On the basis of experimental findings, the Front Line Demonstration (FLD) were conducted by selecting 2.0 ha land of 4 farmers from one villages in each of seven Krishi Vigyan Kendra of Bihar Agricultural University, Sabour, Bihar during summer season, 2017. The field trials were carried out with three treatments in randomised block design (RBD) in (0.5 ha land of each farmer). The result of Front Line Demonstration showed that the lowest infestation of insect pests viz, aphid, Rhopalosiphum nymphaeae L. (0.13/ 20 leaves), case worms, Elophila crisonalis W. (0.47/ leaves) & E. depunctalis W. (0.38/leaves) and Rib borer, Chironomous spp. (0.67/ leaves) and highest yield (26.09 q/ha), avoidable loss (20.16%), B.C. ratio (5.26:1) were found in plot having Seed treatment with imidacloprid 70 WS (@5 g/kg seed), Root dip treatment with imidacloprid 70 WS@ 5 g/ lt. water and three foliar spray of NSKE @ 5% and followed by slightly higher infestation of aphid, Rhopalosiphum nymphaeae L. (0.17/ 20 leaves), case worms, Elophila crisonalis W. (0.50/ leaves) & E. depunctalis W. (0.42/leaves) and Rib borer, Chironomous spp. (0.76/ leaves) and yield (25.67 q/ha) in FLD plot having treatment with thiomethoxam 25 WG (@5g/kg seed, Root dip treatment with thiomethoxam 25 WG @ 5 g/ lt. water and three foliar spray of NSKE @ 5%., both were non- significant to each other and significantly superior over farmers practice ( no insecticidal treatment) in effectively controlling the insect pests and gave highest yield. Both the management practices were found equally better than farmers’ practices. It may be concluded that seed treatment with imidacloprid70WS or thiomethoxam 25 WG @5 gm/kg seed and root dip treatment @ 5 gm/Lt of water for half an hour along with three foliar spray of NSKE @5 % effectively managed the insect pests in Makhana crop.
