Cu- chitosan nanoparticles: As an antibacterial agent against bacterial pustule disease of Soybean [Glycine max (L.)]

Abstract

Indiscriminate use of pesticides and fertilizers causes loss of biodiversity, environmental pollution and emergence of agricultural pests and pathogens. Chitosan is a biocompatible, biodegradable and nontoxic polymer with various applications. In the present investigation, the efficacy of Cu-chitosan nanoparticles (NPs) to boost defense responses against Bacterial Pustule disease of soybean activity were evaluated. Cu-chitosan NPs treated plants showed significant defense response through higher activities of antioxidant (SOD and POD) and defense enzymes (PPO and PAL). Significant control of pustule disease of soybean was recorded at 0.06% concentration of Cu-chitosan NPs treatments in pot and field condition. The potential of Cu-chitosan NPs is this study anticipated that developed NPs could be further exploited in large scale experiments.
