| Occurrence of the White Soybean Cyst Nematode, Heterodera sojae, and the Soybean Cyst Nematode, H. glycines, in Korea |
|
Soybean cyst nematode (Heterodera glycines, SCN) is the most harmful pathogen of soybean (Glycine max (L.) Merr.) worldwide. In 2016, a new soybean-parasitic cyst nematode, Heterodera sojae (the white soybean cyst nematode) was found parasitizing the roots of soybean plants in Korea. To investigate the distribution and population density of H. sojae, 943 soil samples were collected from soybean fields in all nine provinces in Korea in 2017 to 2018 |

AbstractSoybean cyst nematode (Heterodera glycines, SCN) is the most harmful pathogen of soybean (Glycine max (L.) Merr.) worldwide. In 2016, a new soybean-parasitic cyst nematode, Heterodera sojae (the white soybean cyst nematode) was found parasitizing the roots of soybean plants in Korea. To investigate the distribution and population density of H. sojae, 943 soil samples were collected from soybean fields in all nine provinces in Korea in 2017 to 2018. Cyst nematodes were detected in 343 samples (36.4%) from eight of the nine provinces, except the island of Jeju province. Among the 343 samples, H. glycines was found in 227 samples (66.2%), H. sojae in 95 samples (27.7%), and 21 samples (6.1%) were infested with both H. sojae and H. glycines. Wide distribution of H. sojae in soybean fields indicates that H. sojae is an important cyst nematode species parasitizing soybean together with H. glycines. |
