Biological Control of Seed Mycoflora of Groundnut Using Extract OfOcimumSanctum L.
ABSTRACT:In present investigation study of fungi associated seeds of groundnut variety local revealed presence of 20 fungi on the seed surface. Seed borne fungi like Aspergillus flavus, Alternaria Curvularialunata, and Fusarium moniliforme were found. These fungi were found to be responsible for the loss in dry weight (dwt), loss in total protein content (TPC), total fat content (TFC) and total starch content (TSC) of the seeds of groundnut variety. The culture filtrates (CF) of the predominant seed borne fungi where found to be more inhibitory for seed germination (CG) and Seedling emergence (SE) Of the test cultivar, therefore the root , stem and leaf extracts of ocimum sanctum L. were used for the biocontrol of the seed mycoflora of groundnut. The test extract were found to be more inhibitory for the incidence of seed mycoflora (ISM), for germination and seed growth of seed borne fungi. Also found stimulatory for the SG and SE of the groundnut.
