Caract\u00e9ristiques g\u00e9n\u00e9rales et mode d’action<\/h3>\n

Nous avons commenc\u00e9 \u00e0 travailler avec Pseudomonas fluorescens<\/em> en 2011, une bact\u00e9rie d\u00e9j\u00e0 largement d\u00e9crite comme co-assistante \u00e0 la mycorhisation, mais dont le principal probl\u00e8me en termes de commercialisation \u00e9tait le fait qu’elle perd rapidement sa viabilit\u00e9 \u00e0 temp\u00e9rature ambiante, surtout lorsqu’elle est formul\u00e9e en liquide. Notre \u00e9quipe a d\u00e9velopp\u00e9 une souche de poudre lyophilis\u00e9e qui maintient sa viabilit\u00e9 pendant 12 mois.
\nDans les \u00e9tudes que nous avons r\u00e9alis\u00e9es, en quantifiant le myc\u00e9lium de la truffe avec de l’ADN, nous avons observ\u00e9 comment, apr\u00e8s l’application de cette bact\u00e9rie, la concentration de myc\u00e9lium de la truffe cro\u00eet de fa\u00e7on exponentielle<\/strong> dans la p\u00e9pini\u00e8re et surtout dans les jeunes plantations de ch\u00eanes, avec une corr\u00e9lation directe dans l’entr\u00e9e en production de ces arbres sur le terrain<\/strong><\/p>\n

Format et mode d’application<\/h3>\n

Conteneur de 1kg\u00a0en poudre soluble dans l\u2019eau, \u00e0 la concentration de 2×108<\/sup> CFU\/g. Son application est recommand\u00e9e sur les truffiers \u00e0 tout stade de culture. Il est recommand\u00e9 de r\u00e9p\u00e9ter son application 2 \u00e0 4 fois pendant la phase v\u00e9g\u00e9tative de l’arbre de mars \u00e0 octobre.
\nLes doses d’application sont :<\/p>\n

    \n
  • Arbres de 1 \u00e0 3 ans 0,2 g\/arbre<\/li>\n
  • Arbres 4-9 ans 0,5 g\/arbre<\/li>\n
  • Arbres >10 ans 1 g\/arbre<\/li>\n
  • Puits au truffe : 0,5 g\/arbre<\/li>\n<\/ul>\n
