Abstract

The experiment was conducted during 2023 spring season, to evaluate the efficacy of synthetic and herbal insecticides in managing okra jassid (Amrasca biguttula biguttula) populations and their impact on crop yield and economic returns. The experiment was RCBD design with three replications. Total seven treatments were used along with control.  Different insecticides viz., Imidacloprid 17.8% SL, Thiamethoxam 25% WG, Lambda-cyhalothrin 5% EC, Neem oil (Azadirachta indica), Garlic extract (Allium sativum) and Eucalyptus oil (Eucalyptus globulus). Among the chemical insecticides, Imidacloprid 17.8% SL achieved the highest mean percent reduction of jassids population was observed (81.25%), with a corresponding yield of (3,200 kg/ha) and a cost-benefit ratio (CBR) of (12.57). while followed by Thiamethoxam 25% WG and Lambda-cyhalothrin 5% EC followed with jassid reductions of (77%) and (72.25%), yielding (3,150 kg/ha) and (3,050 kg/ha) and CBRs (13.38) and (13.12), respectively. Among the botanical insecticides, Neem Oil 5% was the most effective, reducing the jassid population by (65.75%), with a yield of (2,800 kg/ha) and CBR (7.39). while followed by Garlic Extract 10% (55.25%) and Eucalyptus Oil 5% (50%), reducing the jassid population, resulting in yields of (2,650 kg/ha) and (2,500 kg/ha), with CBR (6.47) and (4.61), respectively. The untreated control plot, with no significant jassid reduction, produced the lowest yield of (1,900 kg/ha). It is concluded that chemical insecticides provide superior pest control and higher yields compared to botanicals. Imidacloprid 17.8% SL was the most effective and is recommended for controlling okra jassids. Neem Oil is also suggested as a viable botanical alternative.
