Protecting Tomato Seedlings from Infection with Pathogenic Fusarium Oxysporium Using Rosemary Oil and Nano-Chitosan

Year: 2025

Type: article

Abstract: The investigation aimed to evaluate the effectiveness of rosemary oil (Rosmarinus officinalis L.) and regular and nano chitosan in reducing the severity of tomato seedling infection caused by Fusarium oxysporium, as well as evaluating some growth parameters and chemical properties. The results of the study showed that all treatments achieved a significant increase in germination rates and protection of tomato seeds and seedlings from infection by the disease before and after emergence, as well as reducing the severity of infection compared to the treatment with the pathogenic fungus. The treatment of extracted rosemary oil and nano and regular chitosan in the presence of the pathogen reduced the severity of infection to 9.38%, 6.75%, and 23.56%, respectively, compared to 70.34% in the pathogen treatment. The effect was also positively reflected on the fresh and dry weight of the shoot and root system. The used factors proved their efficiency in inducing systemic resistance in tomato plants by increasing the activity of the peroxidase enzyme and phenols in the plant leaves
