Inhibitory effect of Caesalpinia spinosa leaflets crude extract on Fusarium solani and Phoma tarda

In order to evaluate the plant extract effect on the in vitro growth of Fusarium solani and Phoma tarda, hexane crude extract from spiny holdback (Caesalpinia spinosa) leaflets was obtained and incorporated into potato-dextrose-agar (PDA) at 2204 mg L, 4460 mg L, 6370 mg L, 7644 mg L and 16179 mg L concentrations. The hexane crude extract inhibited mycelial growth at the range of 3,95% to 32,20% of P. tarda and 7,29% to 33,83% of F. solani, according to the extract concentration. It was demonstrated that the extract has antifungal activity and might be an alternative to physical or chemical control methods of fusariosis disease in several cultivations and of Phoma spot on coffee plant leaf.
