Viruses have long been suspected as triggers for immune-mediated diseases such as multiple sclerosis but showing a direct role for viral causation is difficult in those diseases, and mechanisms, whereby viral infections could lead to autism, are speculative.
Although plant viruses are not as well understood as their animal counterparts, one plant virus has become very recognizable: tobacco mosaic virus (TMV), the first virus to be discovered. This and other viruses cause an estimated US$60 billion loss in crop yields worldwide each year. Plant viruses are grouped into 73 genera and 49 families ...

This category includes economically significant plant diseases and the organisms that cause them including, fungi, bacteria, protists and viruses. For more information on plant pathology see phytopathology. For insects that transmit plant pathogens see Insect vectors of plant pathogens.
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). [1] Organisms that cause infectious disease include fungi , oomycetes , bacteria , viruses , viroids , virus -like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . [ 2 ]

The two viruses were differentiated in 1965 and 1967 using particle lengths, serology, host range, [9] inclusions, and aphid transmissibility. [10] PapMV causes mild mosaic symptoms on papaya leaves and stunting of the plant. [11] It is known to occur in South America (Bolivia, Peru, and Venezuela) and the USA.
The disease is spread through sap containing the virus and can be transferred to other areas mostly by mechanical means such as lawn mowers and other equipment. [7] To minimize spread of sugarcane mosaic virus all equipment used should be sanitized. Fungicides and other pesticides have been shown to be ineffective when dealing with viral disease.
