Recently, the Grain and Oil Risk Factor Assessment and Safety System Laboratory of the Institute of Quality and Safety of Jiangsu Academy of Agricultural Sciences has been continuously in Plant Disease, Plant Pathology, World Mycotoxin Journal, etc. The international mainstream academic journals in this field published online the latest research results of the risk assessment of rice mycotoxin pollution in our province. Relevant research results fill the gap in the over-summer life history of toxin-producing Fusarium in rice-wheat rotation areas in my country, and provide a key theoretical basis for the realization of toxin closed-loop full-process management and control. The above-mentioned research results have been awarded by the National Key Research and Development Program, the National Natural Science Foundation of China, and Jiangsu Agriculture Funds for independent innovation of science and technology and projects for the introduction of talents from overseas experts of the Academy are funded.
Jiangsu Province is a typical rice-wheat rotation area in my country, and it is also an area where wheat scab frequently occurs and fusarium toxin is heavily polluted. In recent years, affected by global climate change and changes in farming systems, the risk of disease and toxin contamination of rice along the Yangtze River and along the Huaihe River in our province has increased due to pathogenic fungi such as toxin-producing Fusarium, seriously threatening the quality of rice and the safety of rice food. The Grain and Oil Research Office focused on the problem of mycotoxins in grains, and continued to track and monitor the current status of mycotoxins in newly harvested rice in the main rice-producing areas of our province. It was found that more than 70%of the rice in the region was affected by fusarium toxin, orytoxin and alternaria toxin Among them, the highest values of vomitin, nivalenol, F-2 toxin, fumonisin B1 and orytoxin reached 19100 μg/kg, 12200 μg/kg, 1300 μg/kg, 2200 μg/kg and 1087 μg/kg, provide important data support for grasping the change law of mycotoxins pollution in rice in China and formulating limit standards. The research team also systematically studied the population characteristics of toxin-producing fungi in the area, and clarified the population characteristics of toxin-producing fungi in rice in our province and the law of infecting and producing toxins, and found that gramineous weeds near rice fields can be used as an alternative host for toxin-producing Fusarium to promote disease Develop and exacerbate toxin pollution.
