The answer is simply, no. Since plants are not a susceptible host for the virus that gives us the flu. VIruses are incredibly host specific, so we can‘t get sick with a plant virus and plants can‘t get sick with an animal virus. However, that doesn’t mean we don’t “spread” viral diseases to plants.
Q. Is dwarfing a viral disease?
Barley yellow dwarf (BYD) is a worldwide virus disease of our most important grasses, including wheat, rice and maize. In the mid-1900s, the yellowing symptoms, transmission by aphids, and lack of transmission by rubbing (mechanical inoculation) differentiated BYD from many other plant virus diseases.
