Beet necrotic yellow vein virus (BNYVV) is a plant virus, transmitted by the plasmodiophorid [1] Polymyxa betae. The BNYVV is a member of the genus Benyvirus [2] and is responsible for rhizomania, a disease of sugar beet (Rhizo: root; Mania: madness) that causes proliferation of thin rootlets, and leads to a smaller tap root with reduced sugar content.

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 ]
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 ...
Plant disease triangle. Epidemiology is the study of factors affecting the outbreak and spread of infectious diseases. [10] A disease triangle describes the basic factors required for plant diseases. These are the host plant, the pathogen, and the environment. Any one of these can be modified to control a disease. [11]

Since the 1970s, Willett and a team at Harvard have been studying types of dietary fat, tracking over 200,000 people for more than four decades to monitor the impact of nutrition on the incidence ...
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.
