| dc.description.abstract | Soybean (Glycine max (L.) Merrill), a native of eastern Asia or China is an important pulse crop causing anthracnose, purple stain disease of soybean is one of the cause of lowered seed quality. Assessment of seed quality losses due to purple stain disease, detection of pathogen using different incubation methods, seed transmission and effects of different seed treatments with chemicals, botanicals and bioagents were studied. F. oxysporum was repeatedly isolated from purple stained seeds when subjected to different incubation methods. Czapek‟s Dox Agar medium yielded highest incidence of F. oxysporum followed by blotter method. The germination per cent and vigour index was decreased in infected seeds. These fungi resulted in more abnormal seedlings and seed rot. Germinating seedlings showed chlorosis on cotyledonary leaves followed by necrosis. Bavistin showed good germination per cent, more normal seedling and high vigour index at 500 ppm concentration. Amongst the botanicals, garlic extract reduced the fungal infection and decreased seed rot. However, these botanicals were significantly inferior to all chemical treatment used for seed treatment. | en_US |
