Evaluation of Integrated Pest Management Against Yellow Mosaic Virus Disease in Blackgram

The evaluation of integrated pest management (IPM) against viral diseases in blackgram was conducted by District Agricultural Advisory and Transfer of Technology Centre (DAATTC), Vizianagaram in five farmer’s field during rabi seasons of 2019-20 and 2020-21. The results revealed that the disease incidence was lower in IPM module (11.92 %) compared to farmers’ practice (27.09 %). An increase in yield of 32.44 % was observed in IPM demonstration (813 kg/ha) compared to farmers’ practice (614 kg/ha). The net returns were Rs. 26,339.00 for the IPM module and Rs. 15,810.00 for farmer’s practice. The extension gap, technology gap, and technology index were 199 kg/ha, 213 kg/ha, and 20.73 %, respectively. The lower technology index indicates that the technology is feasible for farmers’ fields and needs to be popularized to reduce the extension gap and technology gap.
