Finalsan

186.7 g/l pelargonic acid

The active agent of Finalsan^® is pelargonic acid. Pelargonie acid - also known as nonoic acid - belongs to the fatty acids. In nature it is found, for instance, in natural oils and in gerani­ums (Geraniaceae).

Finalsan^® is a non-selective contact herbicide. The active agent of Finalsan^® - pelargonic acid - penetrates the wax layer (cuticle) of the leaves. The lipophile part of the fatty acid then destroys the cell membranes of the plant's epidermic cells - the outer skin - there­ by inducing the rapid release of the substances contained in the cells so that the plant quickly dries up.

Finalsan^® is effective against all mono- and di-cotyledonous weeds such as dandelions, plantains, grasses, bindweeds, nettles and thistles. The leaves of the goutweed and the common field horse-tail are also rapidly killed by Finalsan^® which can also be used to control moss and algea since many kinds of moss and algea can be effectively exterminated with Finalsan^®.

The leaves of plants treated with Finalsan^® turn brown within a few hours - an effect that is associated with both mono- and di-cotyle­donous weeds.

Thorough wetting of the weeds

Finalsan^® is applied by spraying. Intensive weed spraying must be assured since only the directly wetted plant parts die. An optimal effect is assured when the weeds are 5 to 10 cm tall. The weeds should be dry when they are sprayed because, otherwise, the active agent will be diluted.

Temperatures during application

Finalsan^® is effective within a wide tempera­ture range. Since its effect is independent of the plant's metabolic processes Finalsan^® can be applied in spring right up to late autumn. The minimum temperature during application is 10 °C. Apply preferably at temperatures below 25 °C.

Repeat treatment

With root-stock weeds it is advisable to repeat treatment after 4 to 6 weeks.

*Application of the agent on open areas that are not used for agricultural, forestry or horticultural purposes is only permissible with the approval of the responsible local authority (section 6.2 &6.3 of the Plant Protection Act).

Finalsan^® has proved its worth for rapid and lasting control of mosses and algae on open stacking/storage yards. The pelargonic acid active agent ensures rapid and sustained destruction of the tissue of algae and mosses. Consequently it takes months for mosses and algae to recolonise such areas. Moreover, the danger of slipping on open stacking/storage yards is greatly diminished.

Furthermore, this prevents the multiplication of sciarid and marsh flies which like to lay their eggs underneath algae covers. The active agent is rapidly decomposed on the free areas so that pots and containers can once again be deposited on the areas soon after treatment.

Studies conducted by the Agricultural Chamber of Lower Saxony indicate that the application of Finalsan^® against mosses and algae on open stacking/storage yards with a filleted surface results in a distinct reduction of infestation by fungal pests. lt was established that the infection potential within tree and ornamental plant nurseries by important diseases such as Rhizoctonia solani, Phytophthora cinnamomi and Cylindro-cladium buxicola, can be significantly diminished.

Finalsan^® is a total herbicide that kills all con­tacted green plant parts. Consequently, do not allow the agent to come into contact with the leaves of crop plants. Woody plant parts are not damaged so that Finalsan^® can be applied under trees and shrubs without causing any problems. The agent is not translocated via green or brown bark parts of trees or shrubs.

Finalsan^® is well tolerated by materials. In some cases white patches may appear when it is applied on dark materials, but these quickly disappear after rainfall. Avoid contact with synthetic resin plates and surfaces containing copper or zinc. Contact with these materials can result in a more persistent discolouration. With other sensitive materials check compat­ibility at a concealed point.

Finalsan^® is miscible with herbicides contain­ing glyphosate. The effectiveness of the two agents complement each other.

Waters: No conditions regarding distance to waters. Possible national legal stipulations must be observed. Application in the immedi­ate vicinity of inshore and coastal waters is impermissible. Harmful to aquatic organisms. Finalsan^® in waters is broken down within a few days. 50 % of the agent is broken down already after 1 day.

Soil: Finalsan^® is rapidly broken down in the soil. 50 % of the active agent is broken down already after 3 days.

Beneficial organisms: Not harmful to benefi­cial organisms.

Bees: Not harmful to bees (B4).
