Plant diseases can spread through various means, including:
Airborne transmission: Pathogens can be carried by the wind and infect plants over long distances. Waterborne transmission: Pathogens can spread through water, including rain, irrigation, and surface runoff. Vector transmission: Insects, animals, or humans can carry pathogens from one plant to another. Soil transmission: Pathogens can persist in the soil and infect plants through their roots.
