大豆孢囊线虫病是大豆的一种重要病害。1952年日本一户稔发现其病原线虫定名为大豆孢囊线虫(Heterodera glycines Ichinohe),由此虫所致的大豆病害称大豆孢囊线虫病。此后,美、日等国陆续报道本国发生危害情况,1970年,美国报道已有11个州发生大豆孢囊线虫病。近年来美国和日本已鉴定出4—5个生理小种,且培育出一部分抗病品种。我国东北地区发病较早且严重,河南、河北、山东、山西等省也相继发现,成为生产上的突出问题。我省1981年在阜阳开始发现大豆孢囊线虫病,1982—1985年
Soybean cyst nematode disease is an important disease of soybean. In 1952, a Japanese shrew found its pathogenic nematode named as Heterodera glycines Ichinohe, and the soybean disease caused by the worm was called soybean cyst nematode. Since then, the United States, Japan and other countries one after another reported the occurrence of hazardous conditions in their own country, in 1970, the United States reported that 11 states have soybean cyst nematode disease. In recent years, the United States and Japan have identified 4-5 physiological races, and bred a part of resistant varieties. The morbidity in northeastern China was earlier and more serious, and successive provinces such as Henan, Hebei, Shandong and Shanxi also discovered one after another and became prominent problems in production. In 1981, the province began to discover soybean cyst nematode disease in Fuyang, 1982-1985
