Abstract
Phoma ligulicola Boerema was isolated from diseased buds, and necrotic stem and leaf lesions in 24 pyrethrum fields approaching their first harvest in northern Tasmania. Despite the ubiquitous distribution of this pathogen, marked differences in disease severity were evident in several fields. A higher incidence of disease was noted in fields with a southerly exposure and low areas within fields than on sites with a northerly exposure and hill crests. In 52% of the fields surveyed, P. ligulicola was associated with reduced yields of pyrethrin (kg ha-1 active ingredient) of up to 100%.
