Master Of Science In Plant Pathology

Fees Detail


Agriculture is the main economic activity in Kenya, with horticulture being a major foreign exchange earner and the staple crops are important to food security. However, for the country to attain food security and to fully benefit from international trade opportunities, pre- and post harvest crop losses due to plant diseases must be reduced to minimum levels possible. Increased access to markets creates wealth at all levels, from macro-economic growth to poverty reduction both at individual and family levels. The postgraduate training programme in plant pathology will cover causes of plant diseases, factors that influence plant disease epidemics and their management, including training on pesticide use, efficacy and their effects on the environment. Host-pathogen relationships, plant disease resistance and biotechnology aspects will also be addressed. In addition, the trainees will be taught research methodologies to equip them with tools required in experimental design, data collection, analysis, interpretation andcommunication of research findings. Therefore, the training programme will produce competent personnel capable of handling all issues relating to plant diseases, their management and making enlightened decisions in this field. The revised MSc. Plant Pathology curriculum has introduced flexibility in the mode of delivery and incorporates new topics such as entrepreneurship and phytosanitary regulations in order to address the changing job market requirements. Open and distance learning mode is preferred by employers and the self employed since it allows students to undertake training while still on the job. The revised curriculum is therefore, designed to offer client-friendly training in plant pathology to produce graduates well prepared and equipped for the modern job market. The objectives of the programme are to: 1.1 Train qualified personnel in the field of plant pathology who will be competent in identifying and managing plant diseases using environmentally safe procedures. 1.2 Equip the candidates with the necessary tools to undertake research in all fields of plant pathology. 1.3 Train the candidates on how to collect, analyse, interpretcommunicate and present their research findings in seminars, workshops and scientific publications. 2.0 ADMISSION REQUIREMENTS The common regulations governing Master?s degree in the University of Nairobi and the Faculty of Agriculture shall apply. 2.1 A holder of a degree with at least Upper Second Class Honours in Bachelor of Science in Agriculture, Botany and Zoology, Environmental Sciences, Forestry, Horticulture or related plant science degree or Bachelor of Education in Science with botany and Zoology option and any other relevant subject from the University of Nairobi or any other institution recognized by senate. 2.2 A holder of a degree with at least Lower Second Class Honours in any of the degrees specified in (2.1) above with two years of relevant experience or a postgraduate diploma in (2.1) above or equivalent from the University of Nairobi or any other institution recognized by senate. 2.3 A holder of a pass degree with a postgraduate diploma in the above relevant disciplines or its equivalent from the University of Nairobi or any other institution recognized by the senate. 2.4 A holder of pass degree in any of the degree categories specified in (2.1) above with at least five years relevant work experience. 3.0 TRANSFER OF CREDITS AND EXEMPTIONS 3.1 A candidate may be exempted from taking some course units and be allowed to transfer credits of the same up to a maximum of one third (_) of the taught units provided that these are from institutions recognized by the University of Nairobi Senate. 3.2 A candidate seeking transfer of credit shall send a formal application to the Board of Postgraduate Studies, through the Dean, Faculty of Agriculture, justifying and supporting the request. 3.3 Transfer of credits shall be processed only after payment of the prescribed non-refundable fees. 4.0 COURSE STRUCTURE AND DURATION The programme will be offered as full time, part time and through Open and Distance e-Learning (ODL) for students who cannot attend regular University programmes. 4.1 Full-Time 4.1.1 The degree program shall consist of coursework, examinations and thesis. 4.1.2 The course shall cover a minimum of 4 and a maximum of 8 semesters and each semester shall be of 15 weeks duration. 4.1.3 Each candidate will be required to take and pass all courses. 4.1.4 Each candidate will be required to undertake a research project leading to an examinable thesis.
