Talaromyces flavus is also a fungal antagonist which
has been used in the biological control of several plant
pathogenic fungi. Talaromyces flavus has been used on
Verticillium dahliae which is the causal agent of wilt disease
on several plants (Naraghi et al. 2006; Naraghi et al.
2010; Naraghi et al. 2013). This antagonistic fungus has
also been used in a recent study conducted by Kakvan et
al. (2013) for controlling the damping-off disease of sugar
beet, and has produced promising results.
The majority of antagonistic microorganisms, including
fungi, perform well in controlled environmental conditions
but fail to do so in the field. This failure is due
to several reasons including inappropriate application
methods. One of the most important reasons for the failure
of fungal antagonists in the field may been related
to the lack of the use of a proper formulation. The most
practical method for the application of biocontrol agents
in the field is to develop and prepare powdery formulations
for farmers to use them as seed treatment, particularly
for controlling seed and root diseases. Studies have
shown that the efficacy of some microbial antagonists in
biological control of different plant diseases has been preserved
after they have been mixed with organic and inor
