In Vitro Seed Treatment of Fungicides for the Control of Seed Borne Fungi of Soybean Variety Durga

Soybean (Glycine max L.) are associated by several seed borne pathogens. These fungi were detected by the methods as recommended ISTA. Fungi such as Aspergillus flavus, Aspergillus niger, Aspergillus fumigatus, Alternaria tenuis, Fusarium oxysporum, Penicillium notatum, Sclerotium rolfsii, Mucor mucedo Curvularia lunata Cladosporium herbarum and Drechslera oryzae, and Rhizopus stolonifer were isolated from the Soybean variety Durga. Eeffect of different fungicides like Thiram, captan and Copper oxycholoride on the incidence of seed borne fungi and their effect on seed germination were evaluated. The seed treatment by the fungicides showed that Copper oxycholoride increased the germination percentage and reduced seed mycoflora. Thus the seeds are treated with fungicides to eliminate the seed borne mycoflora of Soybean.
