To develop lentil cultivars with improved resistance to ascochyta blight. To continue filling the gaps in knowledge of the epidemiology and control of ascochyta blight of lentil, specifically by: i) determining the longevity of the pathogen in the field on plant residues and in the soil, ii) studying the effects of desiccants on quality and percent ascochyta infection of seed, iii) assessing the possibility of disease control through seed treatment. To investigate the possibility that post-emergent herbicides affect the development of ascochyta blight in crops. To initiate a study of the importance in Manitoba of a new lentil disease caused by Colletotrichum truncatum.
