Abstract
Powdery mildew caused by Erysiphe polygoni DC is one of the major constraints in the production of fenugreek. Farmers have to spray fungicides regularly for disease management. In order to find out the effective fungicides against Erysiphe polygoni experiment was carried out under in vitro. The relative efficacies of different fungicides were tested in different concentration. Various fungicides tested by spore germination inhibition technic for testing their efficacy, among them in non-systemic fungicide wettable sulphur, systemic fungicide propiconazole and ready-mix of fungicide tebuconazole + trifloxystrobin were found best against E. polygoni in vitro evaluation.
