Sericulture in Karnataka is in the process of modernization in many phases through new demand driven extension approach called Technical Service Centres (TSCs) located at the grass-root level (Hobli and Taluka level). These centres are mainly involved in the dissemination of the technologies developed by the Research Institutes and also in supply of mulberry cuttings/saplings, monitoring mulberry cultivation, silkworm rearing and providing information about loan facilities and subsidy schemes. There is a need to study the attitude of sericulture beneficiary farmers towards activities of TSCs. The study was conducted during 2018-20 in the Karnataka state which contribute 35 per cent of silk production in India. An ex-post facto research design was used or the study. Knowledge test was constructed to measure the knowledge of sericulture farmers on recommended sericulture technologies. The Ramanagara and Mandya districts were selected because these district have highest number of TSCs in Bangalore and Mysore division respectively. Mandya, Malavalli and K.R Pet taluks from Mandya district as well as Ramanagara, Channapatna and Kanakapura taluks from Ramanagara district were selected for the study with four TSCs from each taluk. Totally, 24 TSCs were selected for the study. Ten sericulture farmers under each TSC, collectively 240, were selected by using random sampling method. The study highlighted that more than half (52.50%) and more than one third (36.25%) of the sericulture farmers had medium and high knowledge on recommended technologies of sericulture respectively. Only just more than one tenth (11.25%) of the sericulture farmers had low knowledge on recommended technologies of sericulture. The probable reason might be due to fact that sericulture farmers were regularly consulting from officials of grainage centres, TSC extension functionaries, input dealers and peer group about the information on latest sericulture technologies.
