Lutte biologique contre Botrytis cinerea, agent de la pourriture grise de la vigne

Grey mould disease caused by Botrytis cinerea is one of the most important diseases of the grapevine. The intensive use of the chemical products to irradicate the grey mould disease resulted in environmental pollution, and appearence of the resistant varieties of the pathogen. This study of research showed the antagonism between the B.cinerea and the bacteria and yeast, and the different isolates of the genus Pythium. The selected antagonistic microbes to Botrytis cinerea, were identified using morphological as well as genetical tools and the study of their mode of action was initiated. The enzymatic activities and the elicitation capability were also studied. These activities have a direct relationship with the trigerring of the natural defence mechanisms of the grapevine. In the following context, the use of the selected micorobes as biocontrol agents can be undertaken for the effective control of Botrytis cinerea.
