Sesame ( Sesamum indicum  L.) is a major oilseed crop in Pakistan, possessing high nutritional and pharmacological properties. Sesame is highly susceptible to pathogenic fungi such as  Alternaria alternata.  In the present study, metabolites extracted from culture filtrates of  Alternaria alternata  using hexane, chloroform, ethyl acetate, and petroleum ether solvents were evaluated for activity on seed germination and seedling health of sesame. Seeds treated with solvent-extracted metabolites from culture filtrates of  A. alternata  showed low germination as compared to control. Maximum reduction in germination was reported in seeds treated with petroleum ether culture filtrate followed by ethyl acetate, hexane, and chloroform. Shoot length and root length were also reduced in seeds treated with petroleum ether culture filtrate followed by ethyl acetate, hexane, and chloroform. Seedling treated with solvent-extracted metabolites from culture filtrates of  A. alternata  showed various symptoms including chlorosis, necrosis, discoloration, and wilting. From the present study, it is concluded that  A. alternata  contains certain metabolites which can reduce seed germination and are destructive for seedling stage of sesame. This is a baseline study to evaluate highly active metabolites which can be managed further to decrease sesame yield loss.
