The disease is enation leaf curl of okra (caused by okra enation leaf curl virus). It is transmitted by whitefly Bemisia tabaci (Genn.).

Control measures:
1. Remove the infected plant and burn them to avoid further spread of disease
2. Use yellow sticky traps to monitor whiteflies population
3. If the whiteflies infestation is more spray suitable insecticides like Dimethoate (0.05%) or Monocrotophos (0.02%) at 10 days interval (two sprays).

Dr. Ravishankar Narayana commented,
It is always good to use two different kind of insecticides to avoid resistant development in white flies. Diafenthiuron 50% WP is also a reasonable insecticide which is affective against mites, aphids and white flies. The main mode of action of this insecticide is it kills nymphs and adults by contact or stomach action. It is advice to spray full crop canopy to get good result.
