Chemoattractant for Ralstonia solanacearum was searched in the root exudate of tomato. The root exudate of tomato was fractionated into EtOAc-soluble fr. and absorbed and non-absorbed (passed) fr. of activated charcoal column, and their chemoattractive activity was examined. Passed fr. of activated charcoal column showed strongest activity and absorbed fr. was less active. Comparison of chemoattractive activity between passed fr. and amino acid mixture equivalent to the fr. showed the presence of chemoattractant other than amino acids.Fractionated root exudates of non-host plant of R. solanacearum, i.e. rice, rape and alfalfa were prepared and their chemoattractive activity was examined. As a result, passed fr. of activated charcoal column of tomato showed stronger activity than those of other plants.

在番茄的根部渗出液中搜索了用于拉尔斯托尼亚溶剂的化学吸引剂。将番茄的根部渗出液分馏为Etoac溶解的FR。并吸收并非吸收（通过）fr。活性木炭柱及其趋化活性。通过了。活性炭柱的活性最强和吸收的FR。不太活跃。通过FR之间的趋化活性比较。和氨基酸混合物等效于FR。在制备了非氨基酸以外的趋化剂。结果，通过了fr。番茄活性炭柱的活性比其他植物的活性更强。
