Blotter method was more accurate than PDA method for detect seed-borne fungi on watermelon, melon and squash seeds respectively. Seed-borne fungi were dominant in seed testa followed by cotyledons. Seed transmission by water agar method, clearly indicated transmission of Fusarium solani, Macrophomina phaseolin, Rhizoctonia solani from watermelon, melon and squash seeds to seedlings. Typical symptoms of the diseases were appeared on plants like vascular wilt, charcoal rot, stunted growth, brown spots and root rot on hypocotyls and cotyledons. F. solani was transmitted through roots, stems and shoots in watermelon and melon but through stems only in squash, while M. phaseolina and R. solani were transmitted through roots, stems and shoots in watermelon, melon and squash |
