Characterisation and in-vitro Control of Curvularia lunata , the Causal Agent of Brown Leaf Spot Disease of Rice in Ghana

Irrigated rice production is common in the coastal savannah zone of Ghana. Recent observations have shown incidence a new leaf spot disease some basins area. Research was carried out to determine and severity area, identify causal agent using its cultural morphological features, complemented with phylogenetic studies internal transcribed spacer region. Also, effect selected fungicides an antagonistic Trichoderma harzianum on mycelial growth fungus determined vitro. The found all major growing districts severities ranging from 22.6 50.9%. Curvularia lunata identified as disease. Carbendazim, Nordox Mancozeb, totally depressed whiles T. inhibited fungus. These organism potential for control field.
