"Composition and method for treating bananas" The present invention relates to a composition for treating bananas against cryptogamic diseases and to a method for treating bananas by applying such a composition. Banana Sigatoka (Mycosphaerella fijiensis Morelet) is a disease found in most banana producing countries. Its economic importance is such that export banana producers are obliged to use numerous fungicide treatments each year to control it. These treatments are based on a number of fungicides of the triazole, strobilurin, EBDCs types. The object of the present invention is to propose a composition and a method for treating bananas against cryptogamic diseases, and in particular Sigatoka, which make it possible to fight effectively against these diseases, while not exhibiting phytotoxicity, or phytotoxicity. an acceptable threshold. To solve this problem, a treatment composition is provided according to the invention which comprises, as active substance, an effective amount of dodecylguanidine and / or at least one of its phytopharmaceutically compatible derivatives. Dodecylguanidine can be represented by the following formula: NH H «\ NC-NH 2 /

Cette substance est connue depuis longtemps, ainsi que ses sels d'acide organique ou inorganique. On connaît déjà l'acétate de dodecylguanidine, communément appelé "dodine", qui est un fongicide très connu et utilisé sous les climats tempérés pour le traitement des arbres fruitiers (voir par exemple US-A-2.867.562). Le brevet 2.867.562 s'applique à l'utilisation des sels de dodecylguanidine pour éradiquer des champignons qui attaquent le feuillage et les fruits des arbres fruitiers. Ce brevet mentionne que ces fongicides sont particulièrement efficaces pour contrôler la tavelure du pommier {Ventuήa inaequalis), la tavelure du poirier (Venturia pirina), la moniliose du pêcher (Monilia fructicola), la tavelure du pêcher (Cladosporium carpophilum), l'anthracnose du pêcher (Glomerella cingulata) et la cylindrosporiose du cerisier (Coccomyces hiemalis). D'autre part, le chlorhydrate de dodecylguanidine, communément appelé "DGH", est un biocide connu, utilisé pour le traitement des eaux contre les bactéries, algues, champignons et mollusques (voir par exemple GB-A-1.134.800). Le bananier par contre est une plante herbacée, monocotylée, non ligneuse, de la famille des Musaceae, qui vit dans des régions tropicales et sub-tropicales. Le bananier ne fait donc pas partie des arbres fruitiers qui sont des plantes arborescentes, ligneuses et dicotylées. La dodine a donc été uniquement testée contre des plantes d'un type éminemment différent du bananier, et cela contre des maladies de zones tempérées qui sont très éloignées du Sigatoka. Suivant la présente invention, la composition de traitement a mis en évidence une efficacité excellente et inattendue de la dodine contre le Sigatoka du bananier. Avantageusement la dodecylguanidine se présente sous la forme d'un sel d'acide monocarboxylique et/ou d'un chlorhydrate de dodecylguanidine. Pour l'application sur les feuilles du bananier, la composition, qui comprend de préférence une matière de support appropriée, se présente par exemple sous la forme d'une suspension ou émulsion aqueuse de la substance active ou d'un mélange en poudre de celle-ci avec la matière de support. De préférence, la molécule active peut être formulée sous la forme d'une suspension aqueuse, d'une poudre mouillable, d'un granulé ou encore d'un produit micro-encapsulé. L'application suivant l'invention a lieu de préférence à une dose efficace comprise entre 300 et 3000 g de substance active par hectare, et par application très avantageusement entre 680 et 1200 g de substance active par hectare. L'invention est également relative à une utilisation de la dodecylguanidine pour le traitement du bananier. Elle concerne également une utilisation de dodecylguanidine et/ou d'au moins un de ses dérivés phytopharmaceutiquement compatibles, pour la fabrication d'une composition fongicide destinée au traitement de bananiers contre des maladies cryptogamiques. Le traitement peut être curatif ou préventif. D'autres détails et particularités de l'invention sont expliqués d'une manière non limitative dans les exemples de réalisation ci-dessous. Exemple 1 Un essai d'efficacité a été réalisé en Equateur en 2002 dans la province de Los Rios. Des parcelles de 10 m sur 40 m, contenant en moyenne 60 bananiers adultes, ont été déterminées. L'essai était organisé selon le principe des blocs aléatoires et comptait 28 blocs (7 objets et 4 répétitions). Des bananiers de 5 ans de la variété Cavendish (cv. Valéry) ont été utilisés. La dodine a été appliquée sur le feuillage à raison de 800, 1000 et 1200 g de matière active (m. a.) par hectare en comparaison avec des produits de référence : propiconazole 100 g de m.a./ha, chlorothalonil 720 et 1440 g de m.a./ha et mancozeb 1333 g de m.a./ha. Les traitements ont été réalisés entre le 6 septembre 2002 et le 6 décembre 2002 (période sèche), à intervalles réguliers de 15 jours (6 traitements par objet). Les symptômes de Sigatoka ont été observés, sur une base hebdomadaire, sur les troisième et quatrième feuilles ainsi que sur les feuilles plus anciennes. L'intensité de la maladie (état d'avancement des lésions) a été évaluée et chiffrée, ainsi que le niveau d'infection (en fonction des conditions climatiques et phénologiques) et l'incidence de la maladie (niveau de dégâts). La phytotoxicité éventuelle de la dodine sur le feuillage des bananiers a également été évaluée par observation visuelle des feuilles. Les résultats d'essai sont indiqués à la figure 1 annexée, oùThis substance has been known for a long time, as well as its organic or inorganic acid salts. We already know dodecylguanidine acetate, commonly called "dodine", which is a very well-known fungicide and used in temperate climates for the treatment of fruit trees (see for example US-A-2,867,562). Patent 2,867,562 applies to the use of dodecylguanidine salts to eradicate fungi which attack the foliage and the fruits of fruit trees. This patent mentions that these fungicides are particularly effective in controlling apple scab (Ventuήa inaequalis), pear scab (Venturia pirina), peach blight (Monilia fructicola), peach scab (Cladosporium carpophilum), anthracnose peach (Glomerella cingulata) and cylindrosporiosis of the cherry tree (Coccomyces hiemalis). On the other hand, dodecylguanidine hydrochloride, commonly called "DGH", is a known biocide, used for the treatment of water against bacteria, algae, fungi and molluscs (see for example GB-A-1,134,800). The banana tree, on the other hand, is a monocotylated, non-woody herbaceous plant of the Musaceae family, which lives in tropical and sub-tropical regions. The banana tree is therefore not one of the fruit trees which are tree, woody and dicotylated plants. Dodine has therefore only been tested against plants of a type eminently different from banana, and this against diseases of temperate zones which are very far from Sigatoka. According to the present invention, the treatment composition has demonstrated an excellent and unexpected efficacy of dodine against the Sigatoka of banana. Advantageously, dodecylguanidine is in the form of a salt of monocarboxylic acid and / or of a dodecylguanidine hydrochloride. For application to banana leaves, the composition, which preferably comprises a suitable support material, is for example in the form of an aqueous suspension or emulsion of the active substance or a powder mixture of that -this with the support material. Preferably, the active molecule can be formulated in the form of an aqueous suspension, a wettable powder, a granule or even a microencapsulated product. The application according to the invention preferably takes place at an effective dose of between 300 and 3000 g of active substance per hectare, and by application very advantageously between 680 and 1200 g of active substance per hectare. The invention also relates to a use of dodecylguanidine for the treatment of banana. It also relates to a use of dodecylguanidine and / or at least one of its phytopharmaceutically compatible derivatives, for the manufacture of a fungicidal composition intended for the treatment of banana trees against cryptogamic diseases. Treatment can be curative or preventive. Other details and particularities of the invention are explained in a nonlimiting manner in the exemplary embodiments below. Example 1 An efficacy trial was carried out in Ecuador in 2002 in the province of Los Rios. Plots of 10 m by 40 m, containing on average 60 adult bananas, were determined. The trial was organized on the principle of random blocks and included 28 blocks (7 objects and 4 repetitions). 5-year-old bananas of the Cavendish variety (cv. Valéry) were used. Dodin was applied to the foliage at the rate of 800, 1000 and 1200 g of active ingredient (ai) per hectare in comparison with reference products: propiconazole 100 g ai / ha, chlorothalonil 720 and 1440 g ai / ha and mancozeb 1333 g ai / ha. The treatments were carried out between September 6, 2002 and December 6, 2002 (dry period), at regular intervals of 15 days (6 treatments per object). Symptoms of Sigatoka were observed, on a weekly basis, on the third and fourth leaves as well as on the older leaves. The intensity of the disease (progress of the lesions) was evaluated and quantified, as well as the level of infection (depending on climatic and phenological conditions) and the incidence of the disease (level of damage). The possible phytotoxicity of dodine on banana foliage was also assessed by visual observation of the leaves. The test results are shown in Figure 1 attached, where
1 = Dodine, 1200 g de m.a./ha1 = Dodine, 1200 g a.a./ha
2 = Chlorothalonil, 1440 g de m.a./ha 3 = Chlorothalonil, 720 g de m.a./ha2 = Chlorothalonil, 1440 g ai / ha 3 = Chlorothalonil, 720 g ai / ha
4 = Mancozeb, 1333 g de m.a./ha4 = Mancozeb, 1333 g a.i./ha
5 = Dodine, 1000 g de m.a./ha5 = Dodine, 1000 g ai / ha
6 = Dodine, 800 g de m.a./ha6 = Dodine, 800 g a.a./ha
7 = Propiconazole, 100 g de m.a./ha Les résultats indiquent que la dodine contrôle le Sigatoka de façon identique aux produits de référence aux doses de 800 et 1000 g de m.a./ha et montre une efficacité significativement supérieure (Duncan 0,05 %) aux substances de référence à 1200 g de m.a./ha. Aucune phytotoxicité inacceptable n'a été mise en évidence. Exemple 2 Un essai d'efficacité a été réalisé en Equateur en 2003 dans la province de Los Rios. Des parcelles de 15 m sur 25 m, contenant en moyenne 52 bananiers adultes, ont été déterminées. L'essai était organisé selon le principe des blocs aléatoires et comptait 32 blocs (8 objets et 4 répétitions). Des bananiers de 6 ans de la variété Cavendish (cv. Valéry) ont été utilisés. La dodine a été appliquée sur le feuillage à raison de 800, 1000 et 1200 g de matière active (m. a.) par hectare en comparaison avec des produits de référence : propiconazole 100 g de m.a./ha, funbeconazole 100 g de m.a./ha et trifloxystrobine 75 g de m.a./ha. Les traitements ont été réalisés entre le 21 janvier 2003 et le 2 mai 2003 (période pluvieuse), à intervalles réguliers de 13 jours (8 traitements par objet) à raison de 30 I de bouillie par hectare (émulsion aqueuse dans 6 I d'huile par hectare). Les symptômes de Sigatoka ont été observés, sur une base hebdomadaire, sur les troisième et quatrième feuilles ainsi que sur les feuilles plus anciennes. L'intensité de la maladie (état d'avancement des lésions) a été évaluée et chiffrée, ainsi que le niveau d'infection (en fonction des conditions climatiques et phénologiques) et l'incidence de la maladie (niveau de dégâts). La phytotoxicité éventuelle de la dodine sur le feuillage des bananiers a également été évaluée par observation visuelle des feuilles. Les résultats de cet essai sont indiqués à la figure 2 annexée, où A = Propiconazole, 100 g de m.a./ha B = Fenbuconazole, 100 g de m.a./ha C = Trifloxystrobine, 75 g de m.a./ha D = Dodine, 800 g de m.a./ha E = Dodine, 1000 g de m.a./ha F = Dodine, 1200 g de m.a./ha Les résultats indiquent que la dodine contrôle le Sigatoka de façon identique aux produits de référence aux doses de 800, 1000 et 1200 g m.a./ha (Duncan 0,05 %). Aucune phytotoxicité inacceptable n'a été mise en évidence. 7 = Propiconazole, 100 g ai / ha The results indicate that dodine controls Sigatoka identically to the reference products at the doses of 800 and 1000 g ai / ha and shows a significantly higher efficacy (Duncan 0.05%) to reference substances at 1200 g ai / ha. No unacceptable phytotoxicity has been demonstrated. Example 2 An efficacy trial was carried out in Ecuador in 2003 in the province of Los Rios. Plots of 15 m by 25 m, containing an average of 52 adult bananas, were determined. The test was organized on the principle of random blocks and included 32 blocks (8 objects and 4 repetitions). 6 year old bananas of the Cavendish variety (cv. Valéry) were used. Dodin was applied to the foliage at the rate of 800, 1000 and 1200 g of active ingredient (ai) per hectare in comparison with reference products: propiconazole 100 g ai / ha, funbeconazole 100 g ai / ha and trifloxystrobin 75 g ai / ha. The treatments were carried out between January 21, 2003 and May 2, 2003 (rainy period), at regular intervals of 13 days (8 treatments per object) at the rate of 30 I of spray solution per hectare (aqueous emulsion in 6 I of oil per hectare). Symptoms of Sigatoka were observed, on a weekly basis, on the third and fourth leaves as well as on the older leaves. The intensity of the disease (progress of the lesions) was evaluated and quantified, as well as the level of infection (depending on climatic and phenological conditions) and the incidence of the disease (level of damage). The possible phytotoxicity of dodine on banana foliage was also assessed by visual observation of the leaves. The results of this test are shown in attached Figure 2, where A = Propiconazole, 100 g ai / ha B = Fenbuconazole, 100 g ai / ha C = Trifloxystrobin, 75 g ai / ha D = Dodine, 800 g ai / ha E = Dodine, 1000 g ai / ha F = Dodine, 1200 g ai / ha The results indicate that dodin controls Sigatoka identically to the reference products at the doses of 800, 1000 and 1200 g ai / ha (Duncan 0.05%). No unacceptable phytotoxicity has been demonstrated.
