How quickly does mosaic virus spread?
Cucumber mosaic virus is spread from plant-to-plant by many species of aphids. Aphids only retain the ability to transmit these viruses for very short periods of time (minutes to a few hours). Thus, spread is often very rapid and local.
How does the disease spread from one plant to another?
All viruses that spread within their host tissues (systemically) can be transmitted by grafting branches or buds from diseased plants on healthy plants. Natural grafting and transmission are possible by root grafts and with parasitic dodder (Cuscuta species). Vegetative propagation often spreads plant viruses.
What kills viruses in plants?
One of the most common vectors of viruses are insects. Insects feed on infected plants and transmit the viruses to healthy plants when they feed again. Other ways include plant propagation, contact by humans, and infected seed. Unfortunately, once infected, there are no chemical treatments for eliminating a virus.
Can plant viruses be cured?
