Pseudomonas fuscovaginae

Pseudomonas fuscovaginae is a Gram-negative, rod-shaped bacteria that belongs to the Pseudomonas genus. It is a plant pathogen that causes diseases in several crops, most notably in rice, where it causes a disease known as bacterial sheath brown rot.

Characteristics

Pseudomonas fuscovaginae is a motile bacterium due to the presence of a single flagellum. It is capable of aerobic respiration, and it does not form spores. The bacterium is oxidase positive and catalase positive, which are common characteristics of the Pseudomonas genus.

Pathogenicity

Pseudomonas fuscovaginae is a pathogen of several plant species, but it is most well-known for causing bacterial sheath brown rot in rice. The disease is characterized by the formation of brown lesions on the sheath of the rice plant, which can lead to significant yield losses. The bacterium can also cause diseases in other crops, such as maize, wheat, and barley.

Control

Control of Pseudomonas fuscovaginae is challenging due to its ability to survive in a wide range of environmental conditions. However, several strategies can be used to manage the disease, including the use of resistant cultivars, crop rotation, and biocontrol agents. Chemical control with bactericides can also be effective, but it is not always a sustainable solution due to the potential for the development of antibiotic resistance.
