The present investigation was conducted during July to December 2018 at Central Research Farm, SHUATS, Naini, Prayagraj as fruit and shoot borer is a major pest in brinjal causing severe damage to the crop in prayagraj. Regular use of chemical pesticides create problem in the natural ecosystem like environmental pollution, pest resistance and health hazard etc. Hence, the study was conducted to find out best combination of botanical along with chemical treatment. Eight treatments were evaluated against Leucinodes orbonalis i.e., Neem oil 2 mL/L, Garlic bulb extract 50 mL/L, Pongamia oil 5 mL/L, Neem oil 2 mL/L + Cypermethrin 10EC 1 mL/L, Garlic bulb extract 50 mL/L + Cypermethrin 10EC 1 mL/L, Pongamia oil 5 mL/L + Cypermethrin 10EC 1 mL/L, Cypermethrin 10EC 2 mL/L along with untreated control. Minimum per cent of shoot infestation, fruit infestation and highest B:C ratio were recorded in Neem oil + Cypermethrin with (15.04%, 10.62% and 1:8.10) followed by Pongamia oil + Cypermethrin (15.56%, 11.26% and 1:7.42), Garlic bulb Extract + Cypermethrin (16.04%, 12.33% and 1:6.86), Cypermethrin (16.70%, 12.82% and 1:6.69), Neem oil (17.99%, 13.00% and 1:6.37), Pongamia oil (18.62%, 13.66% and 1:6.13), Garlic bulb extract (19.65%, 14.66% and 1:5.20) and untreated control (25.67%, 20.70% and 1:3.10) respectively.
Leucinodes orbonalis, Benefit cost ratio, Brinjal, Efficacy, Botanicals
The highest yield and benefit cost ratio was recorded in Neem oil + Cypermethrin (check) (218.5 q/ha and 1:8.10) supported by Yadav et al. (2017) followed by Pongamia oil + Cypermethrin (198.6 q/ha and 1:7.12), Garlic bulb extract + cypermethrin (186.9 q/ha and 1:6.86), Cypermethrin (179.7 q/ha and 1:6.69), were best three among treatment and these can be used alternatively for the management of brinjal pests (Table 2). From the critical analysis of the present findings it can be concluded that different Botanicals with Cypermethrin pesticides like Neem oil + Cypermethrin, Pongamia oil + Cypermethrin, Garlic bulb extract + cypermethrin and Cypermethrin were showing good result against Leucinodes orbonalis and can be used instead of solo use of chemical insecticides which causes environmental and ecological dent. It also has potential to be included in integrated pest management.
