Detection of Different Bacterial and Fungal Pathogens in Apparently Healthy Strawberry Plants

PM 7/65 (2) Xanthomonas fragariae

“…Symptoms appear under favourable conditions (see section 3.1) as well as after cold storage (Rat, 1993). X. fragariae is widespread in nurseries in many countries and has been responsible for important production losses in Europe (Bosshard & Schwind, 1997; López et al, 1985; Mazzucchi et al, 1973). Analyses of X. fragariae strains isolated at different times in diverse locations around the world indicate some genetic and phenotypic diversity among these strains (Opgenorth et al, 1996; Pooler et al, 1996; Roberts et al, 1996).…”

Xanthomonas fragariae

“…The disease has been reported to cause the loss of 75% of fruit in Wisconsin (US) (Epstein, 1966). It is widespread in nurseries in many countries and has been responsible for important production losses in Europe (Mazzucchi et al ., 1973; López et al ., 1985; Bosshard & Schwind, 1997). X. fragariae is easily transmitted via asymptomatic plants with latent infections and international movement of latently infected plants is blamed for the introduction of X. fragariae from the USA to many other countries (López et al ., 1985).…”
