The Finalsan Natural Herbicide 500 ml. Concentrate is a fast-acting solution formulated with pelargonic acid to eliminate weeds and mosses through direct contact. Concentrated format, easy to dilute and suitable for different outdoor areas.

Finalsan concentrated herbicide from Neudorff is designed to control unwanted vegetation through a contact action on the green parts of the treated plants.
The formulation contains 186.7 g/L of pelargonic acid, a fatty acid that is also naturally found in different plants.
The 500 ml concentrated format allows you to prepare up to 3 liters of spray solution, offering a practical alternative for gardens, paths, areas around ornamental plants, and spaces where unwanted weeds appear.
The first effects may begin to be noticeable from about one hour, depending on environmental conditions.
As it is a total and non-selective herbicide, spraying should be directed exclusively at the vegetation to be eliminated, avoiding leaves and green parts of ornamental plants or crops that should be preserved.
The Natural Herbicide Finalsan 500 ml is a concentrated preparation from the Neudorff brand intended for the control of weeds and mosses. The main active ingredient is pelargonic acid at a concentration of 186.7 g/L. It acts directly on the green tissues reached during spraying, altering cell structures and causing rapid desiccation of the treated vegetation.
Unlike a systemic herbicide, this natural contact herbicide works mainly on the surfaces reached by the mixture. For this reason, it is important to wet the unwanted vegetation evenly and avoid indiscriminate application.
The manufacturer defines Finalsan as a product with total and non-selective action. This means it can affect any green plant tissue it falls on directly. Woody parts behave differently, but leaves, young shoots, and vegetation to be preserved must be protected during application.
The Natural Herbicide Finalsan 500 ml. Concentrate is mainly used to eliminate weeds and mosses present in different outdoor spaces. It can be especially practical for controlling spontaneous vegetation on paths, edges, ornamental areas, areas near trees or shrubs, and other places where weeds are difficult to remove manually.
Thanks to the contact mechanism, effects can start to be visible quickly. Under suitable conditions, the manufacturer indicates appreciable results from about one hour. The speed will depend on factors such as temperature, vegetation condition, and weather conditions.
In an indoor growing environment, it is advisable to clearly differentiate between weeds and pests. Finalsan can be part of maintenance tasks for outdoor or auxiliary areas where unwanted vegetation appears, but it is not a product intended to combat indoor crop pests such as red spider mite, thrips, aphids, whitefly, or other insects and mites. To combat pests in indoor cultivation, products specifically indicated for each target organism should be used.
Before preparing the natural concentrated herbicide, it is advisable to shake the container and always consult the current product label. The 500 ml format allows you to obtain approximately 3 liters of prepared spray mixture. As a usual reference for this concentrate, you can mix about 165-166 ml per liter of water.
Once the mixture is prepared, it should be sprayed directly onto the green parts of the weeds or moss, ensuring even coverage. For good results, the vegetation should be dry at the time of treatment.
Avoid spraying when it has just rained or after watering the area. It is also advisable to check the weather forecast and avoid applications when there is an immediate possibility of rain. Splashes on plants to be preserved should be avoided, as this natural contact herbicide does not distinguish between a weed and an ornamental plant when it reaches green tissues.
Once the treated area is completely dry, the manufacturer indicates that people and pets can return to the area. As with any plant protection product, the instructions, handling precautions, and protection recommendations indicated on the packaging must be followed.
