Abstract:
Chilli (Capsicum annuum. L) is one of the most important commercial crops grown worldwide for its vegetable and spice purpose. Cucumber mosaic virus (CMV) is found to be a serious and destructive virus in terms of incidence and yield loss in chilli. Survey was carried out in six chilli growing districts of Telangana state to assess the incidence of CMV in chilli for 2 consecutive years from 2017-18 and 2018-19. Major symptoms observed were mosaic, mottling, shoe string, leaf deformation and stunting of plants. The survey revealed the presence of CMV in almost all the fields that were surveyed and the disease incidence was 8.44 to 16.69%. The maximum disease incidence of 16.69% was recorded in Warangal District. DAC-ELISA was performed to confirm the presence of CMV in chilli and the infected plants exhibiting shoe string symptoms showed the highest absorbance value of more than 0.7 followed by leaf deformation (0.5).
