Validation of pheromone based ipm module against yellow stem borer, Scirpophaga incertulas walker in basmati rice

Validation of integrated pest management (IPM) module against yellow stem borer (Scirpophaga incertulas Walker) in basmati was carried out at farmer's field in village Murchipur of Faizabad and compared with farmer's practices (Non-IPM) during wet seasons of 2007 and 2008. The IPM schedule with eight components viz., summer ploughing, early transplanting by 15^th July, clipping of seedling tips before transplanting, recommended doses of fertilizers (90N:40P:30K), plant spacing with 20cm x 10cm, mass trapping of yellow stem borer (YSB) with pheromone traps @ 20 traps ha⁻¹, proper drainage, and single application of cartap hydrochloride 4G (750g a.i. ha⁻¹) at economic threshold level showed their superiority over farmer's practices. The IPM module resulted 34–39% increase in grain yield with mean increase of 36.79% over non-IPM plots. The results also proved the cost effectiveness of tested IPM module over farmer's practice with 1: 1.92 cost benefit ratio.
