Anthracnose of banana is caused by Colletotrichum musae and is one of the most serious diseases of ripe banana. Plant-mediated biological synthesis of nanoparticles is gaining importance in recent years due to its simplicity and eco-friendliness in the management of plant diseases. Present investigation was carried out during 2015-16 in department of plant pathology, UAS, Dharwad on management of banana anthracnose by using green nanoparticles. Efficacy of green nanoparticles (ajwain and neem leaf extract) of copper, silver, nickel and magnesium has been studied in vitro at different concentrations against C. musae. Silver-Neem nano particles (Ag-Neem Nps) were tested in vivo for their bio-efficacy against anthracnose as postharvest spraying at 0.01, 0.02, 0.05, 0.1 and 0.2 per cent concentrations. In vitro studies revealed that Ajwain-Mg NPs, Ajwain-Ni NPs at 0.2 per cent and Neem-Ag NPs at 0.1 and 0.2 per cent have shown complete inhibition of spore germination of C. musae. Spraying of Ag-Neem np at 0.2 per cent concentration recorded lowest disease severity (6.67 PDI)* which was on par with 0.1 and 0.05 per cent concentrations (8.89 PDI) and.
