Biosynthesis of nano- iron sulfate using fenugreek plant and evaluation of its activity against white mold disease on eggplant

Abstract

This study was conducted to evaluate the effectiveness of regular and nano-fenugreek seeds at three concentrations and the alcoholic extract of fenugreek leaves and seeds at three concentrations (400, 800, 1200) ppm in resisting the fungus Sclerotinia sclerrotiorum, which causes white mold disease on eggplant , The results showed the effectiveness of nano-fenugreek seeds and the leaves and seeds of the fenugreek plant in reducing the severity of infection with the disease, with significant differences from the treatment of the pathogenic fungus at a concentration of 3% for the nano-fenugreek and a concentration of 1200 ppm for the leaves and seeds of the regular fenugreek plant. The results also showed that all treatments had a positive impact on the growth parameters of the eggplant plant, represented by length. Plant, leaf length and width, and wet and dry weight of plants compared to the Treatment of pathogenic fungi.
