番茄溃疡病(Clavibacter michiganen subsp. michiganense)是一种危险性的细菌病害。自1909年在美国首次报道以来,已广泛地分布于美国各个番茄种植区。我国据俞大绂和方中达1956年报道,1954年在大连市场上看到2个番茄果实症状颇似溃疡病,但分离培养未能证实。刘泮华和张乐于1981年在北京郊区首次发现此病以后,山西、内蒙古、辽宁、黑龙江也相继报道发现此病,且发病率高。为害严重。因此,新疆也将该病列为植检对象。 1991年7月,在新疆玛纳斯县加工番茄上发现有很像溃疡病的症状,但面积小,为害轻,未引起重视。1993年6月,在玛纳斯县、石河子地区相继发现。其中兰州湾乡少数地块发病株率已达56.4%,病果率高达90%。在田间多在座果期发病,首先是下部口十片凋萎下垂,叶片卷缩,顶部枝叶仍正常;有些情况下,植株一侧或
Clavibacter michiganen subsp. Michiganense is a dangerous bacterial disease. Since its first report in the United States in 1909, it has been widely distributed in various tomato growing areas in the United States. According to Yu Dafang and Fang Zhongda in 1956, China reported that in 1954 two tomato fruit symptoms were seen as similar to ulcer disease in the Dalian market, but isolation and culture failed to be confirmed. After Liu Panhua and Zhang Le discovered the disease for the first time in the suburbs of Beijing in 1981, Shanxi, Inner Mongolia, Liaoning and Heilongjiang also reported the disease one after another and reported a high incidence. Seriously harmful. Therefore, Xinjiang will also be the disease as a phytosanitary object. July 1991, found in Manasi County, Xinjiang processing tomato like ulcer disease symptoms, but the area is small, light damage, did not pay attention. June 1993, in Manas County, Shihezi area have been found. Lanzhou Bay Township which a few plots of the incidence of disease has reached 56.4%, disease rate as high as 90%. Occurred in the field during the fruit period, the first is the lower ten mouth wilting drooping, leaf curling, the top branches and leaves are still normal; in some cases, the plant side or
