Fungicidal synergistic effect of biogenically synthesized zinc oxide and copper oxide nanoparticles against causing citrus black rot disease.

Citrus black rot disease being caused by is a major disease of citrus plants with 30-35% economic loss annually. Fungicides had not been effective in the control of this disease during last few decades. In the present study, antifungal role of green synthesized zinc oxide (ZnO) and copper oxide (CuO) nanoparticles (NPs) were studied against .
