| Abstract | ||||
| Six typical isolates that showed microscopic characters of Macrophomina phaseolina were isolated from sesame root rot tissue collected from sesame plantations’ growing in El-Minya governorate. Pathogenicity tests revealed that isolate M3 was the most virulent in this topical. Thus, further identifications process were applied on isolate M3 using DNA profile. Phylogenic analysis assured that M3 isolate is M. phaseolina. An exogenous utilization of zinc oxide nanoparticles (ZnO-NPs) and/or peroxy acetic acid (PAA) were concerned for study their efficiency to inhibit sesame root rooting fungus M. phaseolina, sesame vegetative growth and their potential to control sesame root rot. Either ZnO-NPsor PAA showed antifungal activity. however, ZnO-NPs was more active against M. phaseolina than PAA. Sesame vegetative growth showed vigor index (VI) enhancement for single treatment of each compound tested and ZnO-NPs was better than PAA. Combining ZnO-NPs (0.1g/l) with PAA (0.1 g/l AA+1 g/l H2O2) was superior to increase vegetate growth. Moreover, substation sesame root rot reduction was addressed by single application of ZnO-NPs or PAA. Combining ZnO-NPs(0.1g/l) with PAA (0.1 g/l AA+1 g/l H2O2) gave the greatest efficiency than single application of each compound tested. | ||||
