Bacterial blight is an important bacterial disease of soybean. This disease is seed transmitted and is most prevalent during cool, wet growing conditions.

Pods develop water lesions that later change color to brown. Seed are infected and become discolored, shriveled, and may develop lesions.

This test is typically completed in four to five days and results are reported as positive or negative.
