第一完成单位：该项目首次完成了23个省市大豆锈病的分布、危害、损失调查及分区。对病原生物学特性、生理小种、流行学及预测预报进行了广泛深入的研究，鉴定出国内外尚未报道的2个生理小种，提出了大豆锈病夏拘于在南方寄主越冬越夏，并随气流自南向北传播的模式，建立了适用 First completed unit: The project completed the first time in 23 provinces and cities of soybean rust distribution, damage, loss investigation and zoning. The pathogenic biological characteristics, physiological races, epidemiology and forecasting were extensively studied. Two races which had not been reported at home and abroad were identified. It was proposed that soybean rust was arrested in the winter in the south, Mode of air flow from south to north, the establishment of a suitable
