Symptoms of damage:

1. The leafhoppers attack all the stages of the plant. Both adults and nymphs cause direct damage by sucking plant sap leading to stunted growth and reduced tillering.

2. At high population levels their feeding results in the drying of the plants and the infested paddy fields appear blighted. Infestation at the time of panicle emergence affects grain formation.
