Abstract
Root-knot nematode (Meloidogyne spp.)is a serious pest problem in smallholder tomato farms in Kenya. Awareness of the toxicity effects and increasing costs of chemical control for root-knot nematodes has led to demand for alternative nemede management strategies, including the use of potential biological control agenet. The use of Veticillium chlamydosporium and pasteuria penetrans, as biocontrol agenets (BCAS) in tomato nursey beds has been evaluated and the results are presented in this paper. The biocontrol agents significantly lowered the number of nematodes in roots of tomato seedlings, four weeks after seeding. Alternative treatment: Crotalaria, Dazomet 98% (Basa Granular)and trash burning, significantly reduced the number of second stage juveniles in soil. Transplanting seedlings, from the BCA treatment, to a nematode infested field reduced the number of egg masses at the end of the harvisting period but did not result in a significant increase increase in tomato yield.
