T
he use of bio-based nanomaterials in agriculture is
receiving more attention due to their non-toxicity, bio-
degradability, specificity and broad range of action with
improved function. Chitosan, a polymer is used in agriculture
for improved growth and protection of crops from various
biotic stresses. However, the size limits its wide application
and hence, chitosan nanoparticles were synthesized.
Synthesized chitosan nanoparticles were characterized using
FTIR, DLS, TEM and XRD analyses. They were used to improve
growth and yield of fingermillet plants and to protect them
from phytopathogenic fungus. Foliar application of chitosan
nanoparticle promotes growth of fingermillet plants and
induced ROS accumulation, peroxidase activity in treated
leaves. Treated plants challenged with blast fungus showed
protection. High accumulation of peroxidase correlates with
decreased blast disease symptom appearance in treated
plants. Treated plants showed high accumulation of ROS and
peroxidase which might be the reason for suppression of
blast disease incidence.
