Sesame (Sesamum indicum L.) is one of the most ancient oilseed crop and rich source of oil, protein, calcium as well as phosphorus, which is cultivated throughout Pakistan. Different pathogens affect the sesame crop and causing diseases including some post-harvest and storage fungi causing serious losses in production. These seeds borne fungi causes heavy damage by decreasing seed germination. Infected germinated seeds do not grow properly which increased the chance of seedling concision and pre or post emergence diseases consequences into inhibited growth and yield losses. By considering the above evidences the current research is intended to determine the seed borne fungi related with sesame seeds and their management. For this purpose seed samples were collected from seed market of Faisalabad and Ayub Agriculture Research Institute (AARI) (250 g/sample). These seed samples were platted on blotter paper and agar plates. These plates were incubated at 25±2ºC and number of fungi were observed and identified with fungal colony color, sporulation type and relevant literature after 6-8 days of incubation. During management trials the evaluation of treated and non-treated seeds were done by using different seed dressing fungicides and plant extracts. These research trials were carried out under Complete Randomized Design (CRD) and the statistical significance between mean values were recorded using LSD test. During the detection experiments, Alternaria alternata, Fusarium moniliforme, F. oxysporum, A. tenuis, S. rolfsi, Cercospora sesami, Curvularia lunata, Macrophomina phaseolina, Aspergillus niger, A. flavus, A. ochraceus, A. versicolor, A. terreus, A. candidus, Haplosporangium sp., Penicillium citratum, Rhizopus nigricans, and R, stolonifer were isolated from local variety of sesame seeds. Among all the seed health test methods, standard blotter method is most superior for detection of seedborne fungi over the other methods.
