Effect of seed dressing fungicides and bioagent on survival of seed-borne fungi and shelf life of soybean.

摘要

Soybean seed showed association of 10 fungi belonging to nine genera viz., Alternaria, Aspergillus, Colletotrichum, Curvularia, Fusarium, Penicillum, Phoma, Rhizoctonia and Rhizopus. Among the fungicides and bioagent tested for their efficacy against seed-borne mycoflora to improve seed germination and plant health showed that fungal association with soybean, seed germination percentage, shoot, root length and seedling vigour index decreased as the storage period increased. Seed treatment thiram+carbendazim (1:1) 3 g/kg of seed was found superior in controlling the seed-borne mycoflora (0.50 to 0.0%), increasing the seed germination (85.00 to 79.00%), shoot (10.06 to 6.50 cm), root length (6.42 to 6.35 cm) and seedling vigour index (1400 to 936).
