ASSESSMENT OF PHEROMONE BASE IPM MODULE AGAINST YELLOW STEM BORER, Scirpophaga incertulas WALKER IN PADDY CROP
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 51
Abstract
Assessment of integrated pest management (IPM) modules against yellow stem borer (Scirpophaga incertulas Walker) in paddy cv. Rajendra Bhagawati was carried out at ten farmer’s field in Manjhi block, Saran district, Bihar in Kharif 2014 and 2015. Two IPM modules (M1 and M2) were conducted and compared with farmer practice. Components of module-1 were summer ploughing, timely transplanting, recommended dose of fertilizer (100N:60P:40K), spacing (20 cm x 10 cm), use of pheromone traps @ 20 traps/ha and module-2 summer ploughing, timely transplanting, recommended dose of fertilizer (100N:60P:40K) and spacing (20 cm x 10 cm), pheromone traps @ 20 traps /ha and single dose of cartap hydrochloride 4G (750g a.i./ha ) at economic threshold level showed their superiority over farmer practices. The Mean IPM modules-1 and 2 resulted increased grain yield 34.05 q/ha and 36.37 q/ha respectively over farmers practices i.e. 23.48 q/ha. The result also proved that benefit cost ratio of tested M1 and M2 over farmer’s practice i.e., 1.04, 1.06 and 0.98, respectively.
