Use of bioactive substances such as chitosan to con-
trol post-harvest fungal disease has attracted much
attention due to imminent problems associated with
chemical agents, which include development of public
resistance to fungicide-treated produce, and increasing
the number of fungicide tolerant post-harvest pathogens
and a number of fungicides that are still under obser-
vation [18]. Chitosan reduces the in vitro growth of
numerous fungi with the exception Zygomycetes, i.e the
fungi containing chitosan as a major component of its
