The intial contact of pathogen with a site of plant where infection is possible

can occur through various means such as wind, rain, insects, or direct contact with contaminated surfaces. Once the pathogen comes into contact with the plant surface, it may enter the plant through natural openings such as stomata, wounds, or through direct penetration of the plant cell walls. This initial contact is a crucial step in the infection process as it allows the pathogen to establish itself within the plant and begin replicating, ultimately leading to disease development.
