Certain strains of Rhizopus microsporus use agricultural rice as a host, causing the disease Rice Seedling Blight. This infection is first observed by the fast swelling of seedling roots, but displays no further signs of infection. The main causal agent of Rice Seedling Blight is attributed to the endosymbiotic relationship with Paraburkholderia sp
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.
This article is a list of diseases of cultivated wild rice (Zizania palustris). Fungal Brown Spot is the only significant commercial disease of cultivated wild rice. It is found mostly in the cultivated wild rice fields of Minnesota.
Cochliobolus miyabeanus is an important plant pathogen because it causes a common and widespread rice disease that causes high level of crop yield losses. It was a major cause of the Bengal famine of 1943, where the crop yield was dropped by 40% to 90% and the death of 2 million people was recorded. [3]
Rice-sheath blight is a disease caused by Rhizoctonia solani (teleomorph is Thanetophorus cucumeris), a basidiomycete, that causes major limitations on rice production in India and other countries of Asia. [1] It is also a problem in the southern US, where rice is also produced. [2] It can decrease yield up to 50%, and reduce its quality. [3]
Xanthomonas oryzae epidemics can cause yield losses ranging from 2-74%, [2] and the bacteria can be carried on rice seeds, causing further disease spread. [3] The host resistance gene, Xa21, from Oryza longistaminata, is integrated into the genome of Oryza sativa for its broad-range resistance to rice leaf blight caused by X. o. pv. oryzae. [4]
Foodborne illness (also known as foodborne disease and food poisoning) [1] is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, [2] as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes.
