If you use black soap on fruit trees, shrubs or vegetable crops, wait 5 days before harvesting. If you have treated a vine, the pre-harvest interval extends to 21 days.
