Abstract
Abstract BACKGROUND Silver oxide (Ag 2 O) nanostructures were fabricated and their ability to induce antifungal activity against Macrophomina phaseolina , which causes charcoal rot disease in strawberries, was evaluated under laboratory, greenhouse and field conditions. A real‐time quantitative polymerase chain reaction was used to monitor expression of defense‐related genes, which is essential to evaluate the potential of the manufactured nanoparticles to promote strawberry resistance against charcoal rot. The effect of Ag 2 O nanoparticles on growth characteristics in strawberry plants was also studied. RESULTS The results showed that Ag 2 O significantly inhibited M. phaseolina growth compared with untreated controls under in vitro conditions. Strawberry plants treated with Ag 2 O showed a significant decrease in the severity of charcoal rot disease in the greenhouse compared with untreated plants. Strawberry plants treated with Ag 2 O nanoparticles expressed defense gene ( PR‐1 ) involved in the salicylic acid signaling pathways at levels three to five times higher than in the control group. Ag 2 O nanoparticles significantly improved the growth and yield of the strawberry crop. CONCLUSION Use of Ag 2 O nanoparticles can be considered a new strategy to control M. phaseolina and this is the first report of this effect. © 2022 Society of Chemical Industry.
