Abstract:
The experiment entitled “Effect of fungicides, bioagents and botanicals against seed borne microflora of soybean in-vitro” was conducted at Department of Plant Pathology and Agriculture Microbiology. The experiment was laid out in CRD design with four replication and three treatment. The treatment Carbendazim + mancozeb (0.2%) found most effective as compared to vitavax, recorded 0 percent incidence of internally and externally seed borne pathogens. Among the bioagents Trichoderma harzianum recorded 2, 3, 2, 2 and 1 percent incidence of Fusarium oxysporum, Fusarium moniliforme, Macrophomina phaseolina, Alternaria alternata, Colletotrichum truncatum as against in the control treatment. Among the botanicals Garlic bulb extract showed 1, 3, 3, 2 and 2 percent incidence against these pathogens. Among the bioagents Trichoderma harzianum (0.6%) showed 3, 4, 3, 4, 3, 2, 1, 2 and 2 percent incidence of externally seed borne pathogens Aspergillus flavus, Aspergillus niger, Aspergillus candida, Curvularia lunata, Cladosporium sp., penicillium sp., Phoma medicaginis, Botrytis cinerea, Mucor sp. as against the control treatment. Among the botanicals, Garlic bulb extract recorded 3, 2, 3, 0, 0, 2, 1, 2 and 1 percent incidence of these pathogens as against the control treatment.
