EPPO Distribution List for Heterodera glycines
The EPPO Secretariat has worked from the literature on the occurrence of Heterodera glycines in USA and can now give more details on its distribution. In addition, Chile has denied the presence of H. glycines (see EPPO RS 96/158) Therefore, its distribution list can be modified as follows.
EPPO Distribution List: Heterodera glycines
The first report of H. glycines was from Japan in 1916. Earlier observations date back to 1881. In 1938 the nematode was reported from Manchuria (then an independent state, now in China) and then from several other parts of Asia, including the Amur District in Russia. It was first detected in the USA in 1954 and subsequently found in many states with the extension and intensification of soyabean cultivation. It is still a matter of debate whether H. glycines is indigenous to North America.
