Efficacy of some plant extracts in controlling seed-borne fungal infections of maize seeds.

Efficacy of various concentrations of plant extracts prepared from rhizome of turmeric, basil leaf, Scent leaf and lemon grass leaf in reducing seed borne fungi was evaluated on six varieties of maize (Zea mays) viz; DMR-LSR-Y,ART/98/SW5, DMR-ESR-Y, TZPB-ISR-W, SUWAN-ISR-Y and ART/98/SW6. Among the treatments, turmeric extract preparations (1:0, 1:1, and 1:2) and fungicide enhanced seed germination when compared to other treatments. The percentage reduction of fungal incidence achieved by crude extracts (1:0) varied from 87.00%-93.80% for turmeric extract, 76.50%-89.00% for scent leaf extract, 60.50%-85.00% for Basil extract and 80.00%-90.50% for lemon grass extracts. The percentage germination for crude extract (1.0) varied from 95.00%-100.00% for turmeric, 62.00%-100.00% for scent leaf, 80.00%-100.00% for basil and 85.00%-100.00% for lemon grass. The fungi isolated from naturally infected maize seeds includes Aspergillus flavus, Aspergillus niger and Aspergillus ochraceus. It was also found that turmeric extract was the most effective, closely followed by lemon grass while scent leaf and basil were the least effective in the control of seed-borne fungi of maize. This indicates that these botanicals have strong antimicrobial properties and should be explored in the treatment of seeds.
