“…In addition to Pseudomonas spp., the causal agents of soft rot in witloof chicory (Cichorium intybus) have been identified as both Pectobacterium and Dickeya spp. (Bouvard 1987;Vantomme et al 1989;Le Guern et al 1992;Samson et al 2005; see Table 3.1).…”

“…The more critical phase for soft rot development is during head forcing, which has become a more significant problem since the introduction of hydroponic systems for this stage of the process, which uses circulating nutrient solutions. In these systems, losses of 50% or more total production regularly occur when susceptible cultivars were used (Vantomme et al 1989;Le Guern et al 1992).…”

“…In Europe bacterial isolates belonging to Erwinia sp. include dangerous phytopathogenic bacteria on witloof chicory crops (Marchal, 1933;Samson et al, 1980;Bouvard, 1987;Jansen and van Kruistum, 1992;Anon, 1989: Vantomme et ai., 1985, 1989Gallois et al, 1992;Le Guern et al, 1992;Di Lenna et al, 1994).…”

“…Witloof chicory is susceptible to phytopathogenic bacterial populations and attacks in three different phases of its production: roots grown in the open field, storage, and forcing of the white head from mature roots under controlled temperature conditions (17 C) and darkness (Le Guern, 1992), Slime rot is frequently seen in hydroponic culture, in 'forcing room' using circulated nutrient solutions and where environmental conditions (extremely humid conditions) are favourable to the explosion of the bacterial diseases. Brown rot has been observed not only during the forcing stage but also in root production in the field (Vantomme et al, 1989).…”

Distribution of principal phytopathogenic bacterial populations on witloof chicory crops in Europe is reported. Different symptoms caused by phytopathogenic bacterial populations on different parts of witloof chicory plants are described. The first report of Pseudomonas fluorescens (Trevisanj Migula and occurrence of Erwinia carotovora (Jones, 1901) bacterial populations on witloof chicory cv. Rosso di Chioggia crops in Italy (Latium region), are reported. Risks of disease during different phases of production of this crop and phytosanitary measures to reduce the incidence of disease caused by these pathogens are discussed. Zusaramenfassung Bakterienkrankheiten von Chicoree in Europa Uber das Vorkommen der wichtigsten Bakterienkrankheiten des Chicoree in Europa wird berichtet. Die von phytopathogenen Bakterien auf verschiedenen Pflanzenteilen des Chicoree hervorgerufenen Symptome werden beschrieben. Erstmals wird uber einen Befall der Chicoreesorte Rosso di Chioggia in Italien (Region Latium) durch Pseudomonas fluorescens (Trevisan) Migulas bedchtet. Auch Erwinia carotovora (Jones 1901) kam auf diesen Pflanzen vor. Das Krankheitsrisiko wahrend verschiedener Wachstumsstadien des Chicoree wird besprochen, und phytosahitare Mafinahmen zur Verringerung der Inzidenz der durch die genannten Pathogene hervorgerufenen Krankheiten werden diskutiert.

Pectobacterium and Dickeya spp. are related broad-host-range entero-bacterial pathogens of angiosperms. A review of the literature shows that these genera each cause disease in species from at least 35% of angiosperm plant orders. The known host ranges of these pathogens partially overlap and, together, these two genera are pathogens of species from 50% of angiosperm plant orders. Notably, there are no reported hosts for either genus in the eudicots clade and no reported Dickeya hosts in the magnoliids or eurosids II clades, although Pectobacterium spp. are pathogens of at least one plant species in the magnoliids and at least one in each of the three eurosids II plant orders. In addition, Dickeya but not Pectobacterium spp. have been reported on a host in the rosids clade and, unlike Pectobacterium spp., have been reported on many Poales species. Natural disease among nonangiosperms has not been reported for either genus. Phylogenetic analyses of sequences concatenated from regions of seven housekeeping genes (acnA, gapA, icdA, mdh, mtlD, pgi, and proA) from representatives of these genera demonstrated that Dickeya spp. and the related tree pathogens, the genus Brenneria, are more diverse than Pectobacterium spp. and that the Pectobacterium strains can be divided into at least five distinct clades, three of which contain strains from multiple host plants.
