Effect of organic treatments on total phenol, Saponin and flavonoids in leaf spot infected fenugreek leaves

Abstract

Fenugreek (Trigonella foenum graecum L.) is an important medicinal crops cultivated throughout the world. Increasing demand of medicinal plants for the pharmaceutical industry, is required to boost the production of fenugreek with minimized the infection of diseases which reduces the huge yields. therefore present study was conducted to determine the effect of organic treatments on secondary metabolites. The total phenol in healthy leaves was maximum in seed treatment with cow urine@10 %( 12.24µg/g) followed by foliar spray of cow urine (11.47 µg/g) and panchgavya (11.37 µg/g). Flavonoid content was observed highest in cow urine (4.11 µg/g) and lowest in vanaspativash (2.17 µg/g). Whereas saponin content was recorded higher in seed treatment withcow urine (15.33 µg/g) and lower in foliar spray of vanaspativash (13.06 µg/g). Percent disease intensity of Cercospora leaf spot was 33.29% in seed treatment with mixture of vanaspativash, cow urine and cow dung slurry and maximum in control 41.34%.
