cv. Bleek from Coquimbito (Mendoza, Argentina)
presented a marked delay of the growth
and tardiness on inflorescences formation.
Healthy crops had 1 m of height while ill
ones did not reach 30 cm. The most external
leaves showed chlorosis and light wilt with
subsequent necrosis. It was made isolations
in PGA, where colonies of mucous
aspect, over elevated of light brown colour
were developed. It was isolated, too in base
Kelman media without TZ where colonies
of the same above characteristics were
developed but they presented festooned
borders typical of the Erwinia genus. It was
made biochemical and pathological tests
en greenhouse resulting positives. Erwinia
