- Abstract
Fusarium species were isolated from roots, crowns, basal petioles but rarely from the leaves of infected pyrethrum ( Tanacetum cinerariifolium) plants showing poor growth and stunting in yield-decline sites of northern Tasmania and the Ballarat region of Victoria, Australia. Multigene phylogenetic analyses using the internal transcribed spacer (ITS), the polymerase II second largest subunit ( RPB2) and the partial translation elongation factor 1-α ( EF1) sequences, identified F. oxysporum and F. avenaceum as the most frequently isolated species associated with root and crown diseases of pyrethrum, and F. equiseti and F. venenatum at a low incidence. Pathogenicity trials confirmed that F. oxysporum and F. avenaceum significantly affected growth of pyrethrum plants causing Fusarium crown rot; however, F. avenaceum was less pathogenic than F. oxysporum. Fusarium oxysporum and F. avenaceum may be part of a complex of pathogens that are involved in pyrethrum yield-decline.
