    Bacterial Bean Blights. There are three bacterial diseases of bean which are very similar, Common Bligh t (Xanthomonas campestris pv. phaseoli), Halo Blight (Pseudomonas syringae pv. phaseolicola), and Fuscous Blight (a variant of X. campestris li).In general, they affect only beans and closely related plants. The most common bean diseases are: Anthracnose, bacterial blights, common bean mosaic, and rust. Common Bean Diseases. Anthracnose is caused by a fungus, which is carried in seeds and lives in the soil on the remains of diseased plants. Rotating crops is important for control.

    Common and fuscous blight pathogens are very similar in both culture media and symptom development and often occur in fields simultaneously. Common bacterial blight is a warm-weather disease, and the greatest damage to bean plants occurs when air temperatures are 82°F to 90°F (28° to 32°C).   Common bacterial blight, caused by Xanthomonas campestris pv. phaseoli or Xanthomonas axonopodis pv. Phaseoli and, and halo blight, caused by Pseudomonas syringae pv. Phaseolicola, are normally the most common pathogens. These diseases can overwinter in plant debris from a previous dry bean crop and in bean seed from infected plants.

    Common bacterial blight of dry beans has been seen in Nebraska since the crop was first introduced in the s. As the name implies, it’s considered to be a major problem wherever beans are grown, and is the most commonly observed bacterial disease in the Central High Plains. It can be highlyFile Size: 1MB. The pathogen can be found on the leaves of many plants, but only causes disease on bean. Rain, irrigation water, tools, equipment, and humans can spread the pathogen. Infection occurs when bacterial cells are deposited onto leaves by splashing water, aerosols, or from contaminated seed, and then multiply to form large populations.
