Describe conditions under which bacterial infection of plants can become prevalent?
What will be an ideal response?
Bacterial diseases thrive when surface moisture is present. A pathway for this type of infection is made
when plant material is damaged or stressed. Leaves may be torn or stems may be lacerated during
installation, maintenance or by malevolence. These wounds become entry ports for bacterial infection.
Already sick plants are also prone. Numerous bacterial leaf spots and bacterial blights are numerous
and proliferate in humid, warm environments.
