| Sumario: | Ralstonia solanacearum (Rs) causes
the disease quarantine called bacterial wilt
in potatoes. Mexico importseed from United
States of America (USA) and Canada, which is
a significant aspect to eventual introduction of
the disease in areas with large tracts of potato.
Sonora is an important region in relation to
potato production. Therefore, this research
was conducted, with the following objectives:
a) production of antibody for Rs; b) diagnosis
of Rs in foreign tuber, and in tuber for human
consumption which is used for seed; c) detection
of Rs in vegetative growth of potato lots in
Sonora, Mexico. We analyzed seed, seedling,
leaf and tuber; the detection methods used were:
specific means, ELISA, antiserum produced
and pathogenicity tests. The positive results
have shown the presence of Rs in tubers for
consumption; in foreign tuber and vegetative
stages it was negative. The separate testing
should not be used as a unique method of
detection; the presence of Rs, represents a risk
of eventual manifestation of the disease, so it is
necessary to undertake activities with preventive
phytosanitary control. |
