Application of 1-aryl-4-pyridone compound

The invention discloses application of a 1-aryl-4-pyridone compound, and provides application of a compound of a structure of a formula (I) shown in the description in inhibiting activity of plant pathogenic bacteria. The compound of the structure of the formula (I) shown in the description has outstanding broad-spectrum antifungal activity upon plant pathogenic bacteria in agricultural production, and meanwhile, has a prevention and treatment effect on bacterial disease of crops. In-vivo biological assay shows that the compound of the structure of the formula (I) shown in the description hasa prevention and control effect greater than 95% on cucumber downy mildew, cucumber target leaf spot, wheat scab and tomato gray mold. Meanwhile, results of postharvest fresh-keeping tests of mangos show that the compound is capable of effectively controlling postharvest diseases of mangos and in addition, prolonging the fresh-keeping time of the mangos. In addition, results show that the compoundis also capable of effectively controlling bacterial leaf blight of rice in pot experiments, and is more effective than a commercial fungicide zhongshengmycin. In conclusion, the 1-aryl-4-pyridone derivative of the formula (I) shown in the description has broad-spectrum plant pathogenic fungus resistance and bacterial activity, and is a type of lead compounds with wide bioactivity.
