Nematologists at Rothamsted have had an association over the past 12 years with colleagues in CENSA, who have been involved in nematode taxonomy and the development of a selected isolate of Pochonia chlamydosporia var. catenulata as a biological control agent for root-knot nematodes in tropical soils. Methods for the production of the fungus suitable for small-scale growers have been optimised and a product, KlamicŪ, has been produced to EPA standards for commercial use in Cuba.
This project is co-ordinated by Dr Zibusiso Sibanda in Zimbabwe and Brian Kerry (NIU) and brings together nematologists in Kenya, Malawi, Tanzania and Uganda and UK partners in the University of Reading (Dr Simon Gowen) and CABI BioSciences (Dr David Hunt). It has equipped six laboratories in the region, established an interactive website (http://www.africannematology.info/aboutus.asp) that provides access to major nematology journals to members of NIESA and is involved in collaborative research, raising awareness of nematode problems and training.

In the past three years more than 60 people involved in nematological research, plant health, teaching and technical advice have been trained in plant nematology by members of NIESA, on courses ranging from 2 days to 6 weeks duration. Members of the group received additional funding from the Royal Society, to extend networks in Tanzania and South Africa and from the BBSRC/DFID SARID Initiative for research on the nutrition of Pochonia chlamydosporia and its biocontrol efficacy; a collaboration between Rothamsted Research and the University of Nairobi. Currently, three PhD students are being trained within the Group.
This British Council funded link supports scientific exchanges between the NIU at Rothamsted and members of the nematology department in the Indian Agricultural Research Institute (IARI), New Delhi. This project is coordinated by Dr Keith Davies at Rothamsted and by Professor Harish Gaur at IARI. The overall aim of the collaboration is to improve understanding of the mutitrophic interactions in the rhizosphere in order to increase root health and the resource use efficiency of crops grown in nematode-infested land. Currently, research exchanges involve both PhD and postdoctoral scientists studying the impacts of nematodes on plant nutrition, nematode attraction to plant roots and the genomics of Pasteuria penetrans.
Members of the NIU have enjoyed a long and productive association with nematology colleagues in the Departamento de Zoologia, currently led by Prof. I.M.O. Abrantes. Collaborative research involves both PhD and postdoc .scientists and targets the biological control of potato cyst nematodes and the diagnostics of Bursaphelenchus xylophilus.
