“…Similar results were given by Sarkar et al (2018) who reported that all the growth and yield parameters were significantly affected due to viral complex resulting in yield loss of 60 per cent at 75 per cent disease incidence. These results were in accordance with Kumar and Kumar (2017) who also reported that there was yield reduction due to the viral complex infection.…”

Three different modules were formulated and tested for the integrated management of the chilli viral complex at two different locations. Out of the three modules, the disease incidence was significantly less in module- 2 during both the years consecutively, which recorded 27.2 per cent during Rabi 2019-20 and 25.2 per cent during Rabi 2020-21 respectively. The correlation analysis for the whitefly population with weather parameters during Rabi 2019-20 and 2020-21 indicated that there existed a positive and significant correlation of whiteflies with minimum temperature, morning humidity and wind velocity; but there was a negative correlation with evening relative humidity and sunshine hours. In the present study, there was a significant increase in the intensity of the disease (viral complex) and there was a corresponding decrease in the yield, yield attributes of the chilli crop. The results markedly reported that there was a significant difference between the CBR of different modules in correspondence with the disease incidence which had a remarkable influence on the yield and yield attributes hence on the CBR. With the help of the present study it was evident that module 2 has lower cost of production along with enhanced yield and a profitable CBR.

“…The first recognizable symptoms of the disease were noticed when the crop was 75 days old in case of direct sown, and 20-25 days in transplanted crop. The virus infected leaf samples were collected and visually diagnosed as upward leaf curl, mosaic, puckering, yellowing, vein banding and shoe string [7,8].…”

“…The pathogen invades roots, multiplies, spreads in the root and stem vascular systems, and blocks the circulation of water and nutrients ( Miller, Rowe & Riedel, 1986 ). Recent assessments in the coastal zone of Odisha’s chilli-growing regions revealed that, in addition to chilli leaf curl disease, wilt disease is also heavily affecting yields ( Sarkar et al, 2018 ).…”

In the eastern coastal regions of Odisha, wilt caused by Fusarium oxysporum f. sp.capsici is an extremely damaging disease in chilli. This disease is very difficult to manage with chemical fungicides since it is soil-borne in nature. The natural rhizosphere soil of the chilli plant was used to isolate and test bacterial antagonists for their effectiveness and ability to promote plant growth. Out of the fifty-five isolates isolated from the rhizosphere of healthy chilli plants, five isolates, namely Iso 01, Iso 17, Iso 23, Iso 24, and Iso 32, showed their highly antagonistic activity against F. oxysporum f. sp. capsici under in vitro. In a dual culture, Iso 32 (73.3%) and Iso 24 (71.5%) caused the highest level of pathogen inhibition. In greenhouse trials, artificially inoculated chilli plants treated with Iso 32 (8.8%) and Iso 24 (10.2%) had decreased percent disease incidence (PDI), with percent disease reduction over control of 85.6% and 83.3%, respectively. Iso 32 and Iso 24 treated chilli seeds have shown higher seed vigor index of 973.7 and 948.8, respectively, as compared to untreated control 636.5. Furthermore, both the isolates significantly increased plant height as well as the fresh and dry weight of chilli plants under the rolled paper towel method. Morphological, biochemical, and molecular characterization identified Bacillus amyloliquefaciens (MH491049) as the key antagonist. This study demonstrates that rhizobacteria, specifically Iso 32 and Iso 24, can effectively protect chilli plants against Fusarium wilt while promoting overall plant development. These findings hold promise for sustainable and eco-friendly management of Fusarium wilt in chilli cultivation.
