[1] It results in both the Cercospora leaf blight and purple seed stain diseases on soybean and is found almost worldwide.

Seed: The disease on the host soybean itself can be determined by a light activated red perlene quinon, cercosporin, with a molecular weight of 534.

If this defoliation occurs during the period of seed fill, significant yield losses have been recorded (Schneider et al. 2009).

C. kuckuchii has a large range of habitable environments, but it is most prolific, and the greatest threat in top soybean producing countries such as Brazil, China, the United States, and India (Soares et al. 2015).

Seed treatment foliar fungicides applied during R3- R5 can reduce blight incidence and severity.

The farmers can blend infected beans with clean and still sell them (Successful Farming Staff 2018).
