Abstract

Push-pull technology (PPT) is currently and widely promoted as a control measure for stemborers, Striga weed and soil fertility improvement in maize fields in western Kenya in order to improve on cereal production. Since it is a new and relatively knowledge-intensive technology, access information about its efficacy is critical for maximum adoption and continued use. Given that different technologies may need different pathways for adoption, this study sought to identify the most effective dissemination pathway(s) for scaling up the technology among many farmers. A two limit Tobit regression was used to analyze data from 491 respondents randomly selected from four districts in western Kenya. The results indicated that chronologically field days (FD), farmer field schools (FFS) and farmer teachers (FT), had the greatest impact on the probability that a farmer in the study area would adopt PPT and at enhanced intensity of adoption. Efforts to disseminate PPT should therefore target the use of demonstrations through field days to intensify adoption. FT and FFS where appropriate can be used as alternative pathways to reinforce extension messages.
