Abstract

      The aim of the study was to protect tomato plants from root and stem rot disease caused by the fungus Fusarium solani under test using regular chitosan and threonine (Thr) at concentrations of 0.5, 1.0, 1.5, and 2.0 g L-1 for each. This was done by measuring the intensity of certain growth parameters and peroxidase activity. Compared with the control treatment, the results showed that all plant treatments, including chitosan and threonine, protected tomato plants by inducing systemic resistance to root and stem rot disease. The plant defense mechanisms were activated as evidenced by increased peroxidase activity, which typically results in growth parameters such as increased length and weight of both fresh and dry vegetable groups with statistically significant differences compared to the pathogenic fungus treatment.
