Importance of crop residues for the survival of plant pathogenic fungi

Many plant pathogenic fungi depend on crop residues for their survival from one crop to the next.

Pathogen inoculum on straw left in the field gives higher risk for disease at conditions favorable for disease development, but the knowledge about factors influencing pathogen survival on straw is scarce. We investigate the persistence of Fusarium graminearum and Oculimacula yallundae, on decaying straw under varying conditions, and how the inoculum density is related to the ability of the pathogens to cause disease.
