Location: Brown stem rot is more prevalent in fields with a long history of soybean cultivation. Especially those in continuous soybean production, have a greater probability of having economic losses to brown stem rot.

Time of infection: The brown stem rot fungus resides in the soil and generally attacks plants during the first half of the growing season. No obvious symptoms develop on plants until after flowering then symptoms develop rapidly during periods of dry weather.

Management:
· Crop rotation
· Resistant varieties
