SUMMARY
The purpose of this seminar is to explain the biological control concept and
brown rot disease of potato and different means of biological control of
this disease and other diseases.

The brown rot disease of potato is worldwide disease that causes loss of
potato production. This seminar shows the symptoms of this disease in above
and under ground parts of potato plants. Also, it indicates the ways of
infection. The causal pathogen is a gram-negative bacterium called Ralstonia
solanacearum.

This seminar reveals the two strains of this bacterial pathogen, its races,
biovars and its classification. The epidemiology of this disease is
discussed.

The biological control of this disease is discussed in this seminar. The use
of different bio agents (phages actinomycetes, essential oil,
basidiomycetes, Organic amendments and plant residues) against R.
solanacearum and other plant pathogens is discussed in this seminar.
The internet discussion welcomes participants to join the forum on a very
wide range of methods in biological control of the disease. The background
paper provides a review of methods through manipulation of the environment,
host or use of antagonists, biological substances.
