Key Distinguishing Feature
Leaves produce a dark brown, black greasy substance(exudate). Helmo is more common following periods of excess rainfall.
The symptoms of Helmo turf diseases vary, depending upon the specific pathogen, grass species, weather conditions, and cultural conditions involved. In general ‘Black Helmo’ produces small dark spots or patches of dead of dying grass (melting out), which do not measure more than about 10 cm in diameter.
Leaf tissues turn yellow around these lesions and in severe cases the infected plant dies.
