Abstract: Field experiments was conducted for two seasons in two different locations of northern Karnataka to evaluate the efficacy of chemicals, bio control agents and soil amendment integrated in three management modules on incidence and management of fusarium wilt of chilli. The efficacy of these modules on plant growth and incidence of fusarium wilt was assessed. The experiments were conducted for two seasons in two different locations. The experiment was laid in randomized block design. Two varieties with differential disease reaction were taken for the experiment. Seed treatment of fungicides and bio control agents either alone or in combination was tested in nursery. Drenching of chemicals and bio control agents were made alone or in rotation with fungicides were done. The observations on plant growth parameters, disease incidence, per cent disease reduction, reduction in pathogen population and yield were recorded. Our results revealed that, significant increase in germination percent and plant growth parameters was recorded in module-III (adoptive module) with least death of the seedlings (9.04 and 8.96%). In the main field, module-III performed better with least disease incidence (15.80 and 12.67%) and highest yield (26.25 and 18.25 ton/ha) in both Sitara and Atirikta varieties. This module found best for two seasons in two different locations of Karnataka. The cost economics was also calculated and found that, highest cost benefit ratio (1:3.25 and 1:2.70 Rs) was obtained by following the adoptive module. There was significant reduction in pathogen population was also recorded from both the locations when compared with control treatment. Application of soil amendments like neem cake before transplanting also helps in controlling the disease and maintain soil health also.
