Description

FUNGICIDE COMPOSITIONS FOR RICE-PLANTS RICE AND METHODS FOR CONTROL OF DISEASES OF RICE-PLANT RICE BACKGROUND OF THE INVENTION The present invention relates to a fungicidal composition for rice-rice plants, which exerts a synergistic effect, which can not be derived from a single fungicide spectrum or an extended one, to control the damage by disease, by means of the mixture of two or more different agents. To control the damage by diseases of paddy-rice plants, fungicide agents such as probenazole (common name) and triciclazole (common name) have been developed and used against the Blight (Pyricularia oryzae), cichlomezine (common name) and validamycin (name) common) and similar against the blast of the pod (Rhizoctonia solani), and ferimzone (common name), fthalide (common name), iprodione (common name) and the like against the leaf spot of Helminthosporium (Cochliobolus miyabeanus). At present, the aging of agricultural workers has advanced further and the reduction of labor in any job has been desired REF .: 30755 agricultural. Also in the work of application of the agents for the purpose of controlling the damage by diseases of paddy-rice plants, to lighten the work, it has been intensely desired to develop an agent having a broad fungicidal spectrum or a fungicidal composition that is useful for controlling various diseases without losing the characteristics of each compound of the active ingredient. However, the time to control each disease is not always the same, and the combined use alone can not exert the desired effect to adequately control the damage of the disease.
