Push-pull technology has been widely disseminated in developing countries for effective control of stem borers, fall army worm and striga weed, and to improve soil fertility towards the realization of economic, livelihood and environmental benefits of the smallholder farmers that continuously practice it. Despite the extensive literature on PPT adoption, little is known about what drives farmers to keep using or abandon it. This study addresses this knowledge gap by looking at the determinants of PPT dis-adoption in Homa Bay County. A multi-stage sampling procedure was used to select a sample of 240 smallholder farmers. Data were gathered through face-to-face interviews using a pretested semi-structured questionnaire and analyzed using bivariate probit model. The results indicate relatively low PPT dis-adoption rate of 39.94%. Further results show that gender of household head, education level, total land owned, livestock numbers, extension access, and farmer perceptions about desmodium seed availability negatively and significantly influenced the PPT dis-adoption decision. The study concludes that, policy and development interventions should focus on establishment of an integrated seed development system that involves collaboration of all stakeholders in desmodium and napier seed development and distribution at the local level. Such interventions should also focus on ensuring equitable access to quality education, markets, efficient extension delivery system, as well as the strengthening of social ties.
