Implementing the systems approach in rice pest management : India context

Abstract

A basic IPM module for basmati rice as a part of integrated crop management accounting the pest prevalence and management has been developed. As the IPM module is location specific and dynamic, there is need of regular updating and fine tuning depending on the location and pest prevalence. The technology has been successfully validated and implemented during 1998 to 2019 in Pusa Basmati 1, Taraori Basmati, Dehraduni Basmati, Pusa Basmati 1121 in Haryana, Uttar Pradesh and Uttarakhand with minor modification and fine tuning. Adoptation of the IPM technology resulted in increase in rice grain yield to the tune of 21.6% in Pusa Basmati 1 at Shikohpur in Uttar Pradesh, 21.5% in Taraori Basmati at Chhajpur in Haryana, 19.5% in Type 3 in Uttarakhand, 14.5 to 22.7% in Pusa Basmati 1121 in Haryana and 38.2% in Pusa Basmati 1121 in Uttar Pradesh over farmer's practices (FP). In all the basmati rice trials, higher yield as well as Benefit : Cost (B:C) ratio was obtained in IPM as compared to FP. Implementation of IPM led to significant reduction in the uses of chemical pesticides. In case of IPM, on an avarage 1.46 application of chemical pesticides (103.2 g a.i./ha) were undertaken in Pusa Basmati 1121 against 2.8 application in FP (1214.4 g a.i./ha) at Bambawad, Uttar Pradesh. ICAR-NRRI, Cuttack developed and validated IPM module at Sigmapur (Cuttack, Odisha) non-Basmati rice variety Pooja for four kharif seasons i.e 2010-2013 using standard agronomic practices. The trial resulted in an increase of 47.1% yield over FP. Additional income of Rs. 9857/- per ha was also obtained in IPM over FP. On-Farm trial on validation of IPM module in non-Basmati rice (cv. Pooja ) under rainfed low land condition conducted in 10 ha during rabi 2017 at Nagapur and Basudeipur villages in Khurda district of Odisha resulted reduction in the incidence of insect pests and diseases with higher population of natural enemies as compared to FP with B:C ratio of 1.26:1. Rice yield was recorded 5600 kg ha-1 in IPM as against 4900 kg ha-1 in FP. Recently, ICT based e-pest monitoring and advisory has become an important component for area wise implementation of IPM at state and national level. The programme has been successfully implemented in Odisha during 2010 and 2011 under RKVY. Implementation of the programme had resulted successful management of swarming caterpillar in 13 rice growing districts of Odisha during kharif 2010 and 2011. More precisely, the launching of riceXpert app by ICAR-NRRI in the year 2016 has facilitated the farmers for confident identification of insect pests and diseases and getting real-time pest solution instantly
