Abstract

La présente invention concerne le TRAXNOX, qui est le fongicide résultant du mélange suivant: méthyl (2 E) -2 -(2 - {[6 - (2-cyanophénoxy) pyrimidin-4-yl] oxy} phényl)-3-méthoxyacrylate + 2 RS1 3 RS, 2 RS, 3 SR ) -2 - (4-chlorophényl)-3- cyclopropyl-1-(1 H -1,2,4-triazol-1-il) butan-2-ol. Il appartient aux groupes chimiques des produits systémiques, les strobilurines et les triazols, en dosage de 0,4 L/ha et en volume de 300 L/ha. Sa principale caractéristique est d'éliminer le champignon phytopathogène. Il satisfait précisément à la norme de fiabilité étant donné qu'il résiste à la dégradation rapide et, lorsqu'il se décompose, ses sous-produits sont toxiques pour le pathogène, mais n'affectent pas la plante hôte. Il est essentiel dans le traitement de la maladie sur des cultures étendues. Le fongicide TRAXNOX présente une action fongicide en 72 heures. Il est efficace dans la prévention étant donné qu'il inhibe le développement du syndrome de la maladie dans la plante lors d'une application subséquente à une invasion par le pathogène, avec absence de pustules, qui sont les structure du champignon pathogène. Il exerce une action curative confinée aux phases de post-infection et pré-symptomatiques, séchant et éradiquant les pustules, qui sont alors dénuées de spores. Il présente en outre une action d'éradication, avec des effets au stade post-symptomatique, exterminant le champignon Puccinia psidii présent chez Eucalyptus sp.
