Abstract


Onion is one of the most important commercial vegetable crops grown in Pakistan. It is valued for its distinct pungent flavor and is an essential ingredient for the cooking in many regions. In this study, seed born fungus was detected from infected onion seeds by using blotter paper method and agar plate method. Seed born fungus was detected by using different fungus detecting methods, consequence of seed born fungus on seed sprouting and integrated management of seed born mycoflora by different chemicals and plant extracts. During the evaluation of detection methods, the fungus incidence was observed at higher level in PDA method as compared to Blotter paper method. Seed treated with Hombre gave maximum seed germination and minimum recovery of fungi as compared to control germination and other treated seeds. While the seeds sown without treatment of any fungicide suspension showed the lowest germination. In study onion seeds were also treated with different plant extracts e.g. garlic, neem and Safeda. The maximum seed germination was observed in case of neem treated seeds. Other plant extract garlic and Safeda showed intermediate growth.

Keys words: Onion, seed borne fungus, plant extracts
