Abstract
Powdery mildew of chilli caused by Leveillula taurica (Lev.)Arn. is
major menace for chilli cultivation prevalent in chilli growing areas of
Kamataka. Survey work revealed that, the average disease severity was
found more in Bellary district (79.12%) followed by Gulbarga (75.63%)
and least in Belgaum (43.05%). The obsei-vations on loss estimation
revealed that, comparatively lower disease index with increase in dry chilli
yield and also maximum BCR was recorded in plots receiving three sprays
of Penconazole. Yield loss of 42.82 per cent was noticed due to powdery
mildew in unsprayed plots
