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.
