Experiments were carried out at ten locations of surrounding area of Krishi Vigyan Kendra, Manjhi, Saran district, Bihar during kharif season 2014 and 2015 with brinjal crop cv ‘Pant Rituraj’. The assessment reveled that module (M4) proved the most effective treatment against brinjal pest and diseses i.e. brinjal shoot and fruit borer, little leaf of brinjal, white fly and red spider mites, Tetranychus cinnabarinus (Boisd) in which lowest incidence was recorded as compared to other IPM modules, farmer practices and control plot during 2014 and 2015. Module (M3) was next effective treatment against the major pest of brinjal crop in both years. Significantly, maximum fruit yield was observed in module (M4) 214.03 and 210.10 q/ha during 2014 and 2015, respectively. This was significantly superior over all other treatments. The impact of various IPM modules showed that mean net return was also higher in module (M4) which was Rs 91897.00/ha. Application of neonicotioids or chloronicotinyl insecticides in module (M4) along with other IPM strategies gave effective management from shoot and fruit borer, little leaf of brinjal and red spider mites and received higher yield as compared to other insecticides like quinalphos and fenvalerate.
