Abstract: Fenugreek (Trigonella foenum graceum L.) is one of the most important spices crop grown in India. Powdery mildew caused by Erysiphe polygoni DC is one of the major constraints in the production of fenugreek. In order to find out the efficacy of various phyto extract against Erysiphe polygoni experiment was carried out under in vitro condition. The relative efficacy of seven different phytoextracts were tested in different concentrations and different time of interval 24, 48 and 72 hours, respectively. Out of seven phytoextracts tested, two phytoextracts showed more than 50% inhibition at all concentrations on different time interval. Garlic and neem leaf extracts found best in spore germination inhibition at all the concentrations on different time interval. The significantly highest spore germination inhibition (81.82%) was recorded at 20 per cent concentration of garlic followed by 20 per cent concentration of neem (79.47%) on 72 hrs after the treatment.
