Description

Most of the existing pasture disease evaluation methodology has been developed for temperate grass and legume monocultures. Many techniques have been derived from annual crops with little modification and limited research has been done on perennial grass-legume pastures. Perennial pastures are heterogenous communities of various species of many ages supporting continuous pathogen associations. Because of temporal and spatial variation, diseases are difficult to evaluate and techniques are largely inadequate.
