Biological control of crown rot of bananas with Pichia anomala strain K and Candida oleophila strain O

Lassois L., De Lapeyre de Bellaire L., Jijakli M.H.. 2008. Biological Control, 45 (3) : p. 410-418.

The antagonistic activity of two yeast strains (Pichia anomala (E.C. Hansen) Kurtzman, strain K and Candida oleophila Montrocher, strain O) against the parasitic complex responsible for banana crown rot was evaluated. The strains were applied at three different concentrations (106, 107, 108 cfu/ml) and their efficacy tested in vivo on three separate fungi (Colletotrichum musae (Berk. & Curt.) Arx, Fusarium moniliforme Sheldon, and Cephalosporium sp.) and on a parasitic complex formed by association of these three fungi. At the concentrations used C. musae appeared to be the most pathogenic. The complex showed intermediate aggressiveness between C. musae and both other fungi. (Résumé d'auteur)
