Author(s):
Vinod Chouhan and Ashwani Kumar
Abstract:
Nine phytoextracts and five non-conventional chemicals were evaluated against Bipolaris oryzae (causal agent of brown leaf spot disease of rice) under in vitro and field conditions. Out of nine phytoextracts, evaluated under in vitro conditions, garlic cloves extract inhibited the mycelial growth of fungus by 95.04% followed by neem (84.85%) and calotropis (78.79%) leaf extracts at 30% concentration. Five better phytoextracts were also evaluated as foliar spray under field conditions and the maximum per cent disease control was found in garlic cloves extract treated plots (15.04%). Among five non-conventional chemicals ferric chloride was found superior in which per cent disease control was observed as 31.28% followed by magnesium sulphate.
