n this lecture I will introduce a report about my study entitled " Effect of the new antagonist
Aspergillus piperis
on germination
and growth of tomato plant and early blight incidence caused by
Alternaria solani
". The present work is considered the first
record of studying the ability of the new antagonist,
Aspergillus piperis
in decreasing the disease incidence of early blight
of tomato plant caused by
Alternaria solani
. The pathogen
A. solani
was isolated from naturally diseased tomato fruits and
identified genetically by sequencing of rRNA gene using ITS1 and ITS4 primers. For the field experiment, the toxicity of
spore suspension of
A. piperis
on germination of tomato seeds was performed using soaking and irrigation methods where
the germination percentage and vigor index were calculated. The results indicated that the irrigation method recorded better
results than soaking where the germination percentage was 81.81 % and vigor index was 794.37 related to that of control which
recorded 90.9% and 715.83 respectively. The values of vigor index indicated that, the spore suspension of
A. piperis
had induced
the plant growth. In the meantime, the spore suspension of
A. piperis
was applied on tomato leaflets by several methods to
reduce the incidence of early blight disease. The application of
A. piperis
spore suspension directly on the leaflets exhibited the
best result where the percentage of infection was 10.25 % to the control (25 %) after 4 days.
