The composition according to the invention comprises a very major proportion of inert charcoal and a minor proportion of active charcoal and is in pulverulent form, consisting of particles with a diameter of less than 200 µm, in the form of a powder or of granules. The inert charcoal used has a specific surface area of between 100 m2/g and 200 m2/g and comprises 60% to 80% of particles having macropores, 5% to 10% of particles having mesopores and 5% to 15% of particles having micropores. The active charcoal used has, for its part, a specific surface area of between 800 m2/g and 1200 m2/g and essentially has micropores. According to the embodiment, the composition can also comprise a proportion of Montmorillonite green clay and/or a minor proportion of ionized water. The composition according to the invention makes it possible to treat plants infested with fungi, without using pesticides. |
