Abstract: The present study reports the possible use of the Banana bunch rachis(BBR, a residue generally lost or neglected in Guadeloupe and Martinique) as an organic amendment of the soil to control the stem blight fungus Sclerotium rolfsii. The soil amended with the residue at the dose of 4%(w:w) was suppressive to the fungus. In fact, the active part of the BBR was in the juice which was still effective after heating (boiling or autoclaving). The BBR juice decreased the soil infectious potential due to S. rolfsii and affected the growth of the fungus in laboratory experiments. In the field, it also reduced the population of viable S. rolfsii sclerotia. Non-toxic and toxic fractions ( operating in different soil types) were extracted from the juice.
