Abstract :
Antifungal potential of aqueous extracts of Brassica campestris L. was evaluated against three plant pathogenic fungi namely Fusarium oxysporum Schlechtend, Drechslera australiensis (Bugnic) Subram B.L. Jain. and Macrophomina phaseolina Tassi Goid. Aqueous extract of leaves of B. campestris was prepared and added in the potato dextrose broth medium to get 2, 4, 6, 8 and 10% concentrations (w/v). Growth of all the test fungi was significantly suppressed by higher concentration of aqueous extract of root and shoot of the test plant. Maximum biomass reduction (44%) was due to 10% root extract against M. phaseolina followed by 30% reduction in biomass of F. oxysporum. Minimum reduction in biomass (14%) was recorded in D. australiensis at 10% concentration. Shoot extract also reduced fungal biomass which was 38% in M. phaseolina, 26% in F. oxysporum and 9% in D. australiensis.
