Common bean (
Phaseolus vulgaris
L.) is the most important legume
crop in Kenya and is cultivated on an estimated 700,000 ha. A low
average yield of 750 kg/ha is realized, against a potential of 1500 kg/
ha (Rheenen
et al.,
1981). The major constraints to bean production
are diseases, soil fertility, insect pest and low erratic rainfall (Otsyula
et al.,
1998). Common bean is plagued by a wide range of plant parasitic
nematodes, but only
Meloidogyne
spp. are of economic importance,
causing up to 60% losses in yield (Ngundo and Taylor, 1974, Kimenju
et al.,
1999). Apart from the direct losses resulting from root
deformation, nematode infection is also known to break host resistance
to other pathogens and to suppress nodulation. Several strategies have
been developed for the control of root-knot nematode but their adoption
level by smallhold farmers is limited (Table 1).
This study was undertaken with ultimate aim of developing an integrated
strategy of managing root-knot nematodes on beans
