Résumé:
Cowpea can be affected by several diseases, among which the v roses
constitute a limiting factor for culture. It is of great importance to
understanding of the ways in which these pathogens are disseminated in the field,
the objectives of this work were to detect the presence of viruses in seeds
of lbijãoaupi by means of biological tests e. check for the presence of plants
weed hosts of viruses. The seeds were collected from fields. of
production with a history of the occurrence of viruses in the municipalities.
Paulista and Lagoa The seeds were sown individually in.
128 cell styrofoam containing sterile commercial substrate and the plants spin
assessed by visual observation of the symptoms in the primary leaves and the
weeds with typical symptoms of mosaic and leaf deformation were
collected in the municipalities of Sousa, Pombal and Paulista, and analyzed.
'enzyme linked immunosorbent assay' (Elisa) indirect against specific antisera
for Cowpea aph / dborno mosalc vlms (CABMV) and Cucumber mosalc wms (CMV) .e
by double diffusion in agar against anta-serum for Cowpea severa mofa / c wn'i / s
