A field trial was conducted to quantify the role of Integrated Pest management (IPM) against brown planthopper Nilaparvata lugens Stål. in the upland rainfed rice growing areas of West Bengal, India during 2002-03 and it was reevaluated during 2017-18. The trail comprised of three treatments viz. (a) Natural Biological Control (NBC) -with no application of insecticides throughout the crop growth (b) Schedule based protection (SBP)- application pesticides as per farmers recommendation (C) IPM Treatment- selected component of management at two different villages in the district of Bankura and Birbhum. The pooled data from the corresponding years (2002, 2017 and 2003, 2018) of the seasons indicated that among the three treatments the Integrated Pest Management system which included cultivation of resistant variety viz., Chaityanya (MTU-2067), delaying of planting time up to first week of August, application of fertilizer @ 60:40:40 (N:P:K) with spacing 20x15cm, alternate wetting and drying the field at 80, 87 and 94 DAT, and spraying of Imidachloprid 17.8 SL @ 30 gm a.i. / ha at 75 and 90 DAT could maintain the BPH population below economic threshold level in upland rainfed rice growing areas of West Bengal.
