Abstract

An experiment was conducted to evaluate the efficacy of aqueous extracts of certain plants with reported antiviral activity and biocontrol agents for the management of Chilli leaf curl virus (ChiLCV) disease naturally infecting chilli. It was observed that seed treatment followed by foliar sprays at 15 days interval using 10% Azadirachta indica and Mirabilis jalapa extracts significantly reduced the disease incidence as well as severity. Also, three treatments, namely A. indica, Pseudomonas flourescens and Bacillus subtilis were found to efficiently check the number of whiteflies. Plant height was also found to be significantly higher in plants treated with A.indica and M. jalapa. Bougainvillea spectabilis and PGPR mix II treated plants. The presence of ChiLCV in the diseased plants was confirmed by performing PCR with virus specific primers.
