Inability of a Seed Treatment with Pseudomonas cepacia to Control Heterodera glycines on Soybean

A commercial seed treatment containing Pseudomonas cepacia was applied to Glycine max cv. Williams 82 (susceptible to Heterodera glycines) and was compared to Fayette soybean (resistant to H. glycines) for control of H. glycines at two locations in Illinois. The soil at the first location was sandy in texture and the field was irrigated, whereas the soil at the second location was a silty clay loam and the field was not irrigated. At both locations there was no yield increase associated with the seed treatment , but yield of Fayette was significantly (P < 0.05) greater than Williams 82 regardless of treatment.
