coatings. Environment Hemp mosaic virus is known as one of the most stable viruses. It has a very wide survival range. As long as the surrounding temperature remains below approximately 40 degrees Celsius, hemp mosaic virus can sustain its stable form. All it needs is a host to infect. Greenhouses and botanical gardens would provide the most favorable condition for the virus to spread, due to the high population density of possible hosts and the constant temperature throughout the year. The virus "occurs naturally in leguminous plants in Australia, India, Nigeria, and the United States" and has been described with a variety of names based on the host from which it was isolated. It has been observed to infect more than 40 host species across seven different families of plant.
