Abstract
PESTANA, Margarida; GOUVEIA, Manuela and ABRANTES, Isabel. Effects of Solanum sisymbriifolium e S. nigrum on the rootlesion nematode, Pratylenchus goodeyi, parasite of banana. Rev. de Ciências Agrárias [online]. 2009, vol.32, n.2, pp.173-181. ISSN 0871-018X.
The main goal of the present research was to help to devise a more sustainable banana production system by developing a control strategy for the root-lesion nematode, Pratylenchus goodeyi using Solanum sisymbriifolium Lam. and S. nigrum L. as green manure or biofumigants. Initially, a pathogenicity assay was performed and it has been demonstrated that, although P. goodeyi did reproduce on both plants, the reproduction factors (0.001) were sufficiently low to designate these plants as resistant or poor hosts. The addition of both Solanum species influenced banana plant growth. The reproduction of P. goodeyi was greatest on banana plants to which no Solanum species plant parts were added. S. sisymbriifolium water extracts were the most effective on P. goodeyi, mainly at the higher concentration (250 mg/ml). From the results obtained, S. sisymbriifolium and S. nigrum could be used as green manure and as biofumigants.
