Fungi
Fungi are among the most
widespread organisms on earth. Many
fungi are free living in soil and water while some forms parasitic relationships
with plants and animals. Plant diseases caused by fungi reduce the crops, alter
the flowers and fruits and finally cause the death of the plant. Examples of
fungi with the plant diseases they cause are Magnaporthe grisea (rice blast),
Thielaviopsis spp. (canker rot), Ustilago spp. (smuts ) and Phakospora
pachyrhizi (soybean rust).
