Online published on 18 May, 2022. Abstract A study on the development of biointensive module was carried out at Agricultural Research Station (ARS), Virinjipuram during 2017–19 against viral and phytoplasma diseases of brinjal. The module thus developed was tested in two locations viz, ARS farm, Virinjipuram and in farmers’ field at K.V Kuppam block of Vellore district to assess the performance of biointensive Integrated Disease Management (BIDM) module against the mosaic, little leaf disease and whitefly during Kharif2020. The results revealed that the BIDM was found superior in minimising the mosaic incidence in both locations tested and recorded 5.16 and 6.12 per cent also with lowest little leaf incidence. The lowest whitefly population was also recorded in bio-intensive module adopted plots when compared to farmers’ practice at all stages of crop growth. At 30 days after transplanting (DAT), the whitefly population of 4.45 and 3.77 Nos per plant was recorded at ARS, Virinjipuram and in farmers’ field. With respect to fruit yield, an adoption of bio-intensive module registered a significantly higher yield both at ARS farm (34.02 t/ha) and in farmers’ field (30.36 t/ha) coupled with higher benefit cost ratio of 5.84 and 5.18, respectively. Where as in farmers’ practice the lowest fruit yield of 31.71 t/ha with BC ratio of 5.57 at ARS farm and 25.68 t/ha of fruit yield with CB ratio of 1:4.43 in farmers’ field were recorded.
