Fungi are responsible for approximately two-third of the infectious plant diseases. There are many plant diseases caused by fungi, like mildew, smuts, rusts, etc.
Fungi belong to a large and diverse group of microorganisms.
They are actually cells that consist of a membrane-bound nucleus and are devoid of chlorophyll. They also have rigid cell walls. These fungi have a vegetative body, of which some parts extend into the air and others penetrate the substrate of the organisms that it grows on.
Fungi propagate through sexual as well as asexual methods and spread through spores that are produced in abundance. These spores are transmitted on plants through wind, water, soil, birds, and insects. Once one of your plants is infected by a fungus, it is important that you protect your other plants from the fungal infection.
Plant diseases that are caused by fungi reduce the crops, create markings, affect the flowers and fruits, finally causing death of the plant. Majority of the plant diseases, about 8,000 , are caused by fungi.
