The
aim of the present study was to prepare Chitosan nanoparticles through biological method with high
antifungal
activities. Chitosan nanoparticles were prepared by the addition of anionic proteins isolated
from
Penicillium oxalicum culture to chitosan solutions. The formation of chitosan nanoparticles was
preliminary
confirmed by UV–vis spectrophotometric analysis. The physico-chemical properties of the
chitosan
nanoparticles were determined by size and zeta potential analysis, FTIR analysis, HRTEM and
XRD
pattern. The chitosan nanoparticles were evaluated for its potential to inhibit the growth of phy-
topathogens
viz., Pyricularia grisea, Alternaria solani, Fusarium oxysporum. It is evident from our results
that
chitosan nanoparticles inhibit the growth of phytopathogens tested. Chitosan nanoparticle treated
chickpea
seeds showed positive morphological effects such as enhanced germination%, seed vigor index
and
vegetative biomass of seedlings. All these results indicate that chitosan nanoparticle can be used
further
under field condition to protect various crops from the devastating fungal pathogens as well as
growth
promoters.
