Viral Disease

Whitefly acts as a vector for infection.

The disease infects at all the stages
of crop growth and severely reduces growth and yield. The disease is transmitted by white fly. The characteristic symptoms of the disease are a homogenous interwoven network of yellow veins enclosing islands of green tissues. Initially infected leaves exhibit only yellow coloured veins but in the later stages, the entire leaf turns completely yellow. In extreme cases, the infected leaf become totally light yellow or cream coloured and there is no trace of green colour. At times, enations (raised structures) are observed on the under surface of infected leaf. Plants infected in the early stages remain stunted. The fruits of the infected plants exhibit pale yellow colour, deformed, small and tough in texture. As tool of cultural insect control plating banana plants as a barrier around the okra cultivation one or two months before planting might help.
