Title (EN) ANTIFUNGAL MICROORGANISM
(FR) MICRO-ORGANISME ANTIFONGIQUE
Abstract:
(EN) A method for the screening of potential antifungal agents comprises testing the inhibitory effect of the potential antifungal agent in two tests, a first test for inhibition of pathogen development in sterilised soil infested with mycelium of $i(Pythium) spp and a second test against for inhibition of disease development in a growing plant of a species susceptible to disease from damping-off disease complex in the presence of the said complex, identifying agents giving potential inhibitory effect in both tests compared with control and submitting same for further examination. Using this method four particularly useful microorganisms which display antifungal activity in a wide spectrum, shown in further testing and in field trials, of disease fungi have been provided. Methods of using such microorganisms and compositions containing same are also described.
(FR) Méthode de sélection d'agents potentiellement antifongiques dont on teste l'effet inhibiteur en deux étapes. Le premier test consiste à inhiber la propagation de pathogènes dans un sol stérilisé infesté de mycélium de $i(Pythium) spp. Le deuxième consiste à inhiber l'extension de la maladie chez un végétal en pleine croissance appartenant à une espèce susceptible de la contracter à partir d'un complexe d'amortissement pathogène en présence dudit complexe. On identifie ensuite les agents qui produisent au cours des deux tests un effet potentiellement inhibiteur par comparaison avec le témoin, puis on les étudie plus en détail. Cette méthode a permis d'identifier quatre micro-organismes particulièrement utiles qui déploient une activité antifongique à large polyvalence, ainsi que l'ont montré les tests ultérieurs et les essais de plein champ. La présente invention décrit aussi les méthodes d'utilisation de ces micro-organismes et des compositions qui les contiennent.
