Halo blight

[2] Halo blight is affected by environment factors and enter through plant injuries or natural openings.

These spot progressively turn dark brown and are surrounded by a wide greenish yellow halo.

[4] Similar to foliage symptoms, halo blights causes water-soaked spots on vegetative pods.

[7] Halo blight can be dispersed by contact between wet leaves, rainfall, irrigation or people and animals moving through infested fields.

As a result, disease symptoms appear within 2 days, where chlorotic lesions appear as yellow halos surrounding black necrotic spots on the infected plants.

The pathogen enters the plant through wounds or stomata and hydathodes during periods of high relative humidity or free moisture.

[15] Seeds that are sanitized from the previous year to show no bacterial signs can be planted without the worry of spreading the pathogen.

The Bordeaux mixture and streptomycin are two of the main foliar sprays that have shown results when treating Halo blight.

[citation needed] Halo Blight is an important disease to beans, a money crop, which allow the pathogen Pseudomonas syringae to continue its lifespan.

Fields that are affected by this bacteria are at risk for the spread of it by way of rain, wind, or organisms but a widespread infection isn’t common with the cultural practices that are now used.
