Prosopis juliflora is an invasive woody plant that was introduced to Marigat Sub County of Baringo County in 1970s and over the years its spread has altered the livelihoods of the pastoral communities who are the majority in most of the affected areas. This is because  Prosopis juliflora invasion has reduced available dry season grazing fields, chocked river banks and interfered with access roads.  To control its spread several management and control technologies were promoted in Marigat Sub-County in early 2004 that included clearing and planting pasture, charcoal production and killing of cut stumps with chemicals among others. However, the interventions have not yielded the desired results for the species has continued to spread into newer areas and intensifying their presence in already invaded areas. A study was initiated in 2017 to determine the factors influenced the local households to adopt the promoted management and control technologies in Marigat Sub-county one of the areas of original introduction and most affected by the infestations. The study was done through socio-ecological survey using questionnaires and checklist administered to 337 households. The factors considered were Socio-economic (education, land size income) and demographic (gender, age, household size). Data collected was then processed and analyzed using descriptive and inferential statistics of SPSS. The inferential tools used were chi-square analysis, regression and correlation analysis and Pearson Moment Correlation analysis. The results showed land size, incomes from Prosopis products, age and household size significantly influenced adoption of management and control technologies for Prosopis in the study area. The adoption rates association direction depended mostly on labour availability and incomes to hire extra labour for undertake the arduous job of Prosopis clearing and control of reinvasions. Level of education of the respondents had no significant effect on the adoption rates of the various control measures.
