This chapter provides an overview of the wheat rust pathogen lifecycle that has been critical to the design of effective disease management strategies and discusses recent integration of basic biological knowledge and genomic-led tools within an epidemiological framework. Furthermore, we include a case study on the “field pathogenomics” technique, illustrating the value of genomic-based tools in disease surveillance activities.

However, cereal crops are prone to attack by plant pathogens that cause devastating losses estimated in the billions of dollars, threatening global food and economic security. One of the diseases of small grain cereals that is of major economic importance is Fusarium head blight (FHB). It affects all small grain cereals, but major economic losses occur in wheat and barley production. FHB is caused mainly by Fusarium species in the Fusarium graminearum species complex, of which F. graminearum is the predominant causal agent. Understanding the epidemiology of F. graminearum is critical to the development of effective and sustainable FHB management strategies that will reduce or prevent losses.

The causal pathogen, Ramularia collo-cygni is poorly understood but it has been shown to have a complex life cycle and the ability to exist on many hosts in an endophytic state. The rate of development of fungicide resistance in the fungus is also extremely fast and many of the major single site fungicides are no longer effective in many countries. With multisite fungicides having their approval or reconsidered and no consistent varietal resistance available, control of the disease is increasing challenging.

They occur as net form net blotch, caused by Pyrenophora teres f. teres and spot form net blotch caused by P. teres f. maculata. Both sexual and asexual reproduction play a role in the P. teres disease cycles leading to changes in genetic variation of populations. Breeding programs have to keep pace with pathogenic changes and ensure different sources of resistance are present in current barley cultivars. Knowledge of the genetic architecture and genes involved in virulence is thus vital to increase the durability of net blotch resistance in barley cultivars.
