Question

How viral diseases are transmitted and what are their management practices?

Answer 1

Viruses are obligate parasites; that is, they require a living host in order to grow and multiply. These virus particles infect the plants are extremely small and can be seen with the help of electron microscope. The diverse climatic condition is endowed with large number of viral disease outbreak in various cropping systems. Management of viral disease is much more difficult than that of diseases caused by other pathogens as viral disease have a complex disease cycle, efficient vector transmission and no effective viricide. But integration of various approaches is important to reduce the yield loss caused by virus diseases. There are essentially two approaches to manage virus diseases, similar to other plant diseases.

Answer 2

VIRAL DISEASES:

• Viral diseases are transmitted by means of mainly through air or droplet methods, Sneezes, Vomiting, Bites from diseased animals or insects.
• Management practices include protection from these viruses like using masks in public, using protection against mosquitoes, being clean, using tissues for cough and sneezes, washing our hands often, Use sterilized vessels, etc.
• A virus is organism that are mere nucleic acid particles that are enveloped inside a protein layer.
• The influenza virus is commonest example of this process.
• Dengue virus requires vectors like mosquitoes that spread disease.
