The soybean cyst nematode, Heterodera glycines, was introduced into Ohio in the spring of 1980. No known soybean field infestations, however, have been found at this time. Cysts of this nematode were transported into the state in soil adhering to tomato transplants. Two fields are known to have been planted to these tomato transplants and are assumed to have cysts disseminated throughout. Additional fields that received transplants from the same location are being sought.
