Field efficacy of insecticides against Amrasca biguttula biguttula (Ishida) incidence on Egg plant

The comparative efficacy of insecticides against leafhopper, Amrasca biguttula biguttula incidence on egg plant, was field studied. Among the insecticides tested four sprays with cartap hydrochloride 50SP at 0.05% + diflubenzuron 25WP @ 0.012% @ 10 days intervals commencing with 30 days after transplanting was found to be most effective in restricting leaf hopper population to a minimum (2.6/3 leaves) as compared with the population in untreated control (12.2/3 leaves). The combination of azadirachtin 0.03% at 0.09% + carbaryl 50WP @ 0.2% was found to be the next effective treatment against the sucking insect. The total fruit yield based upon four pickings also showed the superiority of the former treatment.
