Assessing the impacts of safer management strategies for okra yellow vein mosaic virus (OYVMV) and its white fly vector with emphasis on under-storey repellent crop

The approach using components like yellow sticky trap, repellent crop (coriander), plant sanitation, periodic removal of YVMV infected plants and plant fractions (leaf extract of rose apple and neem oil) worked well by effectively arresting the disease development and vector population build up. Besides one application each of emamectin benzoate and spinosad, was sufficient to produce a conclusive effect on the vector and YVMV disease development and resulted in good yields. Only 2.5 -2.9% YVMV infected plants and 0.8 -1.1 white fly/leaf were recorded on 30 days after sowing. Thereafter, both the vector and the virus were wiped away from the plants under these treatments.
