云南农业大学植物病理重点实验室朱有勇教授领导的研究组,对利用生物多样性控制稻瘟病进行攻关研究,日前获得重大突破。不仅经全国大面积试验推广在防病、增产增收和大幅度减少农药施用等方面取得显著效果,而且在世界上首次提出了利用水稻遗传多样性持续控制稻瘟病的理论和技术,标志着我国在这一领域的研究已跃居国际领先水平。稻瘟病是世界性的水稻主要病害,长期以来主要采取选育推广抗病良种、施用化学农药、化学肥料和保健栽培管理调控等措施进行常规防治,不仅增加水稻生产成本,而且污染和破坏农田生态环境。为探索控制稻瘟病危害的新途径,朱有勇 Recently, a research team led by Professor Zhu You-yung, a key plant pathology laboratory at Yunnan Agricultural University, has made major breakthroughs in the research on controlling rice blast by using biodiversity. Not only has the national large-scale trial popularization have achieved remarkable results in prevention and treatment of diseases, increase of production and income, and drastic reduction of the application of pesticides, etc., but also put forward the theory and technology of using rice genetic diversity to control rice blast continuously for the first time in the world. Research in this area has leapt to the leading international level. Rice blast is the world’s major rice disease. For a long time, it has been mainly used for breeding and popularizing disease-resistant varieties, chemical pesticides, chemical fertilizers and health-related cultivation and management measures to prevent and control conventional rice crops. It not only increases rice production costs but also pollutes and damages farmland ecology surroundings. In order to explore a new way to control the harm of rice blast, Zhu Youyong
