Host: Abelmoschus esculentus (L.) Moench (bhendi, okra)Disease name: Bhendi yellow vein mosaicPathogen name: Bhendi yellow vein mosaic virus
Bhendi (okra) leaf severely infected with Bhendi yellow vein mosaic virus.
Bhendi yellow vein mosaic was first reported in okra plants in 1924 in India and Sri Lanka. The symptoms include alternate green and yellow patches, vein clearing, and vein chlorosis of leaves. The yellow network of veins is very conspicuous, and vein and veinlets are thickened. In severe cases, the chlorosis may extend to the interveinal area and may result in complete yellowing of leaves. Fruits are dwarfed, malformed, and yellow green. The whitefly Bemisia tabaci (Genn.) sibling species group is the insect vector. The whitefly vector reproduces to significant numbers during the summer season when it transmits the virus between okra plants. The causal agent is the single-stranded DNA Bhendi yellow vein mosaic virus (BYVMV), which is associated with a beta satellite, both of which are required for infection. BYVMV belongs to the genus Begomovirus, family Geminiviridae.
Management strategies: Infected plants must be collected and burned. Insecticides can be sprayed for vector control. Moderately resistant cultivars, Co3 and Kranthi, are available.
