Biological control of Sclerotinia sclerotiorum by the mycoparasite Coniothyrium minitans

Coniothyrium minitans is a fungal parasite of sclerotia (resting bodies) of the internationally important plant pathogen, Sclerotinia sclerotiorum. At Warwick HRI we have investigated a range of features of the mycoparasite associated with its successful use as a biological control agent. These include its intraspecific diversity, examination of spore and germling surface features, studies on ecology and environmental impact, inoculum production and application, and its integration with reduced applications of fungicides.

Recently, we have been examining key features involved in pathogenicity of C. minitans through use of gene knockouts and by examining changes in gene expression during sclerotial infection. In addition, we are studying the role of antifungal metabolites produced by C. minitans in the infection process.
