Spots appear on leaves, blossoms, fruits and stems.

Which is an example of a plant pathogen?
Pathogens are capable of producing infection and causing a disease. Fungal spores, bacterial cells, virus particles, and nematode juveniles or adults are examples of plant pathogens. Fungi are the most common plant pathogens. Role of the environment
What kind of bacteria are found in plants?
Arthrobacter, Pseudomonas, Rhizobacterand Rhodococcus. Agrobacterium tumefaciens, A. rubiand A. vitisalone are responsible for galls in over 390 plant genera worldwide. Galls of these genera have been referred to as crown gall, crown knot, root knot and root gall. Species of these bacteria are thought to be present in most agriculture soil.
