Field-Based Evaluation of IPM Strategies for Insect-Transmitted Viral Diseases in Rice-Fallow Blackgram in Krishna District, Andhra Pradesh, India | Chapter 02 | Agricultural Sciences: Techniques and Innovations Vol. 6

 

Black gram (Vigna mungo) is an important pulse crop of India. In coastal Andhra Pradesh, it fits well under the rice fallow-pulse ecosystem with residual moisture after the harvest of paddy. However, rice fallow blackgram is mainly attacked by certain pests and diseases leading to great loss to the farmers. In response to these challenges, a potential solution for adoption is Integrated Pest Management (IPM) strategies. This study was conducted in ten locations of the farmers’ fields during 2020-21, 2021-22, and 2022-23 by the KVK and explored the impact of IPM on the Management of Sucking pests in Rice fallow Blackgram with the emphasis on the use of resistant varieties, seed treatment and other cultural practices. Data were recorded from ten randomly selected plants from each field. The observations were recorded to assess the percentage of virus-affected plants. The seed yield, cost of cultivation, net benefit and cost-benefit ratios were also calculated. By adoption of IPM practices in all three years, the incidence of the leaf crinkle, leaf curl and YMV was reduced in comparison with farmers’ practice; while bud necrosis was not noticed in all these years. This has resulted in a reduction in the average cost of cultivation by Rs. 2690.00 per hectare, and the average net income was improved by Rs. 13596 per hectare compared to the farmers' practice. The average yield levels (1659 kg/ha) improved by 10.91 per cent compared to farmers' practice (1496 kg/ha), giving a clear indication that adoption of IPM practices helped in improving the net income levels to the resource-poor farmers. This study concluded that IPM practices are substantially more effective than indiscriminate pesticide use for managing sucking pests like Aphids, Jassids, Thrips and Whiteflies and associated viral diseases in rice fallow blackgram. To minimize early vector infestation and prevent yield losses, integrated approaches involving seed treatment, elimination of alternative weed hosts, and cultivation of resistant varieties should be prioritised.
