Serbia originate from imported seeds and planting material.
Despite the fact that active quarantine measures
are regularly employed, a small part of the imported
planting material and potted plants of Impatiens have
been proved to be infected with TSWV (Krstić et al.,
2005a, 2005b). During a survey for TSWV on ornamentals
in greenhouse production in Serbia (Krstić et
al., 2006) growers have been observed to produce their
own Impatiens planting material sometimes by using
diseased mother plants. For that reason an investigation
was conducted in Serbia to establish a successful
protocol for virus elimination from TSWV infected
Impatiens plants.
