Abstract

This article focuses on the use of copper nanoparticles (Cu-NPs) to control bacterial leaf blight (BLB) in rice caused by the pathogen *Xanthomonas oryzae* pv. *oryzae* (Xoo). The study demonstrates that Cu-NPs synthesized with sodium carboxymethyl cellulose effectively inhibit Xoo growth at low concentrations and significantly reduce disease incidence in rice seedlings compared to copper sulfate (CuSO4) and untreated controls. Additionally, Cu-NPs enhance rice growth parameters such as root and shoot length, chlorophyll content, and the activity of antioxidant enzymes linked to plant defense. These findings suggest that Cu-NPs offer a promising, eco-friendly approach to managing BLB while promoting rice plant health.
