Abstract

Black spot, the most devastating disease in field pea, is caused by a complex of pathogens including Didymella pinodes, Phoma pinodella, Ascochyta pisi, and some other fungirecently found to be associated such as Phoma koolunga . Results of my PhD studies show that:
- The composition of black spot pathogens changes over time and across locations.
- Relative host resistance against black spot is determined by individual pathogens.
- Pathogens in black spot complex cause significant disease on epicotyls and roots.
- The infection process of Phoma koolunga is different on stems versus leaves and resistant versus susceptible pea genotypes.
