BRAINCAKETransmission of Pathogens Between Plants
Plants cannot move around or expel droplets containing pathogens into the air.
Instead, the spread by direct transmission involves the contact between a healthy plant and any part of a diseased plant.
Indirect transmission is through soil contamination and vectors such as the wind, water, animals and humans.
