Abstract
Current study was aimed to analyze the consumption of nutrients against Bacterial leaf spot of spinach caused by Pseudomonas syringae pv. spinaciae through leaf analysis. It was performed after the application of treatments (Streptomycin sulphate and Acacia nilotica extract) according to CRD under greenhouse conditions. The leaf analysis revealed the maximum concentration of nutrients was recorded in healthy plants (positive control) followed by Streptomycin sulphate and Acacia nilotica extract as compared to diseased plants (negative control). This showed the Pseudomonas syringae pv. spinaciae depleted more plant nutrients in diseased plants as compared to healthy plants and treatments. This was also revealed by the application of treatments (Streptomycin sulphate and A. nilotica) that there was less consumption of nutrients as compared to negative control. The increased ionic contents in healthy and treated plants showed the strengthened biochemical and physiological processes of the host plants which helped to avoid the spread of pathogen.
