Research Progress in Brown Spot Disease of Zizania latitfolia

Abstract: The research results on the occurrence of brown spot disease of Zizania latifolia , identification of pathogen and its biological characteristics, occurrence regularity and disease control in recent years were reviewed. The research progress in the selection of disease resistant cultivars, agricultural control, chemical control and plant immune inducer control of brown spot disease of Zizania latifolia was summarized. The problems in the research of brown spot disease of Zizania latifolia were summarized. In the future, it was necessary to strengthen the research on the diversity and pathogenicity differentiation of the pathogen species group and the infection mechanism and pathogenic mechanism of the pathogen, further collect, screen and identify the disease resistant germplasm resources of Zizania latifolia , cultivate excellent resistant cultivars, carry out the monitoring of drug resistance and resistance mechanism of brown spot diseases of Zizania latifolia , and screen new ecological friends good chemical pesticides and low toxicity, high effi ciency biocontrol agents.
