Abstract:
Green manure plants were evaluated to determine their
suitability as rotation crops with common bean to suppress root-knot (Meloidogyne
spp.) nematodes. They were also evaluated as soil amendments in nematode
control. The plants were Calliandra calothyrsus, Canavalia ensiformis,
Chenopodium quinoa, Crotalaria juncea, Desmodium uncinatum,
Gliricidia sepium, Leucaena leucocephala, Mucuna pruriens,
Tephrosia purpurea, Tithonia diversifolia, Vicia villosa,
Sesbania sesban and Tagetes minuta. In the glasshouse, pots
were filled with steam-sterilized soil and sown with green manure plants.
The rotation experiment entailed growing green manure plants for three
months before uprooting them and planting beans in the same pots. The
potting medium was infested with 6000 eggs/juveniles of Meloidogyne
javanica. The field experiments were carried out in microplots infested
with a mixture of M. javanica and M. incognita. Damage to
bean roots due to root-knot nematodes was based on galling indices while
nematode reproductive potential was based on egg mass index. Tithonia
diversifolia, D. uncinatum, T. minuta, L. leucocephala
and C. juncea were among the most effective in root-knot nematode
suppression when used in rotation with beans. Their galling indices ranged
between 1.0 and 1.5 under field conditions and were thus considered resistant.
Vicia vilosa, T. purpurea and S. sesban were susceptible
with galling indices ranging between 6.2 and 7.7. The resistant plants
reduced the reproductive potential of Meloidogyne spp. by up to
80% while the susceptible plants caused an increase of up to 600%. Therefore,
T. diversifolia, D. uncinartum, T. minuta, L.
leucocephala and C. juncea can be recommended for use in fields
infested with root-knot nematodes.
