PROBLEM TO BE SOLVED: To provide a new microorganism which controls the growth of more kinds of plant-pathogenic microbes than those by conventional microorganisms and exhibits excellent control effects against plant diseases, has a degradation ability for widely degrading many kinds of replant-obstructing substances, and has also an excellent control action against replant failures: to provide a plant disease-controlling agent: and to provide a plant disease-controlling method which each uses the new microorganism, is high in safety, and little pollutes environments.SOLUTION: There are provided the Burkholderia bacterium which controls plant diseases and degrades replant-obstructing substances and the Burkholderia bacterium, in which the base sequence of 16S liposome DNA (16S rDNA) is a base sequence represented by sequence No. 1, and which exhibits a &beta-galactosidase activity.COPYRIGHT: (C)2010,JPO&INPIT【課題】従来に比べてより多くの種類の植物病原菌の生育を抑制し植物病害に対して優れた防除効果を発揮し、かつ多種類の連作障害物質を幅広く分解する分解能を有し連作障害に対しても優れた防除作用を併せ持つ新規微生物を提供することであり、さらにその新規微生物を利用することにより、安全性が高く環境汚染の少ない植物病害防除剤および防除方法を提供する。【解決手段】植物病害を防除し且つ連作障害物質を分解するバークホルデリア属細菌を得た。【選択図】なし
