Abstract:
Sandal (Santalum album L.) a economically valued medicinal tree species affected by powdery mildew disease causing huge seedling mortality in the nursery. To identify the best systemic fungicide against, In vitro evaluation of two concentrations (100 ppm and 300 ppm) each of six different systemic fungicides were tested against conidial germination inhibition of Pseudoidium santalacearum causing powdery mildew by following spore germination method. Maximum inhibition of conidial germination was recorded in 300 ppm of Hexaconazole 5% SC (51.48%) followed by Propiconazole 25% EC (300 ppm) [46.33%]. Azoxystrobin 23% EC at 100 ppm resulted least conidial germination inhibition (20.12%). Maximum mean per cent inhibition was in Hexaconazole 5% SC (46.41%) followed by Propiconazole 25% EC (42.35%) and minimum inhibition per cent was recorded by Azoxystrobin 23% EC (25.89%).
