The bacteria can affect the cotton plant during all growth stages, infecting stems, leaves, bracts and bolls. It causes seedling blight, leaf spot, blackarm (on stem and petioles), black vein and boll rot.
It is now thought that the cotton dust directly causes the disease and some believe that the causative agents are endotoxins that come from the cell walls of gram-negative bacteria that grow on the cotton. [4] Although bacterial endotoxin is a likely cause, the absence of similar symptoms in workers in other industries exposed to endotoxins ...

Bacterial seedling blight of rice (Oryza sativa), caused by pathogen Burkholderia plantarii [4] Early blight of potato and tomato, caused by species of the ubiquitous fungal genus Alternaria Leaf blight of the grasses e.g. Ascochyta species [ 5 ] and Alternaria triticina that causes blight in wheat [ 6 ]
Compared to 23 common soybean diseases, sclerotinia stem rot was the second most problematic disease in the United States from 1996 to 2009. [ 8 ] [ 9 ] For soybeans, crop yields are inversely correlated with the incidence of Sclerotinia stem rot; an estimated of 0.25 metric ton per ha is lost for each 10% increment of diseased plants.
The fungus also causes many diseases like damping off, seedling blight, collar rot, stem rot, charcoal rot, basal stem rot, and root rot. [2] Although brown lesions may form on the hypocotyls or emerging seedlings, many symptoms occur during or after flowering, including grey discoloration of the stem and taproots, shredding of plant tissue in ...
Management of bacterial leaf blight is most commonly done by planting disease resistant rice plants. PSB Rc82 is the standard variety of rice used in Southeast Asia, and the use of this cultivar enables the harvest of an estimated 0.8 million metric tons of rice per cropping season that would have otherwise been lost to bacterial leaf blight.
Cotton fever rarely requires medical treatment but is sometimes warranted if the high fever does not break within a few hours of the onset. It will usually resolve itself within a day. Soaking in a warm bath along with a fever reducer can alleviate symptoms. Extreme cases (particularly severe or long-lasting) can be treated with antibiotics.
