Brinjal is one of the important vegetable crop cultivated widely in India. It is susceptible to many diseases like sclerotium rot/wilt, verticillium wilt, fusarium wilt and bacterial wilt and it is being attacked by several diseases of fungi and bacteria. The collar rot/wilt disease caused by Sclerotium rolfsii is an important constraint in brinjal production. Hence, an in vivo study was conducted to evaluate the bio efficacy of antagonistic bio-agents and fungicide chemicals against root rot/wilt disease of Brinjal at College of Agriculture, Bheemrayangudi during 2011–2012.during field studies three fungicides and two antagonist bio-agent were evaluated against the rot/wilt disease at various combinations by seed treatments and soil application at different concentrations. The roving survey was undertaken to know the incidence of different diseases of brinjal in different parts of the talukas in Yadgiri and Gulbarga districts. revealed among different bioagents and fungicides tested alone or in combination for the efficacy the seed treatment by Trichoderma (10gms/kg) along with soil application of Trichoderma (FYM enriched 1:100 kg/ha) at sowing significantly reduced Sclerotium rot by 16.76 PDI with increased yield of 30.64 tons/ha followed by Seed Treatment with Trichoderma (10gm/kg), followed by Soil drenching of Pseudomonas fluorescence 10gm/lit recorded 20.55 percent disease with increased yield of 27.46 tons/ha and Seed Treatment by Trichoderma at 10gm/kg reduced color rot up to 20.98 PDI with 26.47 tons/ha yield which is on par with soil drenching by Raxil (0.1%) has recorded less 23.26 PDI and higher yield 25.27 tons/ha when compared to control which recorded higher color rot incidence of 37.02 percent (Table 1) and minimum yield of 19.66 tons/ha. The survey revealed that Sclerotium rot was severe in all the talukas surveyed and disease incidence ranged from 2.0 to 16.90 per cent. While, Rhizoctonia rot ranged from 1.0 to 9.25 percent, Bacterial wilt ranged from 2.0 to 9.0 PDI. However, fungal leaf spot ranged 2.2 to 3.4 percent and Mosaic disease ranged from 3.0 to 14.80 percent in different parts of the Gulbarga and Yadgir districts.
