The infected plants are stunted and have yellowish green to whitish green leaves.
There is excessive tillering and leaves became soft and droop slightly.
Root growth is also reduced significantly.
Chlorosis occurs on the leaves occasionally even spreading to the leaf sheaths.
Streaks may also form parallel to the leaf veins.
If plants are infected early they usually die before maturity and even if they do survive no panicles are produced or only a small number with no grains.
Management
Deep ploughing during summer and burning of stubbles.
Rice varieties like IR62 and IR64 are resistant to the disease.
The management practices followed for Rice Tungro Disease(RTD) may be adopted for this disease also.
Avoiding early planted rice will prevent an increase in vector density and proportion of virus acquired vectors.
Planting fallow rice fields with non vector hosts, ploughing fallow paddy fields and late-planting, synchronous planting or avoiding an overlap of early and late planted rice crops.
Remove weed hosts periodically. .
Crop rotation .
The vegetation on the bunds should also be sprayed with the insecticides.
Chemical Method: Vector control with any one of the following insecticides .
