Abstract:
Aspergilus flavus is the most
common seed born fungus that deteriorates
the seed quality and minimizes the export
value of the rice all over the world.
Fungicides are the most successful and
commonly used way to manage any fungi
but more use of fungicides have resulted
evolution in the seed born fungi so efforts
are required off and on to stay ahead of the
fungal races. Keeping in view, the present
research work was conducted to evaluate
different fungicides against A. flavus and
their comparative efficacy upon the infected
rice seeds. Experiment was laid out in
completely randomize design with varying
concentrations of fungicides (20, 40, 60 and
80 ppm) under laboratory conditions.
Statistical results shown significant
reduction in mycelial growth and improved
the seed germination as well. The results
were significantly better when the
fungicides were used at 80 ppm, as
compared to low concentrations. Regarding
mycelial growth, Kumulus-DF and Cabrio-
Top were comparative to each other,
followed by Trimiltox-Forte, Cordate and
Copper oxychloride, while for the other
attribute of infected grain germination
Kumulus-DF proven better in comparison
with Trimiltox-forte and Cabrio-Top,
followed by Cordate and Copper
oxychloride.
