柔软短杆菌致病变种菜豆细菌性萎蔫病的病原菌是菜豆（Phaseolus spp.）并且是全身性细菌。该病于20世纪20年代首次在美国（南达科他州）的菜豆上发现，随后在澳大利亚、加拿大、墨西哥、南美洲和突尼斯均有记录。它在罗马尼亚和俄罗斯有限制的分布。虽然在比利时、保加利亚、希腊、匈牙利、波兰、土耳其和乌克兰都有记录，但它尚未建立，现在被认为不在这些国家。最近在西班牙东南部的几个油田有报道（Gonza 'lez等人，2005年）。除此之外，C.软腐病致病变种在EPPO区域中的florescenaciens。没有有效的化学方法来对付这种疾病，如C。软腐病致病变种florifaciens是一种种子传播的细菌，目前的控制方法主要是基于使用健康认证的种子。在经济上，C.软腐病致病变种florescence faciens是P. vulgaris L.，但该细菌也攻击红假单胞菌，月蕨和蒙戈木（P. mungo L.）自然感染C。软腐病致病变种已在豇豆属（Vigna spp.）[V. angularis（Willd.）Ohiwi & Oashi，辐射V. radiata（L.）R.威尔茨和V. unguiculata（L.）Walsp. spp. unguiculata]、大豆（Glycine max（L.）Merr.和豌豆（Pisum sativum L.）有关C的更多一般信息。软腐病致病变种flavonifaciens，参见EPPO/CABI（1997）。这一诊断程序对C.软腐病致病变种flavonifaciens描述了从植物材料或种子中提取，用快速测试和同时分离细菌菌落的推定诊断，C.软腐病致病变种产flocculofaciens推定的分离株，并在相关的情况下，确定致病性。给出了描述该过程的流程图。
Curtobacterium flaccumfaciens pv. flaccumfaciens is the causal agent of the bacterial wilt disease of Phaseolus spp. and is a systemic bacterium. The disease was first discovered in the United States (South Dakota) in the 1920s on Phaseolus vulgaris and subsequently recorded in Australia, Canada, Mexico, South America and Tunisia. It has a restricted distribution inRomania andRussia. Although it has been recorded in Belgium, Bulgaria, Greece, Hungary, Poland, Turkey and Ukraine, it has not established and is now considered absent from these countries. It has recently been reported in few fields in South-Eastern Spain (Gonza´lez et al., 2005). Apart from this record, there are few recent records of C. flaccumfaciens pv. flaccumfaciens in the EPPO region. No effective chemical methods are known against this disease; as C. flaccumfaciens pv. flaccumfaciens is a seed-borne bacterium, current control methods are based mainly on the use of healthy certified seeds. Economically, the most important host of C. flaccumfaciens pv. flaccumfaciens is P. vulgaris L., but the bacterium also attacks P. coccineus L., P. lunatus L. and P. mungo L.. Natural infections by C. flaccumfaciens pv. flaccumfaciens have been observed on Vigna spp. [V. angularis (Willd.) Ohiwi & Oashi, V. radiata (L.) R. Wilcz. and V. unguiculata (L.) Walsp. spp. unguiculata], on Glycine max (L.) Merr. and on Pisum sativum L. For more general information about C. flaccumfaciens pv. flaccumfaciens, see EPPO⁄CABI (1997). This diagnostic procedure for C. flaccumfaciens pv. flaccumfaciens describes extraction from plant material or seeds, presumptive diagnosis with rapid tests and simultaneous isolation of bacterial colonies, identification of C. flaccumfaciens pv. flaccumfaciens putative isolates and, where relevant, determination of pathogenicity. A flow diagram describing the procedure is given.
