Root-knot nematodes in tomatoes cause financial loss to Kenyan smallholders. While soil fumigation appears to be losing effectiveness two bio-control agents (bcas), Pasteuria penetrans and Verticillium chlamydosporium, appear promising. Participatory budgeting is being used to compare the bcas with chemical and other biological controls on commercial and organic smallholdings. %K Colloquium of Organic Researchers; COR; tomato; root-knot nematode; participatory budgeting; Kenya; biological pest control %P 123-124 %E Jane Powell %E et al. %D 2002 %I Organic Centre Wales, Institute of Rural Studies, University of Wales Aberystwyth %L orgprints8311
