番茄细菌性疮痂病又称斑点病,对番茄生产影响很大。该病主要危害番茄叶片及果实,近地面老叶先发病,逐渐向上部叶片发展,如条件适合,长期高温高湿时,短期内田间植株叶片呈焦枯状。疮痂病原细菌可随病株残体在地表或粘附在种子表面越冬,成为翌年初侵来源,在田间主要随大风大雨传播,也可由昆虫传播。病源细菌一般由伤口或气孔侵入叶片。环境条件适宜,浸染叶片后3～6天即可发病,侵染果实5～6天即可发病,田间只要有10％的植株发病,其产生的菌量足够使整块田发病。病菌发育 Tomato bacterial scab also known as spot disease, a great impact on tomato production. The disease is the main hazard to tomato leaves and fruits, the first onset of the ground near the surface of the old leaves, and gradually to the development of the upper leaves, such as the conditions suitable for long-term high temperature and humidity, the short-term plant leaves were coke-like. Scab pathogenic bacteria with the diseased plant debris in the surface or adhere to the surface of the winter, became the source of the initial invasion the following year, the main spread in the field with heavy rain, but also by insects. Pathogenic bacteria commonly invade the leaves by wounds or stomata. Environmental conditions appropriate, 3 to 6 days after the dip leaf can be infected, the infection of the fruit 5 to 6 days to the incidence of field as long as the incidence of 10% of the plants, the bacteria produced enough to make the entire field disease.
