Other common names:
Verrucalvus flavofaciens is the primary disease of turf and pasture types of kikuyu. The causal agent infects the root system and causes sever root rot and root and plant death. As an oomycete the pathogen thrives in the presence of high soil moisture and the disease favours warm conditions in spring and summer (Bransgrove, 2006).
Typical turfgrass disease symptoms are observed which are expressed as yellowing of the turfgrass. The yellowing becomes circular in shape and expands as the infection continues to worsen. The patches could be 10 cm up to 1 m in size. The centre of the circle dies and the kikuyu does not regrow. The death often results in weeds dominating this area (as pictured).
