Abstract:
A field experiment was conducted to evaluate the efficacy of some insecticides against pod borer, M. vitrata infesting lablab bean. After first and second spray, it was revealed that the treatment Emamectin benzoate 5SG @ 0.002% at 3DAS proved to be best in reducing pod damage caused by M. vitrata by recording (3.25 per cent) and which was at par with Indoxacarb 14.5 SC @ 0.014% (4.11 per cent) and Profenofos 50 EC @ 0.075% (5.20 per cent). At 7 DAS revealed that the lowest (2.57) per cent pod damage was recorded in the plots treated with Emamectin benzoate 5SG @ 0.002%, it was at par with Indoxacarb 14.5 SC @ 0.014% (3.84 per cent) and Profenofos 50 EC @ 0.075% (3.92 per cent). The minimum mean per cent pod damage of two sprays at 10 DAS was recorded in the treatment of Indoxacarb 14.5 SC @ 0.014% (2.46 per cent), it was at par with Emamectin benzoate 5SG @ 0.002% (2.75 per cent) and Profenofos 50 EC @ 0.075% (3.72 per cent). At 14 DAS revealed that the treatment Emamectin benzoate 5SG @ 0.002% (1.72 per cent) proved to be the best treatment amongst all and next best treatments were Indoxacarb 14.5 SC @ 0.014% (3.62 per cent), it was at par with Profenofos 50 EC @ 0.075% (4.67 per cent).
From the overall mean per cent of pod damage with two sprays it was revealed that the treatment of Emamectin benzoate 5SG @ 0.002 per cent was effective (2.57 per cent) in reducing the pod damage and was at par with Indoxacarb 14.5 SC @ 0.014 per cent (3.51 per cent). The next best treatments were Profenofos 50 EC @ 0.075% (4.38 per cent), Lambda cyhalothrin 5 EC @ 0.003% (6.33 per cent), Dichlorvos 76 EC @ 0.11% (6.37 per cent) and Deltamethrin 2.8 EC 0.0025% (8.06 per cent). The highest (17.80 per cent) pod damage was recorded in the untreated control.
The treatment Emamectin benzoate 5SG @ 0.002% recorded the highest green pod yield (86.61 q ha-1) and was at par with Indoxacarb 14.5 SC @ 0.014% which recorded (84.10 q ha-1) green pod yield. The next best treatments were Profenofos 50 EC @ 0.075% recorded (81.80 q ha-1), followed by Lambda cyhalothrin 5 EC @ 0.003% (77.01 q ha-1) it was at par with Dichlorvos 76 EC @ 0.11% (76.42 q ha-1), Deltamethrin 2.8 EC @ 0.0025% (74.70 q ha-1). and Azadirachtin 1% @ 0.003% (73.52 q ha-1) green pod yield, respectively.
