This pathogen affects sugarcane (Saccharum officinarum) and close relatives; a few members of Poaceae as well: citronella (Cymbopogan citratus), elephant grass (Pennisetum purpureum), pearl millet (Pennisetun glaucum) and barnyard grass (Echinochloa).

[1] This fungus takes most of its economic notoriety for the yield losses sustained to sugarcane in commercial agriculture.

[4] Different iterations of these toxins are specific to hosts; while sugarcane is the most economically significant, eye spot has been recorded on ferns in Florida, wheat in Iran, and banana in Brazil.

[5] Depending on severity, foliar applications of fungicide (2% copper oxychloride) may be used but are not practical because resistant varieties are common and garner just as much yield and quality.

It likes moist, humid areas, and thrives with cooler night temperatures—these encourage production of the toxin.
