Different biotic defense inducers such as, red seaweed extract (Kappaphycus alvarezii), plant extracts (Mirabilis jalapa L. and Bougainvillea spectabilis Willd.), biocontrol agents (Trichoderma harzianum and Pseudomonas fluorescens) and other defense inducing biomolecules viz., synthetic nucleoside, chitosan and virex-H were tested for their efficacy on Cucumber mosaic virus (CMV) infection in Chilli var. Pusa Jwala during Kharif2016- 17and Kharif 2017-18under field conditions. Results showed that a significantly less PDI ( %) and AUDPC () was observed in plants treated with Chitosan () with enhanced plant height ( cm), number of branches ( no.), number of fruits per plant ( no.), individual fruit weight ( g), fresh fruit yield ( ), fresh weight ( ), dry weight ( ). Significant differences among the treatments by reducing the CMV disease with increased growth and yield was observed and is found superior over the untreated control. | Management of cucumber mosaic virus (CMV) disease in chilli through biotic defense inducers
