Discussion

Field trial assessed insecticide efficacy against leafhopper in castor, suggesting Cyantraniliprole is most effective.

Cyantraniliprole significantly reduced leafhopper populations to 16.6 leafhoppers per 3 leaves per plant.
Seed yield increased with all treatments, with Cyantraniliprole yielding the highest at 2257 kg per hectare.
The incremental cost-benefit ratio for Cyantraniliprole was the best at 1:8.3, highlighting its economic advantage.
Profenofos, Thiacloprid, and Spinetoram were less effective than Cyantraniliprole in managing leafhopper infestations.

Madhuri et al. (2025) studied this question.
