Statistical analysis
Data for mycelial growth, sporulation, and spore germination were trans formed into relative values to compare percentage inhibition effect of the extracts with the control. Relative growth, necrotic lesion diameter, disease severity score (1±5) , percent age defoliation and percentage wilt symptoms data were analysed according to general linear model procedures of the Statistical Analysis System (SAS Institute, 1989). Fischer -protec- ted LSD test and the Duncan multiple range test of mean separation were performed when the ANOVA showed significance.
