Question: What Is A Route Of Transmission?

How are diseases 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 are the main routes of transmission?

What are the 3 methods of infection control?

There are three types of transmission-based precautions: contact, droplet, and airborne. Contact precautions are used in addition to standard precautions when caring for patients with known or suspected diseases that are spread by direct or indirect contact.
