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

8 of 11 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
