This article is a list of diseases of rice (Oryza sativa). Diseases have historically been one of the major causes of rice shortages. [1]: 434 ...
The highest mortality rates occur in L. vannamei, which is one of the two most frequently farmed species of shrimp. Untreated, the disease causes mortality rates of up to 90 percent within 30 days. A first outbreak of NHP had been reported in Texas in 1985; the disease then spread to shrimp aquacultures in South America. [2]
The shrimp-farming industry has developed several broodstocks of both P. stylirostris and P. vannamei that are resistant against IHHN infection. [1] The disease is caused by a single-stranded DNA virus of the species Decapod pestylhamaparvovirus 1, earlier known as IHHN virus, the smallest of the known penaeid shrimp viruses (22 nm). [2]
The increased occurrence of devastating viral diseases in shrimp culture systems threatens the sustainability of both the aquaculture industry and the commercial shrimp fishery. HPV is associated with reduced growth rates of juvenile shrimp without showing any gross signs of disease and can lead to mass mortalities in shrimp populations. [21]
White spot syndrome (WSS) is a viral infection of penaeid shrimp.The disease is highly lethal and contagious, killing shrimp quickly. Outbreaks of this disease have wiped out the entire populations of many shrimp farms within a few days, in places throughout the world.

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.
