Bacterial wilt of strawberry caused by Pseudomonas solanacearum has been observed in nurseries in some areas of Shizuoka Prefecture, killing around 30 percent seedlings at most every year. The symptoms found on the cultivar HOKO WASE under the natural conditions were the acute wilting of the younger leaves, resulting soon in total death of the plants. The cultures isolated from the diseased plants were identified as the pathovar 8a (biovar III) and 4 (biovar IV). In the inoculation tests, however, the disease development was rather mild and slow regardless of the inoculation techniques such as the prick method or the immersion method in which the root systems or the cut-end of runners were dipped into the bacterial suspensions for 10min. The pathogen could survive in the tissues of some inoculated plants until next spring. The reisolation trials made 8 to 10 months after inoculation revealed that the rates of the carrier plants were about 10% in the cultivar FUKUBA and 5% in HOKO WASE. In most cases, these plants grew as vigorous as the non-inoculated healthy plants and set fruits normally. In the diseased plants, either under the natural conditions or artificially inoculated, plugging by bacterial cells was usually restricted to only a small number of tracheary elements in a xylem tissue, where the cell walls were often broken down forming bacterial pockets. It was remarkable that the bacterial fissures were often observed in the parenchymatous tissues of the infected stems even when the invasion of the vascular tissues was slight.
